Every Trevil generator works with tubular electric heating elements immersed in water.

Our heating elements are composed of a resistive wire coil immersed in compressed magnesium oxide, protected by a metal sheath of Incoloy alloy, corrosion-resistant and with good “self-cleaning” capacity thanks to the thermal expansion which expands the coils, breaking the coating of scale that tends to deposit around the hot points.

Small generators are fitted with a single heating element, but above a total generator power of 8 kW the heating elements are fractionated, so that it is possible to switch on separately only the ones necessary for the consumption required at the moment.
