Recooling systems
Assembly
Unity with enclosures
For example, recooling systems may be connected directly
to a bayed enclosure suite, providing effective, centralised
cooling for all enclosures and housings on a machine or system.
Recooling systems in the TS 8 Top enclosure system are easily
integrated into existing enclosure combinations. For applications
in confined conditions, the Mini-recooling systems for
wall and roof mounting are ideal, with their space-saving,
compact design.

Spatially separated
High heat loads can even be dissipated in confined and awkward
spaces, thanks to the spatial separation of the recooling
system from the enclosures and machine. In all cases, as
well as enclosure cooling, cooling water may also be produced
for process and machine cooling or for cooling liquid
media.
Recooling systems in floor-standing and industrial enclosures,
with their robust design, are the ideal stand-alone
solution, and provide optimum service accessibility.

Outdoor siting
To avoid putting additional pressure on the factory air with
the waste heat incurred during the process, the recooling
system may be supplied with the option of outdoor siting (for
ambient temperatures up to –20°C).
In such cases, a rain canopy should be provided to protect
the recooling system from extreme weather. The water circuit
must be filled with 34 % anti-freeze agent Antifrogen N (or
equivalent) to 66 % water in relation to the total water volume.
