Construction size 5 to 7
The compressor cabinet is cooled by air intake grilles in the base and air outlet
grilles to the condenser fan intake area on both sides. The temperature in the
compressor cabinet is measured by a sensor in the ceiling area.

Evaporator
In the C7000 controller an anti freeze control can be adjusted
which activates the pump in case of a low water temperature.
Compressor
In units of size 3 and 4 there are two scroll compressors per refrigerant circuit, which can be separately
switched on and off.
In units of size 5 - 7 there are four or six scroll compressors, i. e. two or three per refrigerant circuit, which can
be separately switched on and off.
In combination with the possibility, to individually operate the refrigerant circuits the total capacity can be
graded in steps of 25 resp. 16,7%.
The compressor contains a crankcase heater.
Electric cabinet
The electric cabinet is divided into a load section and a control section
with separate door. The load section contains a power switch, operable
from outside which locks the cabinet door when switched on.
A thermostatically controlled air/water heat exchanger for cooling at
high ambient temperatures is situated inside the electric cabinet on the
left side.

Condenser
Construction size 3 and 4
The necessary air for cooling is drawn in across the condenser coils placed on the right side and blown ver-
tically upward through speed-controlled axial fans (EC technology). The condenser coil consists of a micro-
channel coil completely made of aluminium.
Construction size 5 to 7
The necessary air for cooling is drawn in across the condenser coils placed on the long side and blown verti-
cally upward through speed-controlled axial fans (EC technology). The W-shaped arrangement of the micro-
channel coils completely made of aluminium increases the heat exchange surface which gets in contact with
intake air and improves the energy efficiency.
