Factory charged and sealed, the water cooled con- densing unit is ready to be installed quickly and eas- ily. The counter-flow coaxial condenser with two-way or three-way regulating valve designed for 150 psi (1034.3 kPa) is matched to the heat rejection require- ments of the compressor for a variety of flow rates and fluid temperatures.

Condensing unit has a hot gas bypass standard fea- ture that bypasses hot gas around the compressor directly to the suction side of the compressor to pro- vide capacity control and reduce compressor cycling. System includes liquid injection valve to maintain proper suction superheat.

The Liebert manufactured Fan Speed Control dry- cooler is constructed of aluminum and features cop- per tubes and aluminum fin design. It is low profile, propeller fan type and provides quiet, trouble free heat rejection. The drycooler features a variable speed fan motor and a specially engineered solid state fan speed transducer. The transducer senses the temperature of the leaving glycol and modulates the speed of the fan to maintain proper glycol tem- peratures. An integral, factory-wired and tested con- trol panel reduces installation time.

The glycol system includes a matching centrifugal glycol pump. It is mounted in a vented, weatherproof enclosure.
