In cold conditions thermal insulation alone cannot fully protect water and drainpipes from freezing. Harsh weather may also cause fuel lines to clog. To safeguard water pipes and fuel lines from cold-temperature damage, PWLThermotex offers SRF self-regulating heating cables. These heating cables prevent plastic and metal pipes from freezing, and maintain correct flow temperature for fuel oil. SRF heating cables keep total operating and total installed costs down. The energy-efficient heating cables adjust their power output in response to ambient temperatures along water pipes, fire mains, sprinkler systems and fuel oil lines. Easy to install, they can be cut to length on site and overlapped at valves, flanges and pumps.
Our SRF frost protection cables are manufactured and designed using a self-regulating conductive core protected by a moisture-resistant barrier. It uses both a standard modified polyolefin jacket and a modified polyolefin outer jacket connected by tinned-copper braiding. Intended as a single run installation, our solution withstands maximum exposure temperatures of up to 85ºc (intermittent) and minimum installation temperatures of -60ºc.
We, at Thermotex, are able to manufacture our frost protection applications in multiple configurations and provide various accessories and bespoke solutions to suit a specific arrangement. FM approved (T5) classification heater tape is available upon request and Fluoropolymer outer jackets are Thermotex recommended for applications where increased chemical resistance is required. Other hazardous area classifications include CE marked, IECEx and GOST approval.
