Temperature Control Unit | Oil Circulating | Heating and Cooling

RK-27100HC
  • 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.

Features

Process Pump

  • 5 HP provides 70 GPM at 28 PSI
  • 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

  • 27 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
  • Tank is used for fluid storage during shut down
  • Vent protects against unit over pressurization
