ROOF ULTRA – 30 W/M

Antifreeze, ice and snow melting on the roof, gutters and drainpipes. The drainage of meltwater prevents damage due to frost and the formation of dangerous icicles.

• Can be shortened to desired length on-site.
• No issues regarding starting current as opposed to selflimiting cables and always the same output/power consumption no matter the ambient  temperature.
• Built-in cold cable can be directly connected to thermostat.
• Easy connection to terminals.
• Elastoprene – UV-resistant.
• Temperature range from -40°C to +120°C.
• Very flexible and robust and thus very easy to install. No reduction of total output over time.
• High-quality materials provide for long service life.
• Range of outputs from 15 W/m to 90 W

The parallel resistive heating cable is a resistance cable with a constant output. The outer insulation of the cable is made of elastoprene which is specially designed for the protection of roofs, gutters and downspouts against frost. Elastoprene is very UV resistant, robust and flexible and therefore very easy to install.

The cable consists of short heating units placed one after another. The distance between the units is 60 cm. At the contact points, the built-in heating wire meets phase and neutral, which enables shortening of the cable to the desired length. The contact points can be seen and felt on the outer insulation of the cable. From the end of the cable to the first contact point, no heating is produced. The maximum length of the cold end therefore equals the distance between the contact points, i.e. 60 cm, and this part of the cable can be connected directly to a terminal or terminal block. The heating capacity of the cable does not change when the cable is shortened. Since the cable is a resistance cable, it does not require a large amount of starting current.

As a result, it is possible to install very long cables, which is one of the benefits of the parallel resistive cable. The maximum length of the cable is always the same, no matter the temperature conditions under which the cable is installed. Depending on the output of the cable, the maximum installation length is 100 – 150 m. The output is not reduced over the years as we know it from the self-limiting heating cable, and this means greater reliability and a longer service life. Furthermore, this high quality cable is made of the best raw materials – see the drawing of the structure. The cable should be connected to a thermostat for monitoring and, not least, energy-optimised operation. Do not cross or overlap the cable during installation.
