The burner motor drives both, the fuel pump and the ventilator.
The burner motor switches on as soon as the burner is activated on the display.

The two- stage fuel pump is driven by the burner motor. On this fuel pump are
two shut- off valves with magnetic valves assembled which makes that the fuel
either gets to the burner or gets back to the fuel tank. The two- stage fuel pump
is a pump that works on 2 different pressure stages. Therefore, the burner
does not have to work at full power but can also operate at a lower pressure.
In case of demand, the first pressure stage is addressed and the burner will
work on a lower power capacity to automatically switch over to full power
capacity (second stage) afterwards. The pressure stages are software adjusted
which automatically set the burner pressure (depending flow). By using a
two- stage fuel pump, the burner switches less (less service sensitive) and fuel
consumption is optimised.

The ventilator makes sure that there is sufficient air for the combustion and
also for the cooling of the burner wall. The ventilator is driven electrically and is
mounted at the bottom of the burner.

The ignition transformer is mounted indirectly against the burner chamber.
The transformer ensures a (continuous) ignition spark in the burner chamber.

As soon as there is sprayed, there is a flow through the flow switch. The switch
controls if there is a flow of water. At sufficient flow the burner can function.

If the pressure in the water circuit gets to high by unexpected circumstances,
the pressure relief valve opens and the water runs outside through a hose.

The frame is mounted on an iron construction lacquer with vibration isolators.

The run- dry alert is mounted inside the water tank. If the level in the water tank
is to low, the motor gets switched off by means of a dry run alert (via run dry
protection or a level indication visualised on the display via a transmitter). If the
level in the fuel tank is to low, the motor gets switched off by means of a dry run
alert. The cleaner goes in failure.

The fuel tank you can find at the back of the trailer and is equipped with filling
cap and run- dry alert (via run dry protection or a level indication visualised on
the display via a transmitter - according to the selected option).

The heat exchanger is situated below the water filter and is used to cool the
engine, through the heat exchanger cold water will be flowed in the primary
circuit, in the secondary circuit the hot water flows coming from the engine.
The heat exchanger ensures now that the secondary circuit will be cooled and
there hotter water flows through the primary circuit into the high pressure pump.
