MHTC Flow - System Overview
Figure 5: System Overview – MHTC Flow
Functional Description
The MHTC flow model provides multistep control by means of the MHTC total control unit and
the step valves (1, 2 or 3 step valves depending on the humidifier capacity). The MHTC total
control unit (for wall mounting) processes analog sensor/control signals and uses them to
control the step valves. This allows multistep control (1 to 3 steps depending on the humidifier
capacity) which improves control accuracy compared to the MHB Flow model.
In case of a humidification/cooling request one, two or all three step valves open (depending
on the request). The water flows via 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.
If the MHTC Reflow model is equipped with the optional uv water treatment, all the water is led
through the uv water treatment unit where it is sterilized before it is introduced to the
humidifier boxes.
