CT – CL Range Of Aircooled Condensing Units 

Key to Type Codes 

C-Range of Aircooled Condensing Units 

The C-Range of Aircooled Condensing Units is compact with the higher performance 

and quality demanded by today's close control air conditioning market. 

These units are designed and built using our unrivalled experience in close control 

air conditioning, with extensive testing of components and complete systems. Every 

aspect is engineered to ensure maximum reliability, economy of operation and long 

working life, together with ease of installation and maintenance. 

The Range 

The CT - CL range of Aircooled Condensing Units is now available in twenty three 

(23) models, eighteen (18) Standard (single compressor) versions and five (5) V.R.F. 

(twin compressor) versions as detailed below. Nominal duties range from 5 kW 

through to 75. 

- Standard Versions: CT18, CT22 and CT28 

CS28, CS34 and CS40 

CM40, CM48 and CM61 

CP61, CP72, CP81 and CP90

Specification 


C-Range 

Components are mounted on a rigid galvanised steel base and enclosed by plastic 

coated metal side sections and top lid. The base has plastic coated steel channel 

feet to assist in transporting and sitting the unit. The feet have holes for securing the 

unit in position when installed. The coil and fan(s) are mounted vertically so that air is 

drawn through the coil and discharged horizontally through a plastic-coated wire fan 

guard. The fan(s) and guard(s) are mounted on a galvanised steel diaphragm. The 

compressor and electrical components are mounted in a sealed compartment at the 

end of the unit. 

Access to this compartment is by a removable panel fitted with a door interlocked 

mains isolator. If required, additional access to this area and to the fan(s) can be 

provided by removing the lid and side panels, which are held in place by self-tapping 

screws. 

The refrigerant pipe work between the compressor and condenser is fitted with a 

vibration eliminating connector. The compressor suction pipe work is looped to 

prevent vibration damage. Condenser liquid and compressor suction pipes terminate 

as stub connections protruding through a recessed, galvanised service panel. The 

compressor is protected by HP/LP switches, and condenser pressure is controlled by 

a fan switch. HP/LP service tapings are on the compressor valves. The Condensing 

Units are normally delivered with a 5 psig holding charge of nitrogen. 

An electronic fan speed controller is fitted as standard and selects the optimum 

condenser fan speed based upon the refrigerant condensing pressure as sensed by 

a local transducer. Using this option ensures reliable expansion valve operation 

under external winter ambient conditions as low as -30 °C. 

The winter start kit is fitted as standard to allow positive refrigeration system start up 

under low ambient conditions, this includes a timer to override the low pressure 

switch for up to 5 minutes, until sufficient low side operating pressure is reached. 

When used in conjunction with the GEA Denco C3-05 AH11 controller this function is 

provided within the micro processor controls. 

The compressor(s) are compliant scroll type running on R407C or R134a, are 

complete with isolation valves, crankcase heater, and oil level sight glass. The 

compressor is provided with an electrical contactor. For details of compressor sizes 

fitted to each Condensing Unit, refer to the tables. 

Condenser coils are constructed from three rows deep 3 / 8 " o/d copper inner grooved 

tubes with aluminium fins spaced at 14 per inch. 

The Condensing Units are normally wired for direct starting from the Air Handling 

Unit's controls. A four (4) core 3 phase and neutral cable is required for the power 

supply, which is normally supplied from the MCB’s within the Air Handling Unit. For 

Standard (single compressor) units, a four (4) core cable is required between the Air 

Handling Unit and Condensing Unit for control signal and alarms, whilst for V.R.F. 

(twin compressor) units a seven (7) core cable is required. The HP/LP switches have 

normally open contacts for use when alarm signals are required. These alarms are 

connected into the microprocessor controls using the additional cores in the signal 

cable. 

Signal cables must be segregated from cables carrying mains potential. For long 

cable runs provision must be made for voltage drop.

Unit Location on Site / Condensing Unit Access 

Condensing Unit Access 


C-Range 

Ensure that the site is level and that it can support the weight of the equipment. 

Condensing Units must be located in an unobstructed position to ensure adequate air circulation through the cooling 

coils. Care must be taken to avoid "short circuit" air paths and re-circulation of air from one unit to another. Whenever 

possible position Condensing Units such that they are reasonably sheltered from strong winds and avoid prevailing 

winds blowing directly onto the fan(s). Units should be bolted down in case of high winds. 

Condensing Units should not be sited more than 15 m (50ft) above or 4 m (13ft) below the base of the air 

conditioning unit. 

Please note that ALL GEA Denco Condensing Units are supplied with a 5 psig holding charge of Nitrogen. 

Access space should be provided as detailed on the drawings below but allowing at least one metre free access. 

Condensing Unit Access 

Access is gained by means of a removable panel secured by two screws. The panel also contains the interlocked 

door isolator, which will have to be turned to the “OFF” position, before the panel can be removed. This panel is 

situated on the left-hand side of the unit (looking at the fan). For major service work, such as replacing the 

compressor, the top and side panels may be removed.

Ancillaries and Options 


C-Range 

Fan Pressure Switch 

This can be fitted in place of the fan speed controller switch which is used as 

standard. 

Extra Low Ambient Temperature (ELATE) Kit 

Generally recommended for operation down to –40°C, a liquid receiver is provided 

which, together with two spring operated valves, allows liquid refrigerant to flood 

back into the condenser coil at ambient temperatures below the design maximum. 

The resultant reduction in coil area available for condensing of refrigerant gas allows 

the head pressure to remain within required parameters, although the condenser fan 

runs at full speed. 

Hot Gas Bypass 

A minimum evaporating pressure is maintained by an adjustable, spring operated 

valve that allows hot gas from the discharge line to enter the suction line via a bypass-piping 

loop. To provide compressor motor cooling under high bypass (low 

refrigeration load) conditions, the liquid line is also connected, via a desuperheating 

thermostatic expansion valve, into the bypass line. This arrangement can effectively 

reduce the capacity of the condensing unit to 20% of maximum, and is manually set 

up on site at time of commissioning. 

Turning Vanes 

If vertical air discharge is required, turning vanes are fitted on the outlet side of the 

condenser fans to deflect warm discharge air upwards. This is particularly useful 

where units must face walls or other obstructions, and reduces problems associated 

with “Windmilling” of condenser fans due to strong winds in very exposed locations. 

Stacking Frames 

An optional purpose built frame is available, which allows condensing units to be 

stacked vertically, significantly reducing required external plant area, whilst providing 

sufficient space for correct air flow and service access. 

Operation on 60 Hz Power Supplies 

Units are available to special order, configured for operation on 60 Hz power supplies 

at either 460V/ 3 Phase and Neutral or 220V/ 3 Phase. 

Alternative Refrigerants 

Special units are available to operate with R134a, although performance will be 

affected (see R134a performance tables).
