Company profile
C onstantly
growing all over the world
I ndustrial
A product line designed both for air-conditioning (homes or technological installations)
and for industrial cooling processes. With chillers and heat pumps as its main reference
points, Uniflair aims to offer its customers a series of complementary products,
many of which are highly innovative, combined to produce complete, reliable,
energy-efficient systems with the least possible environmental impact.
Uniflair was founded at the end of 1988 and quickly managed to conquer an
important position among the biggest manufacturers in the world of air conditioning
for technological application, as well as chillers and modular access flooring.
Initially it only dealt with the national market, however Uniflair’s expansion has
now reached Europe and the other continents. It currently has over 60 distributors.
The company’s considerable expansion has made it necessary to adapt its working
space. Thus, from the first factory measuring 1,200 m², Uniflair has recently moved
to a new site which, with a surface area of over 120,000 m², makes use of a
production area of 30,000 m², training rooms, conference halls and one of the most
innovative research centres in Europe.

and residential and cooling systems
air conditioning units
When it comes to air-conditioning rooms and stuctures containing technological
equipment, Uniflair is recognized as one of the world’s market leaders for the quality and
reliability of its units, as well as for its innovative application solutions. Telephone
exchanges, computer centres, laboratories and control rooms require specific
products offering top levels of efficiency and great reliability. Wherever optimal
functioning of hi-tech processes is a priority, our products assure the right room
temperature and humidity conditions by recirculating and filtering the air, cooling,
reheating, dehumidifyng and humydifing. All activities are performed under the
strict control of microprocessor-based controllers for intelligent management of
the system’s operating sequence.
and innovation
Innovation has always been the mainstay of Uniflair’s development:considerable
company resources have been invested in research into new application solutions
intended to assure product excellence with an unbeatable level of reliability. The
whole production and management system is run based on an ISO 9001 certified
quality model.
M odul ar
access flooring
Uniflair has a series of cutting-edge systems capable of producing various kinds of
flooring. Some are exclusive, patented solutions, and in total have an annual capacity
of around one million mq. All process of the processes are supervised by control
systems, which check the manufacturing process every step of the way. Apart
from being a functional element essential to the building’s flexibility, Uniflair access
floors can also be used to add a high-quality architectural and aesthetic dimension
to the interior.

controls
Text
Uniflair produces the software for its units internally. This enables the company to equip each machine with a “tailor
made” control which manages all aspects of the unit.
Absolute control means:
•
•
•
•
Precision: the units use advanced algorithms to accurately control the
temperature of the chilled water
Reliability: each component is continuously monitored to guarantee it is always
used within operating limits and will signal any faults before breakdown occurs
Local Area Network: Aquaflair chillers can “talk” to each other, resulting in
excellent control of multi-unit systems, managing all the cooling resources and
units on stand-by (either on a time basis or alarm)
Connectivity: Uniflair microprocessor controls can “talk” to the most common
supervision systems (Building Management Systems) including: Modbus,
Bacnet, LonWorks, Trend, Metasys, TCP/IP and SNMP
Fig. A
Mechanical cooling operation
15° C
This operating principle uses external air to remove the heat from the liquid to be
cooled, providing the system requirements at no cost. Therefore, the lower the
ambient temperature during operating hours is, the greater the energy savings
are. The sophisticated microprocessor control automatically manages operation in three different situations. During summer, the unit acts like a traditional
air-cooled chiller (Fig. A). As the outside temperature drops, the air can be used
directly to pre-cool the water, thus lowering the number of hours the compressor is
in operation (Fig. B). Should the ambient temperature be such that it is possible
to supply all the cooling capacity the system requires, the compressors will be
excluded and the water chilled using external air only (Fig. C).
This technology makes it possible to drastically reduce energy consumption, cut
compressor operating hours and increase reliability.

Free-cooling
Intelligent Free-cooling
By combining free-cooling and Redundancy logic
(n+1 / n+n), it is possible to also exploit the air/water
exchangers of the unit(s) in stand-by.
By connecting all of the air/water exchangers, it is
possible to make the water which is to be cooled flow
all of the available exchangers, therefore increasing the
Free-cooling capacity.

• The EPAC/F series units have been specially studied and designed
for 4 tube or 2 tube systems where there is the need for a domestic
hot water supply. They provide for producing hot and cold water
contemporaneously in two separate circuits, regardless of the
outdoor temperature. Moreover the units provide for producing
hot or cold water depending on the needs. A 4 tube user system
must be provided. The microprocessor control will automatically
manage the operation mode in order to satisfy the load in the most
energetically efficient manner
• EPAF series units are fitted with a free-cooling device, completely
managed by the microprocessor control. When part of the system
is being used for technological systems with a continuous demand
for chilled water, free-cooling operation leads to a considerable
saving in electric consumption
• Self-suppor ting, galvanised steel frame, and panels with an
(colour RAL7037) epoxy powder finish
• Two hermetic Scroll compressors with internal thermal protection,
crankcase heaters and anti-vibration supports
• One cooling circuit conforming to EC norms (PED 97/23 /CE)
in copper tubes including : filter dr yer, filter shut-of f valve,
flow indicator, thermostatic valves with external equalisation,
Electronic Expansion Valve, high and low pressure switches and
high pressure transducer
• “SOF T” inversion chilling side cycle with the aid of solenoid
valves, without 4 way inversion valve
• Stainless steel brazed plate heat exchanges insulated with closed-cell
expanded polyurethane
• Heat exchanger coil with aluminium fins and internally grooved
copper tubes
• Free-cooling coils with aluminium fins and mechanically expanded
copper tubes
