The latest systems with condensing technology are the key to increasing the efficiency of heaters.
System Ventilation 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.

System Ventilation 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.
