Pentair expands its product bag: 40 years of Raychem self-regulating heat-tracing technology
“Since the introduction of heat-tracing technology in 1974 until today, Raychem has remained at the forefront of innovation in industrial heat management,” comments Martin Lee, Global Marketing Director at Pentair. “We are very proud of this achievement and wanted to celebrate Raychem’s remarkable heritage in a special way. Our Pole Position campaign is fun, exciting and simply the right way to step into the future with our partners, customers and Raychem fans around the world.”
Pentair is a global leader in industrial heat-tracing, with solutions for applications including freeze protection, temperature maintenance and heat-up to 700°C or more.
Recently they launched enhanced versions of Raychem XTV and KTV self-regulating heat-tracing cables. The new heating cables are suitable for exposure to 250°C, whereas previous versions were limited to 215°C.
At the same time, Pentair brings the ‘system approach’ testing methodology into compliance with the latest revision of the international standard IEEE 515. This provides significant improvements to maximum sheath temperatures of Raychem’s XTV and KTV cables when using stabilised designs in hazardous locations. As a result, they can now be used for applications with higher maximum pipe temperatures (process or runaway temperature or control-limited set point), within the same temperature classification. This will simplify the design and installation considerably on projects, in particular for applications with temperature class T3 (200°C).
Next to that, Pentair has launched a new electronic surface sensing thermostat for hazardous areas. The Raychem ETS-05 thermostat provides accurate temperature control and monitoring for heat-tracing installations. It provides an increased maximum current load (32A), bigger connection terminals (6 mm2), a broader temperature control range, local LED indications and an additional fail-safe option.
The increased size of the terminals to 6 mm2 enables power and heat-tracing cables to be connected directly. This reduces the cost for plant owners as it will no longer be necessary to use junction boxes.
Raychem ETS-05 is available in two versions: the ETS-05-L2-E up to 199°C, and the ETS-05-H2-E for temperatures up to 499°C. Both come with a maximum nominal current of 32 Amps for longer circuits.
The thermostat has a configurable failsafe mode (power on/off). The local LED indicator shows the status of the device itself and whether the heat-tracing cable is switched on or off. In case of sensor failure, the thermostat will switch to an on or off state, depending on the user’s requirement. Raychem ETS-05 is fully compliant with ATEX and IECEx requirements for use in ZONES 1, 2, 21 and 22.
A new public version of Pentair’s design software with the above enhancements (TraceCalc Pro 2.7) is now available and can be downloaded from the Pentair website.
Raychem, the inventor of self-regulating heat-tracing cables, continues to be the global reference for energy-efficient heat-tracing designs with superior performance and highest reliability.
