Model advantages

The innovative ASR series is designed for accurate, quiet and cost-effective trouble-free cooling.

  • Frees up space due to the fan section, which is installed under the floor.
  • The special design creates optimal airflow distribution and reduces operating costs in accordance with ASHRAE guidelines.
  • Combines compressor and free cooling, reducing energy consumption.
  • It has a unique dynamic control system that takes into account the outdoor temperature and the current heat load in the data center. The system automatically selects the most economical operating mode.
  • The EC compressor provides highly accurate control and quick response to changing heat loads.
  • Operated by a controller and a switch on the front panel. It is possible to connect to a unified control system up to 19 separately located units with a line length of up to 1000 m.
