1.1.3 Split Systems
Each air-cooled split system consists of an evaporator section and one of the following condensing
units.
Prop Fan Air-Cooled
Prop Fan units include scroll compressor, condenser coil, prop fan, high pressure switch, hot gas
bypass and Liebert Lee-Temp head pressure control. Unit is designed for outdoor location.
Centrifugal Fan Air-Cooled
Centrifugal Fan units include scroll compressor, condenser coil, centrifugal blower assembly,
high-pressure switch, hot gas bypass and Liebert Lee-Temp head pressure control. Unit must be
mounted indoors. Duct flanges are optional.
Water-Cooled
Each water-cooled split system consists of an evaporator section and a water/glycol condensing unit,
which includes scroll compressor, coaxial condenser, water regulating valve, hot gas bypass and
high-pressure switch. Design pressure is 150 psi (1034 kPa) as standard and 350 psi (2413 kPa) as
optional.
Glycol-Cooled
Each glycol-cooled split system consists of an evaporator section, a water/glycol condensing unit (as
described above), a pump package, and a 95°F (35°C) design ambient drycooler.
