Mechanical Mixing Box Model MBM Description Mixing boxes are used in twin-duct air-conditioning systems. The Mixing Box Model MBM consists of a casing with two circular connections and an integrated sound absorber for reducing noise generated by flow. The round connection spigots contain elliptical control flaps, which are responsible for regulating the air temperature. The unit mixes cold and hot air in such a way that the difference between the highest and the lowest temperature at the outlet of the device is less than 10%. The actuator for the cold and hot air dampers, which are mounted offset...

Mechanical Mixing Box Model MBM Setting curves for air volume regulation Controller setting MBM 315 Controller setting MBM 125 Controller setting MBM 400 Controller setting MBM 160 RS = controller setting Controller setting MBM 200 For correct design and use of the dual duct terminal box MBM, we recommend not exceeding the max. controller setting of 10. This ensures that the mechanical constant volumetric flow controller is working in the optimum range. Attention! The MBM 315 is equipped with 2 VM-PRO-250, both constant controllers being activated in parallel, i.e., the air volume must be calculated...
