The CHX circulation heater is a compact unit used for heating gases or liquids. The fluid being heated is pumped through the coiled, seamless, 316 SS tubing which has been cast into an aluminum body and acts as the heat exchanger. The heat source for these heaters are either a replaceable Hi-Density Cartridge Heater or a Tubular Heating Element. Circulation heaters can come in single and dual tubing configurations.

Indirect heating is an important feature of our Cast-In Circulation Heaters. The fluid being heated never comes into contact directly the heat source. This can prevent thermal breakdown from overheating of a fluid and is an added safely benefit while heating combustible fluid. This feature also prevents contamination from being introduced into the fluid.
