COST OR RELIABILITY?
THE DILEMMA OF MODERN SYSTEM ENGINEERING APPLICATIONS
Air-conditioning systems in trade centres influence both the starting investment and monthly management costs, for the whole
of their working lives.
This theme is even more relevant in residential applications with centralised systems . Furthermore, maximum working
flexibility requirements should be added to that, in serving different users while avoiding wasting energy and thus, money.
Finally, there are several industrial applications which require chilled water as service fluid, process fluid or vector fluid for
operator comfort and for conserving goods and enabling cycles to function correctly.
Furthermore, in all these cases, the working reliability of the system is decisive.
THE HIGH EFFICIENCY HYDRONIC SYSTEMS ARE EXTREMELY
VERSATILE, RELIABLE AND WIDESPREAD
Despite their apparently low costs, split, multi-split and VRF direct expansion
systems have a lot of limits in these applications. For example, they require a
separate system for primary air treatment. The pipes that contain the refrigerant
cross the served rooms and therefore they are subject to restrictions and use
limitations. They cannot operate in the freecooling mode, the high efficiency and
convenient mode that allows energy savings.
the hydronic systems are certainly more complete and versatile. They make it
possible to adopt various types of terminals in the served environment, from fan
coil units exposed or integrated in the furnishings, up to radiant or induction
systems. They are also irreplaceable in the service and process industrial
applications.
The main component performances , like air-cooled liquid chiller, are checked
and certificated by Eurovent.
CLIVET CHILLERS REDUCE CONSUMPTION
AND ARE COMPACT AND RELIABLE
With over twenty years of technological evolution, Clivet liquid
chillers and heat pumps represent the state of the art in
air-conditioning in residential, trade and industrial environments.
Their success is based on high energy efficiency, compactness
and management and maintenance simplicity, with wide versatility
in the choice of the most suitable model for the specific use.

ELFOEnergy LARGE2 TECHNOLOGY IS THE ENERGY REFERENCE POINT
FOR LIQUID CHILLERS
MAXIMUM EFFICIENCY IS ASSURED BETWEEN THE 25% AND
THE 75% OF THE SYSTEM LOAD
For maximum loads taking place only for a few hours of functioning
per year. The high efficiency at partial loads of ELFOEnergy
LARGE2 makes it much more competitive and efficient than other
solutions.
* EUROVENT (ESEER) supply times reference and ARI (IPLV) reference for
THE MODULAR SCROLL
IS THE EXCELLENT SOLUTION FOR PARTIAL LOAD
seasonal efficiency calculations.
ELFOEnergy LARGE2 uses Scroll-type high-efficiency compressors,
with optimized spirals.
Main advantages are:
Compressors manufactured in large numbers at industrial level,
with strict quality checks and highest reliability thanks to the
elevated production volumes.
With two different-sized compressors, in order to achive more
adjustment steps. So it is possible to supply for usage only the
energy that is actually require.
Efficiency increases by over 50% when operating at partial
loads, thanks to the larger heat exchange surfaces available.
The electronic expansion valve contributes to the excellent
performance (EEV) it adapts rapidly and precisely to the actual load
required for usage, and the high performance heat exchangers.
Example refers to a WSAT-XEE 352, EXCELLENCE. Version.
External temperature equal to 35°C / 30°C / 25°C, respectively.
VERY HIGH HEAT EXCHANGE EFFICIENCY
Thanks to the external ELFOEnergy LARGE2 coils, equipped with wide frontal surfaces and reduced depth, the following is
obtained:
An improvement in the working temperature of the chiller circuit and, therefore, its efficiency, since the approach
between the air temperature and the temperature of the chiller fluid inside the exchanger is reduced;
A reduction in consumption by the fans, thanks to the reduced depth of the exchanger which decreases air flow renewal
drops. Furthermore, the automatic fan speed control, supplied in series, minimises the air renewal air requirement to
function correctly and therefore further reduces consumption;
A decrease in the sound level, since greater surfaces enable slower air speed in the exchangers.
ECOBREEZE ELECTRONICALLY-CONTROLLED FAN TECHNOLOGY
The external axial fans are equipped with an innovative Winglet blade profile with an integrated deflector, which is able to
increase aerodynamic efficiency. This results in a 10% reduction in consumption. The average acoustic emission is 6 dB
less then traditional fans.
Using ECOBREEZE the external rotary electric motor is operated by a continuous magnetic
switching of the stator, induced by integrated electronic control. The advantages are:
70% increase in efficiency thanks to the brushless technology and the special electricity
supply;
Increase in the working life, thanks to the elimination of the brush wear;
Reduction in the electrical consumption by the system, thanks to a drastic reduction of the
inrush current for the fans obtained using the integrated ‗Soft start‘ function.
Note: ECOBREEZE is supplied as standard in the EXCELLENCE version
COMPLETELY AUTOMATIC FUNCTIONING
The microprocessor controller manages functioning automatically in line with maximum
efficiency criteria, enables up to 6 units to be coordinated in a local network (Master-Slave
function) and includes numerous safety functions and the management of any alarms.
The interface terminal is equipped with a backlit graphic display and a multifunction access
keyboard. The multi-level menu is protected by passwords which are differentiated by different
user types. The daily / weekly clock programmer function is standard.
Thanks to its attractive design, the interface terminal can also be positioned inside the rooms
being serviced or in a special system control room.

