H₂-ready:

RadiMix HS 122 with CleanEco Sense

The robust RadiMix HS 122 system ensures highly efficient combustion through seamless coordination of its components, whether operating on natural gas, biogas, or 100% hydrogen.

Its advanced CleanEco Sense combustion control system integrates the VG 122 gas blower with the BCU 110 burner control unit and the smart G32G02 gas valve for optimal performance.

Natural gas, biogas or 100% hydrogen

The new electro-pneumatic CleanEco Sense system can be configured for a very lean start of the condensing boiler. This makes it suitable for both conventional and hydrogen operation.

Plug and play solution

Short integration time compared to other electronic gas-air control systems.

Cost effective conversion

Conversion to hydrogen always requires the replacement of the burner. However, our components – blower, venturi, gas valve and burner control – can remain unchanged.

Motors for boarding aids

The CleanEco Sense G20G02 gas valve, in conjunction with the BCU 110 burner control unit, ensures that the boiler starts safely. In addition, flashback can be prevented when igniting with hydrogen.

Turn-down ratio 1:15

The best in class turn-down ratio 1:15 allows the output of the boiler to be precisely matched to the actual heat demand of the home.
