Product Overview
The Hot Oil temperature control units are designed to control the temperature of your process by circulating a high temperature heat transfer fluid through the process.
This temperature control unit can be used in a wide range of industrial processes including; plastics, rubber, die casting as well as many other manufacturing processes that require a process fluid temperature range between 100˚F - 500°F.
A high flow pump circulates the fluid at the appropriate temperature to maintain a precise fluid and process temperature.
Depending on whether the process needs to be heated or cooled the circulated fluid is either heated by the electric heater or cooled indirectly via the available water
to oil heat exchanger.
These units are designed with the highest quality components and can be customized to meet your specific requirements.

Do not use Mobiltherm 603.
Full load amps are higher than run load amps and must be used for sizing disconnects and supply wiring. Not for construction. Consult factory for power requirements of unit as configured and on selected options.
Low pressure, high flow centrifugal pump
eliminates high pressure safety concerns
Custom designed pump casings produce higher
flow with less horsepower
Water cooled pump seal maintains seal integrity
and lengthens service life
Seal cooling is provided by facility water
circulated within a cast jacket surrounding
the seal area
Process Connections
Female NPT fittings standard on all process connections
To and From Process connections supplied with shut off valves
Supplied with manual process fluid purge system allowing purging of the process for storage within the unit expansion tank. Requires low pressure compressed air source for operation.
Cabinetry & Frame
Stainless steel enclosure panels
Hinged electrical panel
Portable, on casters
Heater
12 kW
Flange mounted reduces leak potential
Vertically mounted for easy servicing
Uses a steel heater sheath for a long life at
high fluid temperatures
Cooling Circuit
A water to oil heat exchanger is used to cool the circulated fluid
Cooling water flow to the heat exchanger is regulated by a solenoid valve controlled by the microprocessor control instrument
Expansion Tank & Reservoir
Large capacity expansion tank allows roomfor thermal expansion
