The Caloritech™ MX Pipe-Insert Immersion Heater is designed to provide uniformly distributed heat to storage vessels containing high viscosity liquids such as asphalt, molasses, tar, paint, glue, wax and oils without causing charring or coking. Units are installed in a suitable metal pipe contained inside the storage vessel (minimum 2" (51 mm) diameter), then heat is transferred safely from the heating element of the MX heater to the inner wall of the pipe by a combination of convection and radiation.
This heater is a safe, cost-effective and virtually maintenance-free solution that eliminates the need for high maintenance pumps or open flames, which may present a fire hazard, especially when the liquid being heated is flammable.
