PHT-NF | constant power heating cable up to +285°C

PHT-NF is a parallel circuit, mineral insulated, constant power heating cable designed for frost protection and heating process of industrial pipes with high temperature.

General details

PHT-NF is a parallel circuit, mineral insulated, cut-to-length, constant power heating cable of 10 W/m, 30 W/m, 50 W/m and 70 W/m output. It is designed for frost protection and heating process of industrial pipes with high temperature. Suitable for use in both, safe and hazardous areas, can withstand the temperature of up to +285 °C (when switched off).
PHT-NF is a flexible and mechanically robust cable made of fluoropolymer overjacket which is resistant to the chemically hazardous environment (that of bitumen, oil products, food and industrial oils and other chemical products production). Available in 200-300 m reel.

Installation: the cable is designed for temperature maintenance of industrial pipes, oil terminals and refinery, and food industry pipes.
