Modular heating elements

The total power of the generator is split into smaller heating elements that may be individually controlled. The number of heating elements in function can be selected according to steam consumption. The (optional) Geyser-TRON system performs this action automatically.

Incoloy elements

We use premium Incoloy elements which feature superior resistance to heat and stress corrosion. Incoloy elements also reduce the need for boiler cleaning, as they naturally remain cleaner from limescale compared to other materials.

Electronic level control

The water level in the boiler is electronically controlled and refilled by an electric pump. Valves prevent water backflow into the supply line and boiler flooding during hours of inactivity.
The level control circuit has been designed so as to prevent phenomena of galvanic corrosion.
The level control circuit has built-in protections against generator malfunction, for example dry running and excess pressure.
There is no floating ball and therefore no mechanical parts that may fail.


Condensate recovery tank

Each Trevil generator can be equipped with a stainless steel tank for condensate recovery. The temperature in the water tank is controlled by thermostat to avoid water overheating and steam plume.


The economiser allows 50% saving on water consumption and 5% on energy consumption.
The condensate recovery tank, by itself, allows saving water and energy. Higher savings can be reached implementing our economizer, that is a heat exchanger which pre-heats the water entering the boiler exploiting the residual heat of condensate entering the tank.
The economizer is particularly recommended in systems that produce much condensate.
