Chiller uses climate friendly refrigerant with range of 300 to 1000 kW

Stulz is extending its product portfolio to include new ze chillers in the CyberCool 2 series. These employ proven CyberCool 2 technology and have been optimised specifically for use with climate-friendly HFO-1234ze refrigerant.


The new chillers are available in air-cooled versions and are designed for use with eco-friendly R-1234ze refrigerant. This single HFO has a very low global warming potential (GWP) and, in the context of (EU) regulation no. 517/2014 and together with refrigerant shortages, is a future-proof and efficient alternative to conventional HFC-based refrigerants. The chillers are available in various output capacities from 300 to 1000 kW and offer reliable and efficient cooling solutions for medium and large data centres, telecommunications and industrial applications.


Like the CyberCool 2 chillers that were introduced in 2013, the ze series is also equipped with the largest possible EC fans and sound-insulated compressor chambers to reduce noise emissions. Thanks to specially developed technology, the CyberCool 2 also supports indirect free cooling. This intelligent way of changing over between compressor operation and indirect free cooling facilitates resource-saving operation coupled with maximum energy efficiency.


Mix Mode Boost technology can also use the entire surface of DX coils without needing to regulate the fan speed, which further increases energy efficiency and significantly reduces operating costs. Microchannel condensers constructed entirely of aluminium and equipped with air baffles also optimise flow into the inner coil elements.
