Self Regulating Cables For Pipe Freeze Protection


The ELSR Self Regulating 230V heating cables provide an effective and affordable solution for the freeze protection of water pipes. They are suitable for use on metal and plastic pipes. Typical applications would be the protection of boiler condensate pipes, exposed water pipes in the home, farm buildings, stables, garages and lofts plus many other applications.

ELSR cables are supplied by the metre and can be cut to length on site minimising wastage. The ELSR trace heating range will not produce dangerous hot spots even when cables are touching or overlapping and the two power outputs within the range can be used when straight tracing pipes of between 15mm and 150mm in diameter.

To provide pipe freeze protection the ELSR cables are simply taped along the bottom of the pipe.

For plastic pipes we recommend the use of aluminium foil tape to provide better heat dispersion. For maximum protection, trace heated pipes should always be insulated. A connection kit using crimps and heat shrink insulation (kit 4) will be required per circuit. This kit includes components to produce a cold tail connection to the trace cable and seal the end.