ELFOEnergy LARGE2 TECHNOLOGY ENABLES
THE SYSTEM TO BE INDUSTRIALISED
ELFOEnergy LARGE2 can be supplied complete with system components which are often provided as external to units.
Thus reducing:
Design time: all the accessories are created to guarantee the best overall performance;
Installation costs: the accessories which are already connected manually, electrically wired and individually checked are
ready to start working immediately;
Dimension: integration of system members into the unit reduces technical spaces and increases the space available for
other uses. The slim line structure enables it to be positioned even on terraces or in external service corridors.
THE ON-BOARD PUMPS ARE VERSATILE, READY-FOR-USE AND RELIABLE
The various solutions available are:
Standard pump, with a wide range of available heads.
Standard pump with emergency pump. The on-board microprocessor balances its
working hours and in case of any breakdown signals the fault and automatically activates
the reserve pump.
HYDROPACK, the modular solution with two parallel pumps. Automatically reduces
water flow in critical conditions, avoiding blocks due to overloading and consequential
interventions by specialised technical personnel. It is very useful during start-up, during
re-start after a pause in working (e.g. a weekend) or after a long period of inactivity. In
case of any pump breakdowns, the unit continues to function with 60% of the nominal
flow.
EVEN THE STORAGE TANK AND THE PRIMARY CIRCUIT CAN BE INTEGRATED ON-BOARD
A connection to the secondary use circuit is all that's needed. In this way, the system results even more simple and
reliable. The units are complete with rapid connections on the hydraulic side, which further reduces set-up times by
eliminating pipe threading operations.
Furthermore, other system components are also available as accessories, such as hydraulic attachments reported on the
external walls of the unit (as standard with pumps and/or storage tank) and the required water filter.

Free hot water production for :
Supplying hot-water coils for post-heating;
Producing domestic hot water (with the intermediate exchanger);
Other processes or operations.
IT EXPLOITS EXTERNAL AIR FOR COOLING WITHOUT ACTIVATING THE COMPRESSORS
In the FREE-COOLING configuration, as soon as the external conditions enable it, the unit is able to cool the liquid reducing
compressor functioning up to their complete withdrawal. This configuration is particularly useful in applications with a
high number of room loads, since it notably reduces unit energy consumption and compressor wear.

