FSU-NF | self-limiting heating cable (Ex) up to +250°C

FSU-NF is an industrial grade self-regulating heating cable that can be used for freeze protection or temperature maintenance of pipework and vessels. It can be cut-to-length at the site to match exact piping lengths without any complicated design considerations.

General details

FSU-NF is a self-limiting heating cable of 15 W/m, 30 W/m, 45 W/m, 60 W/m and 75 W/m output for heating and frost protection high-temperature industrial pipes. It can be installed in both safe and hazardous (Ex) areas. The cable produced with nanotechnologies to ensure long-lasting benefits withstands the temperature of up to 250 °c (when switched On or OFF).
FSU-NF cable is made of a fluoropolymer over jacket resistant to the chemically hazardous environment (that of bitumen, oil products, food and industrial oils and other chemical products production).

Installation: for frost protection and temperature maintenance of industrial pipes, oil terminals and refinery, and food industry pipes.
