The BING gas mixer type 22 is a design for the supply mixture of block heat and power plants with gas operation. There are needle valves for use with propane and town gas available, other versions are possible.

The housing of the system consists of die-cast aluminum and has a KTL coating. The throttle body includes a linear stepper motor with a nozzle needle for metering and shut-off of the combustible gas and a rotary stepper motor which moves the throttle valve. The gas port has a taper thread, making it gas-tight. The nozzle is tested and approved by the “Verein der Deutschen Gaswirtschaft” (“Association of the German Gas Industry”).
