Heating technology systems and components for commercial and large-scale applications

Modern gas condensing technology offers optimal and future-proof solutions for supplying apartment blocks, schools, hotels or large industrial plants with heat and hot water efficiently, while saving on costs and keeping emissions low. 

System efficiency for large units

ebm‑papst even offers optimum systems and components for applications ranging from 50 to 400 kW. We also supply the right high-efficiency solutions for single boilers for commercial buildings as well as for cascaded systems for large urban complexes. Thanks to decades of experience, our heating systems, including gas blowers, Venturi, gas valves and burner control systems, always work with the optimum gas/air mixture. Regardless of the required power, and irrespective of the gas used. This enables our systems to achieve unique combustion efficiency.


ebm‑papst gas condensing technology solutions from 50 kW to 4 MW offer these advantages:

  • Highest efficiency level
  • Compact design
  • High modulation rates
  • Easy integration
  • Minimal noise emissions
  • Unique heat output capacity of up to 4 MW

Many of our products are tested by the German Technical and Scientific Association for Gas and Water (DVGW) for 20 percent hydrogen, e.g. the gas blowers G1G 170, G3G 200, G3G 250.

RadiMix HS 122 with CleanEco Sense

The powerful RadiMix HS 122 system solution guarantees efficient combustion thanks to the perfect coordination of its components - regardless of whether it is fuelled with natural gas, biogas or 100% hydrogen.

Its CleanEco Sense combustion control system combines the VG 122 gas blower with the BCU 110 burner control unit and the intelligent G32G02 gas valve.

CleanEco Sense: the new gas-air combination for clean heat.

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.

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

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

The CleanEco Sense G32G02 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.

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 house.

Korea’s Number One Gets Fired Up

Thanks to its efficient and robust components, Korean heating technology manufacturer KD Navien was able to launch a condensing boiler on the market that works reliably even under the most adverse conditions.
