Silicone Heaters

Heatfast insulation foam type silicone heaters provide high efficiency thermal insulation to help reduce heat loss from pipes, ‘T’ sections, flanges, valves and pumps.

Bespoke pieces to suit ‘T’ sections, flanges and valves are available as well as straight sections up to 1 metre in length, in standard sizes to suit pipe diameters from 38.1 mm (1.5”) to 152.4 mm (6”).

Silicone rubber products have a high resistance to UV light, oxidation, corona discharge, cosmic radiation, ozone and general weathering.

Typical applications for these silicone heaters include: frost protection, industrial catering, anti-condensation, GRP pipe curing systems, composite repair of aircraft, environmental control or electronics, heat loss prevention and temperature maintenance.

For complete heat tracing of complex mechanical services and pipework systems in both industrial and hazardous area locations we can provide a full range of heating cables and trace heating systems.
