Constructed using a spiral heater element encased between two layers of silicone rubber, spiral heaters are well suited to fit curved or straight pipework. The standard range is suitable to suit ¼” (6.35mm) outer diameter and can be supplied in six different lengths. With a maximum operating temperature of 200°C and the option to add a variety of temperature sensors, spiral heaters provide an ideal solution to heating pipes in many applications.


Spiral heaters have good resistance to the following; weather & ageing, fungus & bacteria, acetone, alcohol, formic acid, brake fluid, acetic acid, greases, hydrochloric acid 10%, sulphuric Acid 10%, waxes and plasticisers. In addition to this the heaters have adequate gas permeability and good steam resistance up 130°C and 2.5 Bar respectively.

Health & Safety

Spiral heaters are intended for use in industrial electric apparatus. They correspond to the BS EN 60335-1:2012. The heater has to be operated in accordance with these standard and regulations and should be installed on an electrical system protected by a residual current circuit breaker.
