MHB Flow - System Overview
Figure 3: System Overview – MHB Flow
Functional Description
The MHB Flow model provides on/off control by means of the MHB control unit and an
external on/off humidistat. In case of a humidification/cooling request the supply valve opens
and the water flows via the pressure reducing valve (accessory), the water filter (accessory)
and the manually adjustable volume controlling valves to the distribution pipes above the
humidification boxes.
The distribution pipes evenly supply the water to the entire surface of the humidification boxes
where it flows down and humidifies the air flowing through the humidification boxes. The
excess water not used for humidification flows to the water tub and then directly to the drain.
