RAYCHEM - electric heating systems

Chemelex Poland supplies heating systems and leak detection and localization systems for industry, construction, telecommunications, medical and other OEM sectors. Combining the operations and experience of Raychem, Pyrotenax, Hew-Therm and Tracer, it produces more diversified heating products than any other company in the world.

For the construction industry, the company offers electric heating systems based on Raychem's self-regulating technology widely used in commercial and residential construction: underfloor heating, protection of water pipes and sprinkler systems from freezing, de-icing of roofs and keeping gutters clear in winter, snow and ice removal on driveways, frames and sidewalks, maintenance of hot water temperature, leak detection and localization systems

SELF-REGULATING AND FIXED-RESISTANCE ELECTRIC FLOOR HEATING

Self-regulatingheating, unlike the commonly used fixed-resistance cables, automatically adjusts the heating output along the length of the cable to the ambient temperature by responding to external heat sources.

Due to its design using a polymer self-regulating element:

• SAFE: there is no possibility of heating above the marked maximum temperature (it does not overheat, it can be wrapped or crossed over safely)
• FAST INSTALLATION: laid in grooved insulation boards, it can be cut or extended at will during installation
• DURABLE: it is mechanically very durable.

When installing fixed-resistance systems, it is necessary to remember the need for a very precise layout of the room - kitchen or bathroom cabinets already at the stage of laying the floor. These systems heat at full power over the entire surface - in obscured areas the heat accumulates, so the system may fail (overheat the wire) or damage furniture or carpet on the floor. The self-regulating, intelligent RAYCHEM T2Red system detects such zones on its own and restricts heating, and changing the position of furniture in the future is not a problem. It is suitable for all types of floor coverings. Supplementing the system with aluminum-coated Reflecta insulation boards, you gain even heat distribution and minimal energy consumption, but this requires raising the floor level by 13 mm.

Fixed-resistance ducting also has its advantages. Factory-terminated, thin (3 mm thick), single-sided powered RAYCHEM QuickNet mats are ideal for renovations and refurbishments: they can be laid in a layer of tile adhesive and thus do not raise the floor level. The modern and intuitive thermostat has the option to remotely control the heating system via the free SENZ-WIFI mobile app. It can be controlled by voice - it is compatible with Amazon ^Alexa® and Google ^Assistant® smart home systems.

COMFORTABLE ACCESS IN WINTER - concrete, asphalt and paved driveways

Electric heating systems are an effective method of maintaining the surface of sidewalks, driveways and walkways in a condition that ensures trouble-free and safe movement. In particularly busy areas - parking lots, loading ramps, entrances to underground parking lots and even helicopter landing pads and airportsairports - durable and damage-resistant RAYCHEM EM2-XR self-regulating cables (300 W/m², 90 W/m at 0°C) are used. Thanks to self-regulating technology, these cables maintain the required temperature along the entire length of the heating circuit. They are very safe - they do not overheat even at the point of crossing.

EM2-MI mineral insulated high-temperature heating cables are the best solution for heating systems laid in hot asphalt. No other heating cable is so resistant to high temperatures and damage during installation.

RAYCHEM WinterGard-Mat heating mats with a power of 300 W/m² and a width of 60 cm work well for clearing snow from sidewalks and driving lanes covered with paving stones or asphalt. Pre-terminated RAYCHEM WinterGard-Cable fixed-resistance heating cables with a power of 25 W/m are laid on stairs, complex and irregularly shaped surfaces. The 2-wire cable design means only one cold wire to be connected to the power supply and controller.

PROTECTING PIPES FROM FREEZING

The task of electric heating systems is to protect water and sewage pipes from freezing, to protect installations supplying fuel oil or other liquids that change their physical and chemical properties under low temperatures, and to maintain the proper temperature of the pipeline. Using thermal insulation alone or increasing its thickness is often insufficient. WinterGard H622 self-regulating heating cable and halogen-free, low-smoke XL-Trace cables, combined with appropriate thermal insulation, will effectively protect water pipes, hydrant and sprinkler systems from freezing.

PROTECTION OF ROOFS AND GUTTERS AGAINST SNOW AND ICE ACCUMULATION

A complete self-regulating system with WinterGard H622 electric heating cable with28 W/m in snow/ice, 16 W/m in air at 5°C, provides reliable protection against damage in winter conditions. The heating cables are laid in a straight line along gutters and inside pipes. In box gutters or troughs, the cable may need to be laid in several lines. For fixing the cable, making branches, connecting the power supply and termination, there are accessories that are part of the respective system. It is possible to fully automate the operation - the EMDR-10 controller with a temperature and humidity sensor turns the system on automatically only if certain atmospheric conditions occur simultaneously.
