GUTTER HEATING Product overview and technical data.

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

High efficiency

Rapid de-icing

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

Voltage: 230 V
Special outputs: 30 W/m
Nominal temperature: 105°C
Min. installation temperature: - 50°C
Max. single legth: 70 m
Min. bending radius: 25 mm
Dimensions: 10 x 7 mm
Weight: 97 g/lfm
Certification: CE compliant

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

CASE STUDY

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.
