ETHERMA eTRACE-30CT – CONSTANT HEATING TRACE FOR ROOF AND BOX DRAINS
The eTRACE-30CT constant heating trace is ideal for heating box drains. The heating trace is soft-elastic made of insulated, flexible trace element with constant power output. Design according to VDE regulation with soldered resistance wire. It lies flat in the gutter and reliably prevents tunnel formation of snow. In order to achieve the lowest possible operating costs for gutter heating, it is necessary that the heating trace has optimum contact with the guteer. Constant heating traces are used in particular in metal box drains.
Highly elastic - no inherent rigidity
Excellent heat transfer
No high switch-on current
Can be cut to length every 60 cm, can also be custom-made at the factory
Fast, simple installation
Needs connection from one side only
UV and ozone resistant
Resistant to acids and base
|Special outputs:||30 W/m|
|Min. installation temperature:||- 50°C|
|Max. single legth:||70 m|
|Min. bending radius:||25 mm|
|Dimensions:||10 x 7 mm|
For standard gutters, 30W/m are installed up to 1000m above sea level. For box drains, the power output per metre is determined as follows.
> Width of the gutter (in m) x 250 W
> For a gutter with a width of 24 cm this means:
0.24 x 250 = 60 Watt
This corresponds to 2 heating traces of 30 W/m each
NEW AIRPORT TOWER, SALZBURG GUTTER HEATING
THE INITIAL SITUATION
The new tower at Salzburg airport also required an ETHERMA custom solution. Icicles formed along the entire curvature of the building, and thus posed a constant danger to airport workers.
THE ETHERMA SOLUTION
In order to prevent the build-up of icicles and the danger that they posed, tracks with ETHERMA eTRACE-30CT constant heating strips were laid beneath the sheet metal. The melted water was then directed via an internal gutter into the inside of the building.
