General Features
Condensers
The complete ACUF condensing unit provides an extremely
rugged, heavy duty, long-life and energy efficient that will provide higher efficiency over a long and extended life. What
makes ACUF series the pride of SKM products is the use of:
Condenser coils are manufactured of seamless copper tubes
mechanically bonded to aluminum fins to ensure optimum heat
transfer.
•
Semi Hermetic Reciprocating, heavy duty, energy efficient
compressors.
•
Totally enclosed, Class F insulated, IP55 protected condenser
fan motor.
•
Heavy duty condenser optimised in design for long-life
maintenance free operation.
•
Cabinet construction specifically designed for Gulf climates.
•
IP 54 Electrical panel.
•
Factory installed, advanced and user friendly microprocessor
based control system.
•
Interface capability with major BMS protocols (option).
The SKM ACUF series air cooled condensing units are durable,
dependable, strong, reliable, versatile, quiet and energy efficient.
Wherever a heavy duty condensing unit is required, the ACUF
series should be an automatic choice.
Condenser Coil
All coils are tested against leakage by air pressure of 450 psig
(3100 kPa) under water. All standard coils are 3 or 4 rows/
14 FPI, 3/8” (9.5 mm) O.D. tubes. An integral subcooling circuit
is provided to increase the cooling capacity, without additional
operating cost.
For different application requirements, other optional condenser
fin materials are available:
•
Copper fins.
Component Features
•
Electrotinned Copper fins.
•
Copper finned coils with electro-tinned after manufacturing.
Compressor
•
Precoated Aluminum fins.
The pre-coated is hydrophobic polyurethane resin. This
option provides substantial corrosion protection beyond
standard coil construction.
•
Aeris Guard Coil coating.
The Aeris Guard Coil is a self etching high performance
modified epoxy finish that is specifically designed to coat
and protect Aluminum and Copper surfaces. In addition,
the coating is ideal for the protection of ferrous and non
ferrous materials.
Compressors used in ACUF series are fully accessible,
semi-hermetic, reciprocating type. They are equipped with an
oil sight glass, suction and discharge service valves and
crankcase heater. All compressors are refrigerant gas cooled
and equipped with an oil pressure lubrication system. The oil
pump working in either direction is protected by an oil screen
and a valve provided for the fitting of an oil pressure gauge. For protection, all compressors are equipped with preset internal
relief valve between suction and discharge sides.
The compressors are provided with vibration isolator springs
underneath and therefore, external to ACUF series, AVM’s may
be necessary only for critical applications.
The compressor motors have inherent thermal protection. This
is in addition to other standard safety and protection controls.
Compressors conform to EN 12900 standards.
SKM ACUF series, all models, are restricted to a 14 FPI (1.8
mm) fin spacing condenser coil. Gulf dust storms and the general
level of available maintenance in Gulf countries ensures this
condenser coil design shall provide long life and maintenance-free
operation with the least possibility of operational blockage on
the condenser. Ample condenser surface and sensible air flow across the condenser ensures a low temperature differential
between condensing temperature and the high Gulf ambients
making the ACUF condensing unit perform efficiently and durably.

SKM Air Cooled Condensing Units
ACUF Series - R-22
Electrical Hook-Up
Every SKM ACUF Condensing Unit requires, at most, field intalled fused disconnect switches or circuit breakers, fan interlocks
and 24 volt temperature control thermostat. Refer to typical wiring diagram (page 18) for schematic representation of required field
electrical hook-ups for a standard ACUF Condensing Unit hooked up with an air handling unit.
When option CRS is required, consult SKM for certified Wiring Diagram and Electrical Hook-up (see Page 16 for Capacity Control
Steps - option CRS). All field wiring must be done in accordance with applicable local and national codes. For maximum recommended
fuse sizes and minimum circuit amperes for cable sizing, see Tables 12 - 16 (pages 19-23) of this bulletin.
Field Wiring Schematic
**
** ACUF SERIES UNITS RATED FOR 440V/3Ph/50Hz AND 460V/3Ph/60Hz (3 WIRE SYSTEM)
REQUIRE SEPARATE SOURCE OF CONTROL POWER SUPPLY THRU FIELD SUPPLIED & INSTALLED
15A/220V FUSED CONTROL DISCONNECT SWITCH OR ORDER WITH FACTORY BUILT OPTION 'CXT'.

