Leaking roof in the spring associated with de-icing runoff to 90% of cases.
Clogged gutters and drains the ice during a thaw blocking the outflow of water of a roof.
Consequences - leaking roofs, facades of destruction on the upper floors of establishments.
The greatest danger posed to leaking roofs with curved inner corners, towers, attics and other decorative architectural criteria.
Cable heating gutters and drainage solves this problem and increases the duration of the roof, fixing brackets downpipes and gutters, reducing the mechanical stress from ice formation.
Heating cable is suitable for the following engineering areas: gutters
rainwater hopper and the region around them
valley - seam roof sections
catchment and drainage trays
eaves of roofs
Installation of cable heating gutters and drainage
Heating cable system consists of a drain the heating section (a self-regulating heating cable), the thermostat, cpanel with automatic protection systems and power distribution.
When installing heating cable system drainage is critical that the cable was globe place the spot that the water cascades. The complexity of installation is that, in Gutter system extra holes are not allowed, therefore the cable within the gutter is fixed in a special way. The cable is laid in the drain pipes, roof gutters and valleys in a significant of the plume. In storm sewer system, heating cables are routed beneath the soil the freezing point. Necessary to ensure the outflow of water in every aspect of drainage system.
Linear power heating cables in gutters should be 60-70 W / m (minimum of 20-40 W / m). If the channel is wider 150 mm, for normal weather conditions, taking the estimated capacity of 200 W/m2.
In the truth of a cool roof is plenty to lay cables only in the drain podium.
In circumstance of a warm roof falls further cable loops along the edge of the cover width of 0.3 - 0.5 m, with a specific power of 200 - 250 W/m2.
Heating water pipes. In private homes and businesses.
How good would stop being a thermal insulation pipe to completely eliminate the temperature loss is not.
Heating pipes and piping systems with heating cable to prevent such downfalls.
Principle of operation
Unlike conventional electric cables having low resistance, the heating cables are themselves load nevertheless the load is evenly distributed. Voltage applied for the heating cable, falls involved with it.
In order to recover heat losses along the pipeline or within the heating cable is laid, selected rrn order that the power per unit length when compared with or total the heat loss per meter of pipe.
With the perfect calculations and installation heat does not cause overheating of the cable assaulted heated toy.
For heating pipe from freezing are two basic types of heating cables: resistive and self-regulating.
Self-regulating cable is laid on the surface or inside pipes efficiently and effectively prevents them from abnormally cold. To save energy, set the thermostat turns up from the cable during a certain hot temperature.
The thermostat is usually set in the supposedly very cold place esophagus.
Self-regulating cable can be utilized to retain the temperature to 120 degrees of severity. Centigrade. This method of heating pipes are commonly used in various industrial processes and domestic, including heating of sewage pipes and tanks.
