Circulation Heaters
Circulation heaters are packaged units consisting of a screwplug or flanged immersion heater mounted in a thermally insulated heating chamber for efficient heating of a flowing medium by in-line or side-arm operation. Thermocouple sensors can be provided to connect to most any controller. Select from many terminal enclosures, sheath and vessel materials, flanged connections, and controls.

Common Types
Clean Water Circulation Heaters
Clean Water Heaters are ideal for heating municipal water for industrial washing and rinsing processes. Sturdy 0.475" diameter copper sheath elements provide superior strength and rigidity. Heater elements utilize high quality resistance wire for coil construction. All stock and assembly stock heaters come with mechanical AR thermostats. These thermostats are suitable for most applications. Explosion-resistant and liquid-tight thermostats are provided on E2/E3 and E4 units, respectively. Other applications include indirect heating of viscous liquids and temperature maintenance of storage tanks.
Fuel Oil Circulation Heaters
Light and Medium Weight Oil Heaters are ideal for temperature maintenance and for improving flow characteristics of oils. Fuel and gas heaters are also used for Heat Transfer Oils. Heavy or Fuel Oil Heaters will reduce the viscosity, thereby improving flow and process efficiency. Preheating fuel oils provides better atomization at the burners and allows the use of lower grade fuel oils.
Steam, Air and Gas Circulation Heaters
Steam, air and gas circulation heaters provide a cost effective means for heating air and common industrial gases such as Argon, Helium and Nitrogen as well as gaseous mixtures for a wide variety of industrial processes. Heater elements and a Stainless steel vessel enhance safe operation to nearly 1400°F outlet gas temperature in air, gas, or steam superheating applications. They can also be used to increase the enthalpy and quality of steam. Smaller units can be used to make up line losses in steam generating and distribution systems.