Data referred to the following conditions :
- internal exchanger water = 12/7°C
- external exchanger air 35°C
- still air
The functioning mode can also be extended up to external air temperatures of less than 39°C, but only with a FREE-COOLING configuration which is complete with an adequately
sized "Electric panel anti-frost protection" option.
Warning: the still air condition is meant as absence of air flow to the unit. Any wind
condition can let air pass through the condenser coil thus worsening the operating limits of
the unit. In case of predominant winds, windbreak barriers are necessary.
In the Standard unit (not the FREE-COOLING configuration) with an empty hydraulic circuit,
which has no electricity supply, correct maintenance (not functioning) is possible up to an
external air temperature of -20°C.
Note. For correct maintenance (not functioning) with external air temperatures at less than
-10°C, the Standard unit (not the FREE-COOLING configuration) must be equipped with the
"Electric panel anti-freeze protection" option and be continuously supplied with electricity.
The hydraulic circuit must be filled with an adequate percentage of anti-freeze. In this
condition, the minimum external air-temperature which is permitted depends on the chosen
model of "Electric panel anti-freeze protection" option, up to a limit value of -39°C.
(1) Max inlet temperature - unit at full load
(2) Max inlet air temperature - Unit at partial load
(3) Min inlet air temperature - Unit at full load and still fresh air
(4) Min inlet air temperature - Unit at partial load and still fresh air
(5) Min inlet air temperature - unit at partial load and air speed of 0.5 m/s.
(6) Min inlet air temperature - unit at partial load and air speed of 1 m/s.

To the internal exchanger pressure drops must be added the pressure drops of the steel mesh mechanical filter that must be placed on the
water input line. It is a device compulsory for the correct unit operation, and it is available as Clivet option (see the HYDRONIC GROUP
ACCESSORIES).
If the mechanical filter is selected and installed by the Customer, it is forbidden the use of filters with the mesh pitch higher than 1,6 mm,
because they can cause a bad unit operation and also its serious damaging.

The functioning mode can also be extended up to external air temperatures of less than 39°C, but only with a FREE-COOLING configuration which is complete with an adequately
sized "Electric panel anti-frost protection" option.
Data referred to the following conditions :
- internal exchanger water = 12/7°C
- external exchanger air 35°C
- still air
In the Standard unit (not the FREE-COOLING configuration) with an empty hydraulic circuit,
which has no electricity supply, correct maintenance (not functioning) is possible up to an
external air temperature of -20°C.
Warning: the still air condition is meant as absence of air flow to the unit. Any wind
condition can let air pass through the condenser coil thus worsening the operating limits of
the unit. In case of predominant winds, windbreak barriers are necessary.
(1) Max inlet temperature - unit at full load
(2) Max inlet air temperature - Unit at partial load
(3) Min inlet air temperature - Unit at full load and still fresh air
(4) Min inlet air temperature - Unit at partial load and still fresh air
(5) Min inlet air temperature - unit at partial load and air speed of 0.5 m/s.
(6) Min inlet air temperature - unit at partial load and air speed of 1 m/s.
(7) Standard unit without low temperature liquid device and external exchanger air intake
35°C
(8) Unit with low temperature liquid device and external exchanger air intake 35°C
Fluid with ethylene glycol of 40%
Note. For correct maintenance (not functioning) with external air temperatures at less than
-10°C, the Standard unit (not the FREE-COOLING configuration) must be equipped with the
"Electric panel anti-freeze protection" option and be continuously supplied with electricity.
The hydraulic circuit must be filled with an adequate percentage of anti-freeze. In this
condition, the minimum external air-temperature which is permitted depends on the chosen
model of "Electric panel anti-freeze protection" option, up to a limit value of -39°C.

The sound levels refer to the unit at full load, in the rated test conditions.
The sound pressure level refers to a distance of 1m from the external
surface of the units operating in an open field.
Measures, according to ISO 3744 regulations, are carried out on a
reflecting surface, with respect to the EUROVENT 8/1 certification.
Data referred to the following conditions:
- internal exchanger water = 12/7°C
- outdoor air temperature 35°C
The sound levels indicated sideways are valid only for the operating
range of the ‗Extremely low noise EN‘ configuration; with fresh air
temperatures higher and in any case into the operating range of the
‗Compressor soundproofing SC‘ configuration, consider the sound levels
of the ‗Compressor soundproofing‘ configuration .

