Product Description

Chromalox CWM constant wattage medium heating cable is a solution for industrial process temperature maintenance and freeze protection. CWM features a parallel heating core that produces uniform thermal output over its entire length System design only requires that you match the CWM cable thermal output to the heat loss of your piping system. CWM is flexible at most ambient temperatures and can be wrapped around piping and complex fittings. It is rugged, easy to monitor and maintain temperature, and has zero inrush at start-up.
