Description
Function
The cooling aggregate is designed for
cooling of water and other liquids like
water. The air-cooled aggregate is suitable
for tropical climate and can be operated
at up to an ambient temperature of 40° C.
A circulation pump for the cooling water,
a water reservoir and safety devices for
maximum temperature and minimum
circulation flow rate are completely wired,
installed in the aggregate and connected.
The aggregate is mounted in a square
tube frame and is mobile on 4 castors.

The hot cooling water returns into the
storage tank via the water flow switch.
The reservoir is vented to atmospheric
pressure. The circulation pump drains
the water from the container and feeds
the same to the forward line connector, at
first through the heat exchanger and after
cooling down via the thermometer probe.

The cooling agent liquefied in the con-
denser gets to the expansion valve after
passing through the water reservoir, the
dryer and the viewing glass. Here the
pressure is released from the condenser
to the evaporator pressure. In the heat
exchanger the heat required for this
expansion is taken from the hot cooling
water. The expansion valve controls the
flow of cooling agent required to cool to
a certain temperature sensed at the heat
exchanger’s output side.

Electrical control
The standard version of the cooling ag-
gregate is sized for connection to a
230 V, 50/60 Hz power supply and is con-
nected to the power via a 3-wire power
cable. The brown lead is to be connected
to the phase (R) , the blue conductor to
the neutral (Mp) and the green/yellow to
ground.

Air supply
The heat absorbed by the heat exchanger
and also the dissipation heat from the
drive of the compressor has to be dis-
charged by the air cooled condenser. If
the unit is operated in a small, self-con-
tained room the room temperature will
built up rapidly. As shown in the overleaf
diagram the cooling capacity decreases
with increasing ambient temperature. It
is therefore important that sufficient air
circulation is provided for the WLK 31.

Maintenance
All components of the cooling aggregate
are selected to be maintenance-free.
However, it is crucial that the condenser
be kept clean. Also, the cooling water
level in the water reservoir should be
observed and topped up if required.

the ambient air. Therefore, sufficient fresh
