Air-cooled chillers and heat pumps for outdoor installation

Versatile, super-quiet and energy-efficient

Thanks to their state-of-the-art technologies, the chillers and heat pumps feature efficient performance and low noise emission. Various different models are available for nearly all unit series.

- Standard
- Super quiet
- Highly efficient

Various different technologies are provided, depending on the capacity stage.

Compressor:
Whether scroll compressor in inverter or standard version, or screw compressor in the larger capacity range, the entire band width is covered.

 

Heat exchanger:
Both are offered, no matter whether plate or shell-and-tube heat exchanger for heat exchange with water as medium.
Air-cooled heat exchangers are offered as copper/aluminum (Cu/Al) or micro-channel heat exchanger versions. Depending on the ambient conditions, you can select between different heat exchanger coatings to protect against corrosion and other environmental influences.
