Application

Maintains water flow in gutters and drains pipes.

Description

The Raychem self-regulating snow melting system maintains water flow in gutters and drains pipes and provides a path whereby melting ice and snow can drain safely off the roof, along the gutter and down the drain pipe.


System components:

  • Ambient and moisture sensors.
  • Fixing bracket.
  • Control unit.
  • Residual current device (RCD 30 mA) circuit-breaker (C type).
  • Connection RayClic CE-02.
  • Heating cable.
  • End seal.


Features and benefits:

  • The self-regulating cable can be closely spaced in gutters without the risk for overheating or burn-outs. There is a cable for each type of roof material.
  • The system saves energy by automatically increasing its heat output in icy water and decreasing its output in dry air. The smart EMDR-10 control unit only switches the heating cable on when necessary, after the detection of both low temperature and moisture.
  • 25 year cable life expectancy.

Application

Freeze protection.

Heat emitters

Cable length:

  • The cable length is determined by the drainpipe length plus 1 m per connection and 1 m in the soil (frost line).
  • The heating cable should be installed in a straight line in the gutter.
  • The cable lengths should be adjusted according to the geographical situation and the gutters.
  • More than one cable should be laid in wide valley, parapet or box gutters.


Electrical protection:

  • The total length of heating cable determines the number and size of the fuses.
  • Residual current device (RCD): 30 mA required, maximum 500 m heating cable per RCD.
  • Installation according to local regulations uses C type circuit breakers.
  • The power connections must be carried out by an approved electrical installer.
  • Consult technical literature for further details.
