Spiral Silicone Heater for Small Diameter Pipes and Tubing



Need to heat small OD pipes and tubing? We have the solution right here- CHR Inc’s spiral silicone rubber heaters can be made in a variety of diameters and is ALREADY pre-formed to the proper diameter for your application.

This ensures proper contact and makes installation of our small tube heaters a breeze.

CHR Inc. designs and manufactures silicone rubber heaters for pipes and tubes, however, manufacturing techniques for our standard preformed heaters meant that for small diameter pipes the heater could only be manufactured in short lengths for rigid pipe work. Through continued product development, CHR can now offer the Spiral Wrap Heater range to suit flexible or rigid pipes
