Preformed Heaters

Pre-formed Silicone heaters are versatile heating elements that can conform to the diameters of various pipes and vessels. These silicone heating elements can retain their form without any additional attachments in some cases, making them convenient to install and remove.

For applications that require more efficient contact, we can also provide separate fixing straps that secure the heaters without damaging the pipes or vessels. This type of heater is highly adaptable and can be customized to meet the specific needs of different pipe/vessel heating applications.

Our Pre-formed heaters can be designed to bespoke diameters, dimensions and supplied with various fixing methods. Customisable to suit applications with a broad range of voltages and wattages. In addition, sensors, limiters, and thermal fuses can be integrated to allow control and operation in a wide range of temperatures. Contact us to discuss the needs and specifications of your custom pre-formed heaters.