To the internal exchanger pressure drops must be added the pressure drops of the steel mesh mechanical filter that must be placed on the
water input line. It is a device compulsory for the correct unit operation, and it is available as Clivet option (see the HYDRONIC GROUP
ACCESSORIES).
If the mechanical filter is selected and installed by the Customer, it is forbidden the use of filters with the mesh pitch higher than 1,6 mm,
because they can cause a bad unit operation and also its serious damaging.

The functioning mode can also be extended up to external air temperatures of less than
-39°C, but only with a FREE-COOLING configuration which is complete with an adequately
sized "Electric panel anti-frost protection" option.
Data referred to the following conditions :
- internal exchanger water = 12/7°C
- external exchanger air 35°C
- still air
In the Standard unit (not the FREE-COOLING configuration) with an empty hydraulic circuit,
which has no electricity supply, correct maintenance (not functioning) is possible up to an
external air temperature of -20°C.
Warning: the still air condition is meant as absence of air flow to the unit. Any wind
condition can let air pass through the condenser coil thus worsening the operating limits of
the unit. In case of predominant winds, windbreak barriers are necessary.
(1) Max inlet temperature - unit at full load
(2) Max inlet air temperature - Unit at partial load
(3) Min inlet air temperature - Unit at full load and still fresh air
(4) Min inlet air temperature - Unit at partial load and still fresh air
(5) Min inlet air temperature - unit at partial load and air speed of 0.5 m/s.
(6) Min inlet air temperature - unit at partial load and air speed of 1 m/s.
(7) Standard unit without low temperature liquid device and external exchanger air intake
35°C
(8) Unit with low temperature liquid device and external exchanger air intake 35°C
Fluid with ethylene glycol of 40%
Note. For correct maintenance (not functioning) with external air temperatures at less than
-10°C, the Standard unit (not the FREE-COOLING configuration) must be equipped with the
"Electric panel anti-freeze protection" option and be continuously supplied with electricity.
The hydraulic circuit must be filled with an adequate percentage of anti-freeze. In this
condition, the minimum external air-temperature which is permitted depends on the chosen
model of "Electric panel anti-freeze protection" option, up to a limit value of -39°C.

To the internal exchanger pressure drops must be added the pressure drops of the steel mesh mechanical filter that must be placed on the
water input line. It is a device compulsory for the correct unit operation, and it is available as Clivet option (see the HYDRONIC GROUP
ACCESSORIES).
If the mechanical filter is selected and installed by the Customer, it is forbidden the use of filters with the mesh pitch higher than 1,6 mm,
because they can cause a bad unit operation and also its serious damaging.

The functioning mode can also be extended up to external air temperatures of less than 39°C, but only with a FREE-COOLING configuration which is complete with an adequately
sized "Electric panel anti-frost protection" option.
Data referred to the following conditions :
- internal exchanger water = 12/7°C
- external exchanger air 35°C
- still air
In the Standard unit (not the FREE-COOLING configuration) with an empty hydraulic circuit,
which has no electricity supply, correct maintenance (not functioning) is possible up to an
external air temperature of -20°C.
Warning: the still air condition is meant as absence of air flow to the unit. Any wind
condition can let air pass through the condenser coil thus worsening the operating limits of
the unit. In case of predominant winds, windbreak barriers are necessary.
(1) Max inlet temperature - unit at full load
(2) Max inlet air temperature - Unit at partial load
(3) Min inlet air temperature - Unit at full load and still fresh air
(4) Min inlet air temperature - Unit at partial load and still fresh air
(5) Min inlet air temperature - unit at partial load and air speed of 0.5 m/s.
(6) Min inlet air temperature - unit at partial load and air speed of 1 m/s.
(7) Standard unit without low temperature liquid device and external exchanger air intake
35°C
(8) Unit with low temperature liquid device and external exchanger air intake 35°C
Fluid with ethylene glycol of 40%
Note. For correct maintenance (not functioning) with external air temperatures at less than
-10°C, the Standard unit (not the FREE-COOLING configuration) must be equipped with the
"Electric panel anti-freeze protection" option and be continuously supplied with electricity.
The hydraulic circuit must be filled with an adequate percentage of anti-freeze. In this
condition, the minimum external air-temperature which is permitted depends on the chosen
model of "Electric panel anti-freeze protection" option, up to a limit value of -39°C.

