STULZ enhances the sustainability of its CyberAir 3PRO DX series with low-GWP R513A refrigerant
March 2023 by Marc Jacob
STULZ has announced that selected units from its industry leading CyberAir 3PRO DX range are now available with R513A low Global Warming Potential (GWP) refrigerant. This pioneering development highlights the company’s ongoing commitment to providing the most sustainable air conditioning systems for data centres, and it is already working on further product conversions that will extend the use of R513A refrigerant throughout its portfolio.
As a drop-in refrigerant, R513A achieves similar energy efficiency and performance to R134a. In addition, R513A refrigerant belongs to the A1 safety classification, which means that it is neither toxic nor flammable, according to the American Society of Heating, Refrigerating and Air Conditioning Engineers’ (ASHRAE) guidelines. R513A refrigerant therefore ensures uncomplicated handling, making it ideally suited for data centre applications.
In light of increasing pressure on data centre owners, operators and users to reduce their environmental impact, STULZ decided to start its R513A refrigerant rollout with its innovative CyberAir 3PRO DX computer room air conditioner (CRAC) solution. In doing so the company has become one of the first manufacturers of data centre CRAC units to incorporate the use of R513A refrigerant in its technology.
CyberAir 3PRO DX achieves maximum cooling capacity with a minimal footprint, and is more adaptable than any other precision CRAC unit on the market, thanks to an optimised equipment efficiency ratio (EER) and the potential for savings through indirect dynamic or direct free cooling. With immediate effect, selected units with on/off compressors from the ASD/ASU and ALD/ALU model series of the CyberAir 3PRO DX range are available with R513A refrigerant.
