|Circulation heaters, also known as “inline heaters” have been used in many applications. They are packaged units consisting of a screw plug 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.
Applications include Water Heating, Freeze Protection, Heat Transfer Oil Heating, Fuel Oil Heating, Steam, Air, and Gas Heating and others.
Industrial circulation heaters come in a range of watt densities. Watt densities are specifically designed for the medium they will heat. The required wattage to heat the oil or water is highly correlated to the flow rate (in GPM).
PMJ offers the broadest selection of stocked Immersion Heaters in the industry. Industrial immersion heaters are designed for direct contact heating of water, oils, viscous materials, solvents, process solutions and gases for many industrial heat applications. Since all heat is generated within the liquid or process, virtually 100% energy efficiency is achieved. Various temperature control options permit very tight process temperature control. Basic mounting options of threaded screw plug connections, flanges, or simple over-the-side designs facilitate customer installation. A large selection of designs is available from stock for immediate delivery. Products are available for heating any fluid; from plain water to corrosive solutions, highly viscous oils, and for many specialized applications such as high pressure and hazardous areas. Custom engineered designs are also routinely manufactured by PMJ.
