MAIN FEATURES

Two pressure vessels

Total boiler capacity is split into two vessels, for more modularity and easier maintenance.

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.

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.

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.

OPTIONS

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.

Economizer

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.

Geyser-TRON automatic power management

The exclusive Geyser-TRON system automatically modulates the active power of the boiler according to the actual steam consumption of the system, thus avoiding waste.
In a Geyser boiler, the total installed power is provided by several heating elements. The Geyser-TRON electronic system is able to recognise how much steam the system actually needs, and switches on just the number of heating elements needed to provide that steam output. If steam consumption increases, it switches on one or more additional heating elements; if consumption decreases, it switches them off.
Geyser-TRON is available as an option on Geyser generators 24 kW and over.

160A main switchES

The switches are installed on the door of each electric box and prevent opening the door when the switch is in the ON position.
The electric box can be accessed only when the switch is in the OFF position, that is when there is no live current.

Ventilation electrical system

The system prevents overheating of the electrical panel when the generator is installed in a warm environment.

Automatic drain valve

The system allows to drain the boiler automatically.
The presence of compressed air is required.
