Air-Cooled Chiller Condensers

Air-cooled chillers use the surrounding air to cool the condenser. Install the chiller in an area where there is free passage of air for condensing and provisions for removal of heated air from the area. Do not locate air-cooled chillers in locations where steam, hot air, or fume exhausts can be drawn into the chiller.

Caution! Clean air-cooled condensers and filters frequently. Failure to do so results in reduced capacity, increased operating costs, and possible failure of the equipment. Cleaning instructions can be found in the Maintenance chapter of this manual

Normal maximum refrigerant condensing pressure with 95ºF (35ºC) air entering the condenser is 420 psi (2896 kPa).

Condensing Air Temperature. Our air-cooled portable chillers are designed to operate at a minimum condenser entering air temperature of approximately 75ºF (24ºC). Operation of the equipment at a lower condenser entering air temperature can cause the chiller to malfunction. For entering air temperatures below 75ºF (24°C), an optional fan motor speed control is available. We recommend maintaining a minimum 75ºF (24°C) ambient temperature.

Note:

For all chillers manufactured with Variable Frequency Drives the

 

voltage may vary up to 10% from the converter nominal voltage.

 

However, the phase-to-phase input voltage imbalance must not

 

exceed 3%. If the input voltage does have an imbalance from phase

 

to phase greater than 3% then a line reactor must be installed to

 

prevent faults within the VFD.

 

 

For remote condenser units, the maximum recommended motor

 

cable length between the VFD and the motor without output chokes

 

is 30 m (100 ft). With output chokes the motor cable length may be

 

extended to 65 m (195 ft).
