Circulation heaters are an ideal way to quickly and easily set up a self-contained electrical heating system in a commercial, industrial, or military facility. A circulation heater comes with heater elements, a pressurized receptacle with insulation, a terminal housing, mounting features, and threaded inlet/outlet connections. A circulation heating system can be engineered to warm air, gases, or fluids.

The heating source for a circulation heater can be a screw plug immersion heater or a flanged immersion heater. These circulating process heaters are efficient, because the heat created by the immersion elements is instantaneously dispersed into the process air, gas, or water with a minimal amount of heat loss occurring within the insulated vessel.

Setting up a circulation heater is relatively easy–just hook up the electrical screw terminals located inside the terminal housing, screw the necessary pipes into place at the inlet and outlet locations, and dial in your desired process temperature on the thermostat (if supplied with your circulation heater).


Typical Applications for a Circulation Heater

Circulation heaters can be built to provide controlled heating for these materials and requirements: heat transfer fluids used in plastic molding and for maintaining heat sensitive materials, heating and/or preheating fuels and oils, tap water or process water used for cleaning and cooking, and increasing or maintaining process air.
Which One is Right for You?

Specifying the right Circulation Heater for your Process

A circulation heater will last a long time with almost no problems–as long as the sheath material, watt density, and process temperature specified is appropriately matched with the substance being heated.

Particular attention needs to be given to these items:

1. Select an optimum heater sheath material for your particular process.

2. Take into account the operating temperature recommendations for the material being heated, while maintaining an appropriate maximum watt density for the heater.

3. Verify the flange material is suitable for the high limits of your process with regard to pressure and temperature.

4. Choose durable terminal protection that will safeguard the electrical wire connections and keep your work environment safe.

5. Compare the container size and the likelihood of attaining a uniform temperature within the container. Use this information to determine if several smaller heaters would be better than one large circulation heater for the process.

6. Work with a qualified supplier, like Jobco Inc., by calling 479-424-1300 to get the right heater for your heating needs.
