Pipe Freeze Protection

Safeguard pipes and ducts against freezing temperatures for a worry-free winter.

In cold environments, every pipe or vessel is subject to heat loss when its temperature becomes greater than the ambient temperature. Thermal insulation reduces the rate of heat loss but cannot prevent pipes from freezing or ensure efficient fluid flow.

What is the best way to melt ice on pipes?

Self-regulating and constant wattage cables provide the additional heat required to maintain the temperature of the pipe or conduit and proper flow of liquids. The main difference between both types of cables is that the self-regulating cable heat output varies depending on the outdoor temperatures. This feature maximizes efficiency and minimizes operating costs.

Warmup pipe heating cables and heat tape for pipes

Available in cut-to-length spools or plug-in kits, the Warmup self-regulating cables are ideal for indoor and outdoor pipe freeze protection, both for commercial and residential use. They are applicable on metal, PVC and ceramic pipes, sprinkler systems and sewer drains. They must run in physical contact along the length of a pipe. These cables are easy to install and control. The choice of cable and controls is dependent on the type of pipe being used, either metallic or plastic. You also need to calculate the heat loss in the pipe and adjust for any application deviations to determine which cable rating to use.

Warmup pipe heating cable is available in 3 different options: 3W/sqft, 5W/sqft or 8W/sqft.

A full range of controllers is available, guaranteeing the optimal solution for all outdoor heating.
