Mixing Box Model MBE / MBP Description The mixing box type MBE/MBP consists of a housing with two round connection pipes and an integrated silencer unit for reducing flow generated noise. Two volumetric flow controllers are integrated, in order to allow the volumetric flow in ducts to be kept constant or variable or to be regulated using positive control Vmin, Vmax or "CLOSED". It is used in two-duct air-conditioning systems, in which control and mixing can be carried out electrically or pneumatically, as desired. The measuring sensor used in the cold-air connection pipe and in the silencer...

Mixing Box Model MBE / MBP Regulation Mixing boxes are used in twin-duct air-conditioning systems. 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 (low-pressure side) is less than 10%. Two control circuits independent of one another are formed, which allow the supply air to be controlled at a constant or variable flow rate. The differential pressure sensor for the cold air, with a measuring cross in the connection pipe (1), together with the cold air controller (2), forms a control circuit which is...

Installation Installation information To avoid unnecessary controller errors, the min. distances according to the following table / drawings must be observed. For combinations of several connection pieces or pieces with fire dampers or silencers, the larger minimum distances must be observed. Distance to other connection pieces (e.g. branching piece, reduction piece, T-junction, etc.) Construction Housing - Galvanised sheet steel - abrasion-resistant up to a duct velocity of 20 m/s - Lined with mineral wool, perforated sheet cover. Damper leaf seal - made of PUR, silicone-free - for...

ICHAK#Mixing Box Model MBE / MBP Technical data Volumetric flow range for MBE (constant or min/max) Attention, the following specifications are important for programming the volumetric flow controllers: - This table merely specifies the complete measuring range of the controller (volumetric flow range) - If the customer wants a calibration curve different from 12 m/ s, it must be specified! - When the air volume drops below the Vmin shown in the tables, the correct functioning of the volumetric flow controller is no longer guaranteed! - If only one air volume is specified in the order (as...

Mixing Box Model MBE / MBP Technical data of the control components Measured value collection and control function The measured value collection is carried out via a flow-favouring double measuring cross. The measuring openings are distributed over the measuring cross according to the median line method. The pressure differential formed on the measuring cross is determined by means of a dynamic or static measuring sensor. The measured values are averaged to give an average value which represents a measuring quantity for the volumetric flow. The controller compares the actual value signal...
