Chiller/Heater and Description
Condenser
Evaporator
Source/Sink Heat Exchanger
Components Parts
The systems and subsystems of the PolyTherm
Simultaneous Chiller/Heater are configured and matched
to enhance performance and operating efficiency:
Frame
The PolyTherm Chiller/Heater frame is constructed of
formed sheet metal externally coated with white painted
finish and coated in black.
Cabinet
Cabinet panels are made of sheet metal externally coated
with white painted finish and internally coated in black. For
service, the cabinet enclosure is composed of easily
removable access panels. Access panels are removable
via stainless steel fasteners and retaining clips.

The condenser is a key chiller/heater component that receives refrigerant in the form
of gas from the compressor and changes it to liquid that absorbs the heat dissipated
by a cooling tower or ground source well system.
The brazed plate heat exchanger that is the evaporator is constructed as a plate
package of corrugated channel plates with filler material between each plate. The
filler material forms a brazed joint at every contact point on the plates, creating
complex channels. This allows fluid to come into close proximity, separated only by
channel plates, that enable heat from one fluid to be transferred to the other with
very high efficiency, but without gaskets and frame parts.
Models with the brazed plate heat exchanger are made of SAE Grade 316 stainless
steel and 99.9% copper brazing materials. Interconnecting headers are carbon steel.
Water quality must be verified and maintained by a professional in water treatment
and familiar with the materials of construction and operation of the equipment.

Strainers
A compact design suction diffuser with stainless steel 40
Mesh strainer is factory-installed on the branch line to each
evaporator, condenser and source/sink heat exchanger
inlet.
Isolation Valves
The strainer and flow switch are serviced by manually
closing the isolation valves on each evaporator, condenser
and source/sink heat exchanger branch line. With these
components independently isolated, they can be removed
or replaced as required and the strainer cleaned without
shutting down the fluid flow to the entire system while the
remaining modules to continue to operate.
Reversing Valve
Each module contains refrigeration valves on each
refrigeration circuit that open and close to allow the
