Self-Regulating Heating Cables – FailSafe Ultimo (FSUw)
The FSUw is a self-regulating heating cable, ideal for frost protection and temperature maintenance of pipes and tanks. It can be cut to length directly on-site, precisely adapting to needs without requiring complex design calculations.
This self-regulating heating cable automatically adjusts its output power based on the pipe temperature. It does not overheat or burn, even in case of overlapping, making it particularly safe and reliable.
FailSafe Ultimo is available with a corrosion-resistant fluoropolymer outer jacket (FSUw-NF).
This self-regulating heating cable complies with DNV, EAC, ATEX, IEC, IECEx, and CE standards, ensuring optimal safety and reliability in the most demanding environments.
