## Summary description

Self-regulating heating cable DANFOSS DEVIFLEX 18T, length 29 m, rated 535 W at 230 V (MPN 140F1239).

Suitable for indoor and outdoor installations following manufacturer guidelines and electrical standards.

## Long description

Self-regulating heating cable DANFOSS DEVIFLEX 18T, length 29 m, rated at 535 W for 230 V supply, is designed for frost protection and temperature maintenance of pipes, gutters and roof edges. The cable changes its heat output in response to ambient temperature, increasing power when cold and reducing it as temperature rises to provide efficient protection without external thermostatic control. It is suitable for both indoor and outdoor applications when installed according to manufacturer instructions and applicable electrical standards.
Advantages
The DEVIFLEX 18T heating cable provides automatic adjustment of heat output based on ambient temperature, reducing risk of overheating and energy waste. Its self-regulating polymer core ensures localized heating where it is needed and lowers output where heat is already present. The cable is compatible with common mounting methods for pipes and gutters and can be cut to length at factory-terminated ends, simplifying installation planning. Constructed for exposure to outdoor conditions when correctly fixed and sealed, it supports consistent frost protection and temperature maintenance over long runs.
Suitable for
 Frost protection of water and waste pipes in buildings and outdoor runs
 Prevention of ice formation in gutters, downspouts and roof edges
 Temperature maintenance for process pipes and tanks in unheated spaces
 Spot heating of sections of piping where intermittent freezing may occur

How to use
Plan the heating run according to the pipe layout and thermal requirements, ensuring the cable length and power meet the area to be protected. Secure the cable along the pipe or gutter using appropriate fixing tapes, clips or mounting accessories recommended for heating cables, maintaining manufacturer-specified spacing and avoiding crossing or overlapping of the cable. Connect the cable to a protected power supply and, if required by local regulations, to an appropriate control or residual-current device. Follow all safety and electrical codes and the installation manual provided by the manufacturer to ensure safe and effective operation.
Usage recommendations
For reliable frost protection and efficient operation, insulate pipes where appropriate, avoid sharp bends or mechanical damage to the cable, and ensure end seal and power connections are performed or checked by a qualified electrician. Use compatible thermostats or control devices only if recommended for the specific installation and follow local electrical regulations for outdoor and wet-area installations.