The sound levels refer to the unit at full load, in the rated test
conditions.
The sound pressure level refers to a distance of 1m from the external
surface of the units operating in an open field.
Measures, according to ISO 3744 regulations, are carried out on a
reflecting surface, with respect to the EUROVENT 8/1 certification.
Data referred to the following conditions:
- internal exchanger water = 12/7°C
- outdoor air temperature 35°C
The sound levels indicated sideways are valid only for the operating
range of the ‗Extremely low noise EN‘ configuration; with fresh air
temperatures higher and in any case into the operating range of the
‗Compressor soundproofing SC‘ configuration, consider the sound
levels of the ‗Compressor soundproofing‘ configuration .

To the internal exchanger pressure drops must be added the pressure drops of the steel mesh mechanical filter that must be placed on the
water input line. It is a device compulsory for the correct unit operation, and it is available as Clivet option (see the HYDRONIC GROUP
ACCESSORIES).
If the mechanical filter is selected and installed by the Customer, it is forbidden the use of filters with the mesh pitch higher than 1,6 mm,
because they can cause a bad unit operation and also its serious damaging.

CONFIGURATIONS
Consult the appropriate table, shown in the final section, to verify the compatibility between the different options.
B - WATER LOW TEMPERATURE
Configuration also known as "Brine". Enables a non-freezable solution to be cooled (for instance, water and ethylene glycol in
appropriate quantities) up to a temperature of between +4°C and –7°C.
Includes:
- Appropriate exchangers, complete with thick closed-cell insulation;
- Electronic-type expansion valve, functional calibration and safety devices adapted to the particulars of use.
In the selection phase, it is necessary to indicate the type of function required, and the unit will be optimised with:
- Unit with single working set-point (only at low temperature)
- Unit with double working set-point.
The unit in this configuration have a different operation field, indicated on the previous pages.
In the low temperature operation, some partialisation degrees could be not available. For more information, contact our Sales Department.
D - PARTIAL ENERGY RECOVERY
Configuration
which
allows
hot
water
production
free-of-charge during the cooling function, thanks to the
recovery of part of the condensation heat which would
otherwise be disposed of into the external heat source.
This configuration is also known as "desuperheating coil". It is
made up of brazed-plate exchanger in AISI 316 stainless steel
which is ideal for recovering around a quarter of the heating
capacity of the unit (equal to the sum of the cooling capacity
and the absorbed power input of the compressors).

The partial recovery device is considered to be working when
it is supplied by the flow of water to be heated. This condition
improves the unit performance, since it reduces the
condensation temperature: in nominal conditions, the cooling
capacity increases indicatively by 3,2% and the absorbed
power input from the compressors is reduced by 3,6%.

TW out
7°C
When the temperature of the water to be heated is particularly
low, it is opportune to insert a flow regulation valve in the
hydraulic circuit, to maintain the recovery output temperature
at higher than 35°C and thus avoid refrigerant condensation in
the partial energy recovery device.

