Outdoor Underground Heating System
TruHeat’s Amorphous HeatWAVE is a next generation outdoor heating system, specifically designed to heat all underground applications. Based on our unique patented amorphous metal alloy technology, the HeatWAVE system is a proven heating technology that has been used successfully for decades in a large number of different projects around the world. Applications include roads, cycle paths, bridges, tunnels, runways, logistics centers, driveways and parking lots, train, tram and metro platforms, level crossings, bus stops, ramps, stairs, pedestrian crossings, routes for the visually impaired, roofs and gutters (including de-icing of photovoltaic panels), agriculture (greenhouses, cultivation of crops in open fields), breeding farms (piglets, young calves) and all kinds of sports fields (e.g. football, hockey, tennis, beach volleyball).
The Amorphous HeatWAVE system is based on a uniquely designed fully grounded heat-tracing cable made of amorphous metallic tape enclosed in a mechanically robust flexible enclosure. The element is designed to meet IEEE 515.1 standards for underground and outdoor exposed applications and are fully certified and listed by INTERTEK and proudly carry the ETL mark.

How Does It Work?
With traditional means of deicing an asphalt surface with electric or hydronic means, the warming-up process is solely based on conduction. Therefore the time that is needed for the generated heat to be transported through the asphalt mixture is mainly defined by the thermal conductivity of the asphalt mixture. Using the amorphous metal tape technology, the heating process is based on a combination of conduction and long wave radiation (3 – 1000 μm) within the light spectrum. The efficiency of transforming electric energy into infra-red radiation is about 100 % and there is no electric field generated. The infra-red radiation is generated by a steel tape with a width of 25 mm and only 25μm thick which is connected to an electric circuit of 240V. Moreover, it is also possible to use another AC voltage or even a DC power source. The tape is insulated with a coating of tie-layer adhesive resin and jacketed with a PO compound and overall covered with a high density polyethylene coating (see image below).
Unique about the heat source is, that the tape is made of an amorphous metal alloy, a metallic material with a disordered atomic-scale structure. In contrast to most metals, which are crystalline and therefore have a highly ordered arrangement of atoms, amorphous alloys are non-crystalline.
Materials in which such a disordered structure is produced directly from the liquid state during cooling are called ‘glasses’ and so amorphous metals are commonly referred to as metallic glasses. The alloy contains atoms of significantly different size, leading to low free volume (and therefore up to orders of magnitude higher viscosity than other metals and alloys in molten state). The viscosity prevents the atoms moving enough to form an ordered lattice. The absence of grain boundaries, the weak spots of crystalline materials, leads to a better resistance to wear and corrosion. Amorphous metals, while technically glasses, are also much tougher and less brittle than oxide glasses and ceramics.
BETTER HEAT TRANSFER
The fact, that the metal tape is very thin also means that the generated heat easily can send forth to the surrounding area, while in case of a traditional round wire the heat is partly ‘stuck’ within the heating element itself and leading to a high temperature gradient. In case of the Amorphous heating ribbon there is a better heat flux, so no accumulation of heat and therefore no temperature stresses. In fact, the amorphous heating ribbon is 40 times more efficient compared to heating wires based on lab studies.

HEAT TRANSFER EFFICIENCY TEST
* TEST BASED ON 1 METER SAMPLES *
The large heat transfer area of the amorphous heat tape allows achieving the same heating power at a lower temperature of the heating element, thus providing improved safety.
The heat efficiency of the tape is significantly superior over the wire.
The same heat transfer power can be achieved at lower temperature in the tape's case.
Due to lower operating temperature the tape's heating element can be packed in a flexible polymer insulation which is impossible with the wire element.
HEAT UP TIME TEST
THE AMORPHOUS HEAT TAPE WILL REACH THE COMFORTABLE 30°C (86°F) TEMPERATURE IN AFTER MERELY 3 MINUTES, WHEREAS THE WIRE WILL TAKE MORE THAN 10 MINUTES. THIS MEANS OUR PATENTED AMORPHOUS HEAT TAPE STARTS TO DELIVER THE DESIRED HEAT
