Insertion Heaters

Home / / Insertion Heaters


Assemblies of mineral insulated heating elements, or open wire resistance coils, fitted to stainless steel, ceramic, or mica support disks, coupled by central rod or strip channel fixtures. They are designed to fit into drywell tubes in tanks and vessels, and allow withdrawal and replacement without drain-down. Manufactured to wattage and voltage to suit each individual application. Made with flying leads, terminal boxes, and front mounting flanges if required. Ceramic and mica types are flexible, to allow fitting in restricted spaces.


Used in heating liquids and semi-solids, for temperature maintenance or raising, in vessels where draining is not possible or desirable. These heaters are robust and long lasting, and suitable for many applications, but especially those involving viscous substances, such as tar, bitumen, asphalt, heavy oils, molasses, etc.
