G. EVAPORATOR: The evaporator is a brazed plate heat
exchanger where the refrigerant liquid is allowed to
evaporate (boil off) to absorb heat (BTU) from the process
fluid. As the heat is absorbed, the process fluid is chilled.
J. Liquid receiver: (optional feature) located after the
condenser, this component receives and stores liquid
refrigerant leaving the condenser.
H. Service valves: These valves are located throughout the
system. Only a qualified refrigeration service technician
shall operate these valves.
6.3 UNIT OPTIONS
A. LOW FLOW BYPASS: If your process will experience lower
than design flow rates or intermittent flow, a low flow bypass
valve will be required.
B. OVERHEAD PIPING KIT: To avoid reservoir overflow
during shut down periods from overhead piping, The Factory
recommends the installation of an overhead piping kit. The
overhead piping kit consists of a full line size solenoid
valve in the “from process” line that is interlocked with the
pump and a check valve (single direction valve) in the “to
process” line.
C. PROCESS LINE SHUT OFF VALVES: These valves
are full size ball valves installed on the “to” and “from”
process lines at the exit of the chiller. These valves can
be used to adjust the process flow rate and to shut off the
flow rate to isolate the chiller.
D. E-STOP BUTTON: The Emergency stop button is a
mushroom type button which will shut down all chiller
operations when engaged.
E. NON-FUSED OR FUSED DISCONNECT SWITCH: On
board disconnect switch provides a convenient location
for isolating all electric power to the chiller.
F. AUDIBLE AND OR VISUAL ALARM: Alarms indicate
out-of-spec operating conditions. There are two types of
alarms:
Audible Alarm: A simple buzzer alarm emits a
loud alarm.
Visual Alarm: Emits an audible sound and flashes a beacon.
G. CONDENSER SCREEN: Optional for air-cooled models only. The condenser screen is a
filter for the air-cooled condenser to prevent air borne solids and debris from clogging the
