STULZ has added chillers with a stepless capacity control (EC compressor) and an output from 20 to 100 kW to its portfolio. Chillers from the CyberCool Indoor series have been designed for indoor installation. The new version was specially engineered to precisely adapt to low or fluctuating heat loads. With a maximized temperature range from 4ºC to 18°C at the chilled water outlet, the CyberCool Indoor is suitable for a broad range of applications including data centers, medical technology, and process industries.

Chillers from STULZ's CyberCool Indoor series are available with a choice of three systems: air-cooled with external condenser, water-cooled, or the TCO-Leader with Indirect Free Cooling and intelligent mode switching (compressor cooling, free cooling, or mixed mode). All three systems can be standardly equipped with ON/OFF compressors or with new energy-saving EC compressors. These EC versions contain two complete, redundant refrigerant circuits and ensure high efficiency in partial load, according to the company.
