Home > Products > CM 2/1 Cable Monitoring and Control

The Problem

• Centralized control and monitoring of the heat trace system.
• Real time, automatic monitoring of each heating cable's electrical functions.
• Need to dramatically reduce maintenance costs.
• Need to reduce problem response time.

Solution

The CM-1 and CM-2 units have been designed for separate or combined use. When combined, all of the functions are controlled and reported through the CM-2 control head, totally integrating the operation of the cable monitoring functions of the CM-2 and the temperature control capabilities of the CM-2.
