HEI/Calorflex Industrial heaters can quickly transfer heat to liquids, gases and solids. The tubular heater utilizes conduction, convection and radiant methods for immersion and air heating. It comes in a range of shapes – from circular to triangular & vertical or horizontal configurations. The models are often custom formed to accommodate specific applications. Our Tubular heaters provide an excellent solution, giving you a clean and efficient manner of maintaining an ambient temperature at just the right level. They have many advantages compared to other outbuilding heating solutions such as paraffin stoves or electric fan heaters. Tubular air heaters (or preheaters) are vital pieces of equipment when you're trying to keep thermal efficiency as high as possible. Tubular Heaters are Highly versatile and economical, electric tubular heating elements are applied in virtually every conceivable type of heating application. Our manufactured tubular heaters are also used for radiant heating in open air or vacuum atmospheres. The heating elements can be cast into or clamped onto metal to form heated parts. We offer a wide selection of standard designs, or tubular heating elements can be custom designed for your requirements. The design & engineering team are available to assist in specifying the proper electric tubular heater configuration.
