Systems for condensing boiler technology An optimum gas-air mixing ratio is crucial to the energy yield realized modulation level are determined among others by the minimum and during combustion. The mixing ratio needs to be exactly adjusted maximum output of the premixing blower. This means its components to the heating value of the gases being used (e.g. natural gas, LPG need to be perfectly matched. That’s why we offer complete heating or biogas). An additional challenge is the flexibility of heat output. systems including gas blowers, venturis, gas valves and burner con- The greater the...

Gas blower State-of-the-art blower technology for modulating operation with low noise and a long service life. Venturi The pressure generated by the venturi effect provides an optimum mixture of gas and air in the pneumatic gas-air ratio control. -Q Gas valve The device required for the secure supply and the correct quantity of gas has a particularly compact design. Burner control with display The electronic control is matched precisely to the system. Signals from the burner controls can be read out and evaluated in the lab using LabVision software.

Our system solutions at a glance. All heating technology components must be perfectly harmonized in order to achieve optimum performance and efficiency. This is why we offer complete heating systems, including gas blower, venturi and gas valve, from a single source. A key benefit of our gas-air composite systems is their optimal mixing ratio with simultaneously high modulation ranges. To achieve this high level of efficiency, we provide different venturi elements for multi-venturis, depending on the heat output range. Our multi-venturi solutions provide you with a wide variety of motor...
