Heated hoses feature smooth and convoluted bores in stainless steel and Fluoropolymer cores, which are electrically heated for operation to 625ºF (329ºC). The hoses are flexible and can be operated in continuous movement conditions. The heating element is nickel alloy wire; spiral wound to extremely close tolerances, providing optimum temperature uniformity throughout the entire length. The heating element is insulated within multiple layers of high temperature insulation. Two thickness of thermal insulation are available with tough, extruded DSJM jacket for outdoor service or an abrasion resistant, braided polyester sleeve for indoor use. All hoses are supplied electrically and hydraulically complete, ready to use.