R - TOTAL ENERGY RECOVERY
Configuration which allows hot water production free-of-charge during the cooling function, thanks to the total recovery of the
condensation heat which would otherwise be discharge into the external heat source. This solution increases the overall
efficiency of the system in all cases in which a high-level of hot water production is requested.
It is made up of 316 Stainless steel brazed plate heat exchanger, which is ideal for recovering the entire unit heating capacity
(equal to the sum of the cooling capacity and the absorbed power input of the compressors), from the on-of type solenoid
valves, the temperature sensors for the hot water circuit supply and return and the relative integrated logic controller with two
partialisation steps.
La disponibilità di acqua calda è sempre subordinata alla produzione di acqua refrigerata. Si veda il seguente esempio:
1. Cooling capacity request = 100% / Heat capacity request = 0%→ Cooling capacity production only.
2. Cooling capacity request = 100% / Heat capacity request = 100%→ Cooling capacity production and heat capacity
production by recovery.
3. Cooling capacity request = 50% / Heat capacity request = 100%→ Cooling capacity production and heat capacity
production by recovery, equals 50% of the requested heat capacity.
To avoid constant switching in the cooling circuit should be added to a adequate capacity storage tank in the hot water circuit of the
system.
If the hot water circulation is not present on the heat recovery exchanger, the maximum inlet air temperature decreases of about 2 °C
compared to units without 'Total Energy Recovery'.
TOTAL ENERGY RECOVERY OPERATING
TOTAL ENERGY RECOVERY NOT OPERATING
When hot water is required, the condensing coil is turned off.
The condensation takes place entirely in the recovery circuit.
When the set-point recovery is fulfilled, the coil is reactivated. In this
condition the total recovery circuit operates as a partial recovery
(desuperheater).

FCD - DIRECT FREE-COOLING
Configuration which enables great savings on the management costs of the system in applications which require chilled
water even during cold seasons like, for instance, industrial processes, data centres, telecommunications, technological
applications and trade centres.
When the external air temperature is less than the temperature of the return water in the system, the FREE-COOLING system
recovers coolness from outdoor and reduces the compressor working up to their being withdrawn completely.
The higher the temperature of the chilled water in the system (e.g. 10-15°C instead of 7-12°C), the greater the field of application of
the FREE-COOLING system and, therefore, the energy saving.
USING UNFREEZABLE SOLUTIONS
The FREE-COOLING configuration is particularly indicated in buildings where, at least at certain times of the year, the external air
temperature also reaches very low values. For this reason, the liquid must be protected from the risk of freezing, typically by adding
an appropriate anti-freeze substance such as ethylene glycol. The percentage of glycol in the solution depends on the minimum
temperature value foreseen in the installation area, and in any case, remains within the main parameters of the system design.
TECHNICAL DESCRIPTION
In comparison with standard units, Clivet units in the direct FREE-COOLING configuration also include:
three-way switching valve with on/off regulation
Finned water-air COIL exchanger (FREE-COOLING coil)
additional outdoor air temperature sensor and control logic dedicated
flush hydraulic connections.
5
MANAGEMENT LOGIC
There are three main function modes, which can be differentiated in essence
by the position of the three-way switching valve and by the number of active
compressors.
(A) SUMMER SEASON
In the summer, with external air temperatures greater than the return
temperature of the system liquid, the three-way valve is switched in such a way
as to exclude the FREE-COOLING coils.
The cooling of the liquid is referred to the direct expansion circuit, via the
workings of the compressors as in a traditional chiller.
(B) INTERMEDIATE SEASON
During the intermediate season, or rather when the external air temperature is a
little less than the temperature of the return water in the system, when the
system senses that the external air temperature conditions are favourable:
it switches the position of the three-way valve forcing the solution to transit
through the FREE-COOLING coils before reaching the evaporator;
it puts the fans to their maximum speed to exploit as much as possible the
solution cooling using the outdoor air ;
it undertakes the initial cooling of the solution in a "natural and free" way;
it supplies any missing capacity through the chiller cycle, using the
compressors functioning partially (the absorbed power input is proportional to
the level of partialisation).
In case of an increase in the external air temperature, the microprocessor
automatically converts the unit functioning to the summer setting, guaranteeing
the conditions requested by the user at all times.

