US firm Durex Industries, a leading designer and manufacturer of heaters, temperature sensors, controls and systems, develops their Elastic Wrap Heater (EWH) technology.
Elastic Wrap Heaters are used in applications that require heating for freeze protection or to prevent condensation. Based on silicone rubber heater technology, lengths of the heater are coiled similar to a telephone cord. The elasticity of the cord facilitates easy wrapping of the heater around pipes, tubes and fittings. The moulded end protector snaps around a pipe to provide structural support for the lead wires. The 120 and 240 VAC heaters are available in widths up to 1.0 inch (25.4 mm) and straight lengths up to 125 inches (3175 mm).
The technology exhibits ease of installation and removal, along with the inert characteristics of silicone rubber, according to the Illinois-based firm.
