Options and Accessories
Shell and Tube Condenser
Factory installed cleanable shell and tube condenser with
enhanced copper tube geometry . Provides removable,
epoxy coated, water plates to facilitate cleaning . Contact
factory for application parameters .
Motorized or Manual Water Isolation Valves
and Flush Ports
Factory installed water isolation valves and flush ports
provide isolation to the module for maintenance and
cleaning of evaporator and condenser heat exchangers
while adjacent modules continue normal operation . Both
motorized and manual valves include standard ¾” fill and
flush valves.
Motorized condenser water valves provide head pressure
regulation for low entering condenser water temperature
applications (less than 60°F).
Available choices include:
• (1) each motorized valve for evaporator and condenser
with (1) each manual valves for the evaporator and
condenser .
• (1) each motorized valve for the evaporator and (1) each
manual valve for the evaporator and (2) each manual
valves for the condenser .
• (2) each manual valves for the evaporator and
the condenser .
Hot Gas Bypass
For normal leaving chilled water temperature setpoint of
44 0 F, verify that the cut-in pressure is set at 31 .5 psig . For
water and glycol systems operating at lower leaving design
temperatures, cut-in pressure must be field adjusted at
approximately 4 psig above the equivalent water/glycol
temperature solution freeze point .
Pressure Differential Flow Sensor/Switch
Field installed to prevent operation of chiller without
sufficient water flow to evaporator and condenser.
Manual Strainers
Field installed strainers are external to the chiller bank to
increase efficiency and ensure long life of the modules.
A minimum 60 mesh stainless steel screen is required to
protect both the condenser and evaporator circuit .
Automatic CS Series Strainer Package
Field installed high quality stainless steel filtration systems
with minimum 60 mesh stainless steel screens . Available
options include pressure differential alarm and automatic
time flush.
Water Header Bypass
Factory installed to prevent deadheading the pump, a water
header bypass may be utilized and is mandatory when using
motorized valves .
