Circulation Heaters: Electric Circulation Heaters for Gases and Liquids

Circulation Heaters, Heaters, Controls And SensorsCirculation heaters are used when a pressurized, circulating fluid needs to be heated. A flanged immersion heater, or a screw plug immersion heater is inserted into a into a pressure vessel. This vessel may also be called a pipe body. The fluid passing though this circulation heater will raise to the desired temperature. This heating approach greatly enhances normal immersion heaters by offering a method to give you heat on demand. Many temperature control options give you can get the exact temperature control of the heated fluid.

Circulation heaters are ideal for pre-heating fuel oil, pumping viscosity and closed loop heat transfer systems or boosting the temperature of a gas. Standard ratings from 1.5 to 465 kW in various watt densities, sheath materials, chamber materials and pressure ratings.

Circulation heaters are compact and highly efficient heaters which may be used in forced or natural circulation systems to heat flowing gases or liquids. Screw plug immersion heater or flanged immersion heater, vessel, insulation, terminal enclosure, mounting brackets and inlet and outlet connections are included. Installation is simple with only basic wiring and piping connections required. An integral thermostat is included on Series 1, 2, 3, and 5 items. An installation a maintenance manual is supplied with each circulation heater.
