Direct evaporation systems
Cost-saving direct evaporation systems – efficient air cooling
In all applications in which large fresh or recirculating air flows are cooled, we offer you the advantages of direct evaporation technology.
This involves direct cooling of the air through the evaporating refrigerant in the cooling coil – an intermediate medium such as chilled water is not required. You benefit from significantly better energy efficiency compared to conventional cooling systems. Additionally, the investment costs for complex cold-water piping including pumps and control groups are eliminated.

Features
What our solutions have in common:
flexibility, efficiency and sustainability
Up to 40% lower
energy consumption
through direct air cooling without an intermediate medium
Turnkey
refrigeration system
including cooling coil, piping and commissioning
Highest
control accuracy
by stepless power control
Optional
heat recovery

Keyfacts
We optimize customer benefits through
comprehensive measures:
Reduction of trade interfaces
through turnkey supply of the complete cooling system –including refrigeration machine, pipework, cooling coil and control technology
Small footprint and flexible installation
due to compact design and variable layout – ideal for decentralized retrofitting on existing installations
Complete elimination of cold water technology
i.e. cold water generation, piping including insulation, buffer tanks / switches, primary and secondary pumps, cold water control groups and coils and frost protection measures are not required
Reduction of investment and maintenance costs
by setting up combined systems for connecting several cooling coils with independent power control to one system
Individual plant configuration
e.g. for indoor or outdoor installation, in compact or split design, air- or water-cooled, modular design, redundant / multi-circuit design, sound insulation
Consideration of customer specifications
such as mechanical / electrical factory specifications, manufacturer specifications, special control cabinet equipment, communication interfaces, safety devices, etc.