SKM Air Cooled Condensing Units
ACUF Series - R-22
Location and Space Requirements
SKM ACUF Condensing Units should be located on a flat base, either on the ground or on a roof top, which is strong enough to
hold the operating weight of the unit.
The most important consideration when deciding upon the location of Air Cooled equipment is the provision for supply of ambient
air to the condenser and removal of heated air from the condenser.
For recommended clearances refer to Table 22 below. Where this essential requirement is not adhered to, it will result in a higher
condensing temperature which causes poor operation, and eventual failure of the equipment. Units should not be located in the
vicinity of steam, hot air or fume exhausts.
ACUF Condensing Units should be sited away from noise sensitive places. Units may be mounted on anti vibration mounts suitable
for operating weight, to prevent vibration and noise from being transmitted into the building structure.
Orientation of the ACUF Condensing Units, if possible, to be so that prevailing winds blow against the control panel or access end
of the unit rather than against the condenser coil(s).
For parallel location of multiple ACUF a minimum 50% more than the recommended clearances as shown below should be maintained.
There should be no obstruction above the fans and no ductwork should be connected to any fan outlet.
The ACUF Air Cooled Condensing Units are meant for outdoor installation and may not be protected any further from the elements.
However, on ground level installations option CGP may be desirable for protection of the condenser coil against vandalism.

Refrigerant Piping
Correct design and size of refrigerant piping is necessary for
proper operation. The refrigerant piping generally should be
designed to accomplish the following:
a. To ensure proper refrigerant feed to the evaporator.
b. To provide practical refrigerant line sizes without excessive
pressure drop.
c.
To maintain uniform return of lubricating oil to the compressor.
d. To prevent liquid refrigerant from entering the compressor
and causing compressor damage due to "slugging".
Field Expansion Valve Selection
The following recommendations should be taken into consideration
when selecting expansion valves in field.
1. Expansion valves should be installed as close to the
evaporator as possible, mounted directly to the distributor.
2. The following possible sources of pressure drop to be
considered:
a. Friction losses through refrigerant lines.
b. Pressure drop across valves and controls.
32
c. Pressure drop due to vertical lift of liquid line for R-22; 1°F
(0.55°C) sub cooling must be allowed for each 5.5 ft (1.7m)
vertical rise in order to avoid flash gas forming due to the
weight of the column of liquid refrigerant.
SKM ACUF Series units are designed with a sub cooling circuit
enough to sub cool the liquid 12°F (6.6 °C), which gives the liquid
maximum 66 ft. (20m) lift without additional sub cooling. Liquid
suction heat exchanger can be used for additional sub cooling
in order to avoid flash gas forming.
Matching DX Coil Selection
For single circuit ACUF Series, the DX coil selection in a MAH
or other air handler from SKM should be based on total
capacity. For multiple circuit ACUF Series, extra care should be
exercised and correspondingly split, by face area or number of
rows to correspond and match the capacity split available in the
multiple circuited ACUF Series selected. For optimum matching
the DX coil should be ordered from SKM as well.
SKM provides correct no. of feeds and circuits and properly
sized distribution to ensure the correct split on the DX coil is made
available to match the particular selected ACUF Series model.

Table 23
SKM ACUF Condensing Units are designed for satisfactory operation with single suction line. In some cases of low load operation,
it is recommended connecting a double suction riser for applications having option CRS.
1. Suction Line sizing selection recommendation in Table 23 is based on (2°F) temperature drop.
2. Double suction risers, for applications with systems having large variations in capacity are recommended to ensure proper oil
flow up and return to compressor.
3. Liquid line sizing selection recommendation in table 23 is based on (2°F) temperature drop.
4. Recommended line sizes in Table 23 are for guidance only. For detailed proper piping, consult recognized piping references
like ASHRAE Guide and Data Book for assistance.
SKM is not responsible for faulty or improper design or sizing of refrigerant lines. The above recommendations do not
incorporate necessary slopes, etc. that may be required on horizontal risers, etc.