(C) WINTER SEASON
During the winter season, with the temperature of the external air lower than the
temperature of the return water in the system, the system senses that conditions
are favourable for the FREE-COOLING function:
the three-way valve is switched as in the previous case, forcing the solution
to transit through the FREE-COOLING coils before reaching the evaporator;
the external air temperature brings the solution to the FREE-COOLING coil
output already at the temperature requested by the user;
the microprocessor management totally deactivates all the compressors
supplying all the requested cooling capacity AT NO COST, in contrast to
traditional chillers.
The difference between the outdoor air temperature and that requested by the
user can also be such as to lower the solution temperature at the
FREE-COOLING coil output to below the set-point requested for this use. This is
a condition which does not compromise unit safety thanks to the presence of
anti-freeze in the solution. The microprocessor modulates the fan speed until
their withdrawal.
If, with all the fans switched off, the temperature continues to go down, the
three-way valve automatically positions itself in the summer setting, thus
enabling the set-point to be maintained.

When the outside air temperature increases, the cooling capacity of FREE-COOLING decreases (at the same temperature of
water on returning from). If you know the cooling capacity required by the system, you can calculate the maximum outside air
temperature from which the cooling capacity is available through FREE-COOLING. Below this temperature, the required power
is supplied only by modulation of the air flow fans.

FANQE - ELECTRICAL PANEL VENTILATION
This option is necessary for very hot climates, where the external temperature can be between +40°C and
+50°C. It is made up of a forced ventilation system, activated by a thermostat, which provides for the
correct usage temperature to be maintained by the components inside the electrical panel. The option
includes a thermostat which activates forced ventilation when necessary.
The device is installed and tested built-in.
This accessory functions at all times even when the unit is switched off as long as the electricity supply is
maintained and the unit is not isolated.
In order to guarantee that the correct unit operation, the temperature inside the unit must not exceed 50°C.
Therefore, during storage or when the unit is already installed but not powered, it is necessary to avoid exceeding
the above-indicated temperature. When the unit has been installed, the protection and safety devices are only
active with the power supply switched on and the unit not isolated.
RE-20 / RE-25 / RE-30 / RE-35 / RE-39 - PROTEZIONE ANTIGELO QUADRO ELETTRICO
This option is necessary for very cold climates, where the external temperature can be between -10°C
and -39°C. It includes thermostat self-regulating heaters which are able to protect the electric panel from
condensation and frost, guaranteeing its correct operation. The selection of devices is carried out based
on the minimum temperatures reached at the unit installation site.
The device is installed and tested built-in.
This accessory is necessary for the correct unit operation in the FCD (FREE-COOLING) configuration with
external temperatures below –10°C. Furthermore, it is necessary for the units to be maintained correctly in all the
remaining configurations (not functioning).
This addiction element stay always switch on also when the unit is switch off as long as to keep the supply power
on.
This accessory does not lead to substantial variations in the electrical data of the unit declared in the section Electrical Data.
PM - PHASE MONITOR
The phase monitor makes it possible to check the correct connection of the phases and their imbalance in
units powered with a tri-phase system. If the connection of the phases is not correct, or the threshold of
phase imbalance is exceeded, or the voltage is too high or too low for a certain amount of time, the
monitor acts on the control circuit and orders the unit to be shut down. As soon as nominal line conditions
are restored, the unit is automatically reset. As soon as nominal line conditions are restored, the unit reset
is manual.
The device is installed and tested built-in.
PFCP - POWER FACTOR CORRECTION CAPACITORS
The component is necessary to lower the phase difference between current and voltage in the
electromagnetic components of the machine, such as asynchronous motors. By re-phasing it is possible
to reduce the intensity of the line current by reducing a part of the power of the mains (reactive power).
This often leads to an economic benefit which the energy provider grants to the final user. The component
makes it possible to bring the cosfi power factor to values which on average are greater than 0.9.
The device is installed and tested built-in.
SFSTR - BREAKAWAY CURRENT REDUCING DEVICE
I
Option also known as 'Soft starter'. Electronic device that automatically and gradually
starts the compressors reducing the start-up current of about 40% in comparison with
the nominal value. It follows that the electrical power and its protective devices can be
sized with lower parameters , so with a lower cost of initial investment.
