Tubular Heaters

​Proheat tubular heaters are used in multiple applications, including drums, dies, cylinders, injections, holding tanks, and blow molding machines. They perform exceptional heat transfer by conduction, convection, or radiation in order to heat liquids, gases, air, and surfaces. Common tubular heater applications include hot tubs, furnaces, ducts, food service equipment, ovens, and epoxy curing.

​Tubular heaters can be custom-formed to meet specific requirements and come in a variety of lengths and sizes. Popular tubular heater elements include straight tubular heaters, hair pin tubular heaters, and finned tubular heaters.
