2.0 COOLING CONFIGURATIONS
NOTE
All field-installed piping must comply with applicable local, state and federal codes.
Air-Cooled
Air-cooled unit piping is spun closed from
the factory and contain a nitrogen holding
charge. Each installation requires refrigerant
piping to a condenser.
Glycol-Cooled
Glycol-cooled units are factory-charged and
tested. Field-installed piping is required from the
unit to the drycooler and pump package.
Water-Cooled
Water-cooled units are factory-charged and
tested. Field-installed water piping is
required from the unit to the cooling tower.
GLYCOOL
GLYCOOL units are factory-charged and tested. Field-installed
piping is required from the unit to the drycooler and pump
package. An additional coil is included for use when fluid
t
emperatures are sufficiently low (below room temperature).
Cooling is provided by circulating cold glycol through this
s
econd coil, reducing compressor operation.
Dual-Cool
This system has all of the features of a compressorized
system, but adds a second cooling coil that is connected
to a source of chilled water. Cooling is provided by
circulating water through this second coil and reducing
compressor operation.
