Options and Accessories
Motorized or Manual Water Isolation Valves
and Flush Ports
Factory installed water isolation valves and flush ports
shall 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. Note: All Heat Pump configurations require
motorized valves.
Motorized condenser water valves provide head pressure
regulation for low entering condenser water temperature
applications (less than 60°F) .
Available choices include:
• One each motorized valve for evaporator and
condenser with one each manual valves for the
evaporator and condenser .
• One each motorized valve for the evaporator and one
each manual valve for the evaporator and two each
manual valves for the condenser .
• Two each manual valves for the evaporator and
the condenser .
Hot Gas Bypass
Factory installed on both circuits allowing unit operation
below the minimum step of unloading .
Heat Pump
Factory installed reverse cycle heating and cooling operation
compatible with boiler/tower or geothermal systems .
Heat Recovery
Factory installed option providing hot water, as high as
135°F, while simultaneously producing chilled water for the
chiller system .
Pressure Differential Flow Sensor
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.
OSHPD Certification
Special seismic certification in accordance with
ICC-ES-AC-156 .
Water Header Bypass
To prevent deadheading the pump, a water header bypass
may be utilized and is mandatory when using motorized
valves .
