Roof Applications

ICE- AND SNOW MELTING ON ROOFS

dsid2_2

Ice and snow in gutters, down pipes, valleys and other roof constructions, often cause damage on buildings. Damage of this kind does not only apply to buildings but also people can be injured and property damaged by down-falling snow or ice, when the dewatering system of the roof does not work satisfactorily.

In some weathers, for example at midday thaw, tee stoppings are often formed in gutters and down pipes. This means that the melted snow and ice from the roof flood the gutters and icicles are formed. When these icicles fall down they can cause severe injury and damage both on people and material.

Pools remaining on the roof are often cause to leakage and damage due to moisture.

By applying heating cables the gutters, box gutters, valleys, down pipes and other construction details of the roof, you eliminate the damage risk by frozen over dewatering systems.

HOW DOES THE DE-ICING APPLICATIONS OF VÄRMEKABELTEKNIK OPERATE?

These systems are based on heating cables and when the cables are voltage-fed and warm the snow and ice around will melt.

The cables can be applied in many a different ways depending on the construction of the roof and the required operation.

HOW ABOUT THE ENERGY CONSUMPTION?

VÄRMEKABELTEKNIK has a large-scale programme for control in order to optimize the energy consumption to a minimum.

Air and roof sensors in combination with moisture sensors makes it possible to design a very efficient control, since the cables operate only when required.

EARTH-LEAKAGE-CIRCUIT BREAKER (ELCB)

All roof applications for 230V should, according to the safety regulations, be equipped with earth-leakage-circuit breakers (30 mA).
