Frost protection of drains and gatings.
Ice formation in the drains prevents the transportation of melting water. In connection with ramps, inclines or low terrain driveways it is common to install a drain system to drain surface and ground water.
Most of the year the drain system works perfectly, but in the winter under conditions with changing temperatures around the freezing point can cause freezing of the drain systems. And the ice formations are often substantial.
These problems can be avoided by installing 30-50 W/m Deviflex™ heating cables in drain pipes and gratings, controlled by a Devireg thermostat.
