General Information
Unit Description
The RTWD units are helical-rotary type, water-cooled,
liquid chillers, designed for installation indoors. The units
have 2 independent refrigerant circuits, with one
compressor per circuit. The RTWD units are packaged with
an evaporator and condenser
Note: Each RTWD unit is a completely assembled,
hermetic package that is factory-piped, wired,
leaktested, dehydrated, charged and tested for
proper control operations prior to shipment. The
chilled water inlet and outlet openings are covered
for shipment.
The RTWD series features Trane's exclusive Adaptive
Control logic with chiller controls. It monitors the control
variables that govern the operation of the chiller unit.
Adaptive Control logic can correct these variables, when
necessary, to optimize operational efficiencies, avoid chiller
shutdown, and keep producing chilled water.
Compressor unloaders are solenoid actuated. Each
refrigerant circuit is provided with filter, sight glass,
electronic expansion valve, and charging valves on the
RTWD.
The evaporator and condenser are manufactured in
accordance with ASME standards. The evaporator is fully
insulated. Both evaporator and condenser are equipped
with water drain and vent connections.
Accessory/Options Information
Check all the accessories and loose parts which are
shipped with the unit against the original order. Included in
these items will be water vessel drain plugs, rigging
diagrams, electrical diagrams, and service literature, which
are placed inside the control panel and/or starter panel for
shipment. Also check for optional components, such as
flow switches and isolators.
