pipe heater

Kawai’s pipe heater is specially designed for the heating of pipes, valves, and pumps. The heater exterior is wrapped with insulating material, which keeps heat dispersion down to a minimum, reducing energy usage and preventing burns when working.

The heater can be attached and removed easily with snap buttons or Velcro straps, and a connector can be used to connect multiple heaters. It boasts a superior level of heat uniformity with a ±5 ºF (±5ºC) variation at 140ºF (60ºC). Use this heater to warm gases, control the fluidity of liquids, and for other purposes.
