Installation Instructions
General Information
The Chromalox Heat Transfer Unit is a thoroughly engi-
neered, pretested package, designed to give years of
service, virtually maintenance free if properly installed.
The MWS series can operate up to 300˚F (149˚C) (de-
pending upon heat transfer fluid properties and unit
configuration) with features that comply with the Na-
tional Electrical Code.
Common to all models: electronic process controller,
air-cooled mechanical seal, chamber insulation, dis-
charge pressure gauge, steel heater sheath, cast iron,
centrifugal pump; power requirements 240 to 600 volts,
3 phase, 60 cycles, 50 thru 600kW.
In hazardous areas, pipe surfaces could
achieve temperatures high enough to cause
auto-ignition of the hazardous material pres-
ent. Consult Article 500 of the National Elec-
tric Code for further information on the maxi-
mum allowable temperature for a specific
application.
