Deionized Water
Stainless steel (316 SS minimum) or PVC plastic components must
be used with deionized water. Sterling recommends stainless steel
because of the temperature constraints with plastic.
3-7 Making Process Water Connections
Closed Circuit/Direct Injection
On the back of each unit, the connections are labeled appropriately.
For Direct Injection units connect the
TO PROCESS
hookup to the
entrance of the process and the
FROM PROCESS
hookup to
the exit of the process. Connect the
COOLING WATER
IN
to your plant water supply. Connect the
COOLING WATER
OUT
line to an open drain, or to the return line of
your central water system.
For Closed Circuit units make the connections as stated above, and
if there is a separate supply for the process and cooling make the
following connections. Connect the
PROCESS WATER
SUPPLY
hookup to the water source for the process. Connect the
PROCESS WATER VENT
hookup to return the water back to
the process source.
Make sure you carefully select the connecting lines and
connectors between the temperature control unit and the
process to suit the needs and requirements of your application.
If your unit has a maximum operating temperature of 250ºF
(121ºC), the connecting lines and connectors should have a
service rating of at least 250ºF (121ºC) and 150 psig (1,034.25
kPa/10.34 bars). If it has a maximum temperature of 300ºF
(149ºC), the lines and connectors should have a service rating
of at least 300ºF (149ºC) and 150 psig (1,034.25 kPa/10.34
bars).
TO PROCESS — 1½” NPT
This is the outlet for the tempered water leading to the process
being controlled.
