ROOF-MOUNTED OOF-MOUNTED COOLING COOLING UNITS
UNITS
The cleverly thought-out design of our cooling units makes them service-friendly and easy to handle, thanks to a
number of detailed solutions.
The louvred grilles are removable, providing access to all cooling unit components in the external circuit. The
control and power electronics in the new microcontroller are housed separately in a separate electronic box,
protecting them from dust and moisture. If necessary, the entire electronics easily and quickly replaced.
For every type of enclosure installation, there are cooling units with various designs of internal and external air
circuit.
For example, roof-mounted cooling units with front air intake and also suitable for baying several cooling units
adjacent to one another.
Economical power consumption, thanks to exceptionally high refrigeration factors

Recooling systems for central heat dissipation
Designed as large-scale cooling units, they are used in enclosure, machine and process cooling. Such largescale
applications demand a high cooling output.
Using the very latest technology, we have compiled a customer-oriented range of cooling components based on
the modular system.

Cooling output 4-50 kW. The cooling system is integrated into a PS 4000 perfect panel system. This allows it to be
“seamlessly” bayed to the enclosure. The modular configuration allows customer-specifc requirements to be
implemented.

Cooling output 1 – 20 kW. The cooling system is mounted on a base plate. A highly flexible and modular concept,
based on the machine enclosure or design.
