PHT-NF | constant wattage heating cable (Ex) 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

PHT2-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 the heating process of industrial pipes with high temperatures. Suitable for use in both, safe and hazardous areas, can withstand the temperature of up to +285 °C (when switched OFF).
PHT2-NF is a flexible and mechanically robust cable made with a fluoropolymer overjacket which is resistant to chemically hazardous environments (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 refineries, and food industry pipes.
