VL Series Portable Chillers, 2 to 40 Tons UGH021/0301
2.1 GENERAL
A. All process piping materials (such as hose, rigid piping, valves or
filters) used in process water piping circuitry must be rated for
100°F minimum temperature and 100 PSI minimum pressure.
B. All such materials must have the equivalent or larger diameter of
the particular process connection that length of process water
piping is connected to.
2.2 TO AND FROM PROCESS CONNECTIONS
(see figures 2.2A & 2.2B)
A. Connect the ‘TO PROCESS’ to the ‘water in’ manifold on the mold
or process.
B. Connect the ‘FROM PROCESS’ port to the ‘water out’ port on the
process manifold.
C. Process water piping circuitry should be designed to avoid an
excessive use of elbows and/or lengths of pipe or hose. If hose is
the material of choice, avoid tight twists or curls and excessive
lengths.
D. Valves and filters may be installed in the process water piping
circuitry to facilitate service and maintenance provided that such
devices maintain the full inside diameter of the process connection.
If installed, all such devices must be open and clean during unit
operation.
To process connection:
connect to “water in” on process manifold
From process connection:
connect to “water out” on process manifold
Condenser water in
connection:
connect to tower or city water supply
Condenser water out
connection:
connect to tower or city water return
Water supply connection:
(not shown on this unit)
connect to plant’s city water source
