Float switch
The float switch monitors the water level in the tank.
A signal lamp in the control cabinet door indicates lack of water when the water level falls
below the minimum level. The cooling operation remains activated.
If the water level continues to fall and once the minimum limit value is reached, cooling
operation and pump(s) will be switched off.
Restarting the process cooler is not possible until the water has been replenished up to the
MAX mark at the filling level indicator.
The float switch is located in the tank.
Fan control
The condensation pressure is controlled by cycling the individual fans on and off.
This type of control permits an adaptation to different operating conditions at relatively constant
condensation temperatures.
Control and Operating Unit
The control and operating unit controls the water circuits and the refrigeration circuit.
The control panel with display of the water temperatures, as well as the error codes in the case
of a general fault alarm, is integrated in the control cabinet door.
2.6 Electrical / Control Equipment
The electro-technical equipment of the process cooler is installed in the control cabinet. All
required components for the automatic switching, controlling and regulating operation are
contained in the control cabinet.
The main electric circuits are of a non-fused design featuring motor protecting switches.
The connection of the process cooler to the equipment to be cooled is effected via a potential-
free interface.
The interface transmits the following signals:
- „ Malfunction ’’ Continuous signal from the process cooler to the equipment to be cooled.
The water outlet temperature is kept constant by the control and operating unit at a given
setpoint value by activation of power stages in the refrigeration cycle. The current water outlet
temperature is displayed on the control panel.

3. TRANSPORT AND STORAGE
The safety notices contained in Chapter 1 must be complied with !
As a rule, the process cooler must be transported in upright position without water
charge !
The in-house transport is carried out by a forklift, lift truck or crane.
This process cooler must be placed on a level surface in order to prevent any distortion of the
base-frame.
3.1 Transport Specification
- Weight
- Main dimensions
- Ambient temperatures –20°C to +60°C
In ambient temperatures <0°C the water circuits must be completely drained, including pumps,
water filters and tanks.
(See Chapter Decommissioning)
3.2 Transport Using a Forklift
To transport the process cooler with a forklift, the recesses provided at the broadside of the
base-frame of the unit should exclusively be used. Do not lift the unit until the forks have been
inserted horizontally all the way beneath the unit, symmetrically to the centre of gravity of the
process cooler.
The lifting rate should be kept to a minimum!

3.3 Transport Using a Lift Truck
Handling the unit from the narrow side:
The process cooler can be transported by means of two lift trucks with the forks being inserted
under the load from the narrow sides.
To ensure that the forks can be inserted under both cross beams, a minimum fork length must
be maintained.
Both lift trucks must be actuated at the same time in order to prevent the process cooler from
becoming off-centred.
The lifting rate should be kept to a minimum!
Handling the unit from the broadside:
The forks of the lift truck must extend all the way through the unit, the fork rollers must project
from the other side of the unit.
Only then may the process cooler be lifted; exercise care to prevent the load from becoming
off-centred.
The lifting rate should be kept to a minimum !
The process cooler can be transported by means of a single lift truck with the forks being
inserted under the load beneath the recesses, from the broadside, symmetrically to the centre
of gravity of the process cooler.
