18 Product Overview
Functional description
The water tank is lled up to a preset upper level via the level-controlled inlet solenoid valve (NC). When
the water level in the water tank drops below a certain limit, the level-controlled inlet solenoid valve opens
until the upper limit is reached again.
The Condair ME Control provides On/Off or stage control by means of the Condair ME Control control
unit and the stage pumps. The Condair ME Control control unit processes analog sensor/control signals
and uses them to control the stage pumps.
In case of a cooling request with activated On/Off control the inlet solenoid valve (NC) opens and
all stage pumps start and the water ows to the distribution headers above the evaporative cassettes.
In case of a cooling request with activated stage control the inlet solenoid valve (NC) opens, then de-
pending on the demand signal and evaporative module size up to ve stage pumps start and the water
ows to the distribution headers above the evaporative cassettes.
The distribution pipes inside the distribution headers evenly supply the water to the entire surface of the
evaporative cassettes where it ows down and cools the air owing through the evaporative cassettes.
The excess water not used for cooling ows to the water tank.
To prevent accumulation of mineral residues and the formation of germs in the water tank, the tank is
completely drained periodically (interval or time controlled). Additionally further hygiene functions can
be activated: Operation-dependent draining of the water tank (ll cycle, conductivity, temperature or
time controlled).
