Stulz Oceania has announced that selected units from its CyberAir 3PRO DX range are now available with R513A, a low global warming potential (GWP) refrigerant.
According to the company, this highlights its ongoing commitment to providing the most sustainable air conditioning systems for data centres, and it is working on further product conversions that will extend the use of R513A refrigerant throughout its portfolio.
Stulz Germany Sales Manager Mirko Hoffmann says R513A offers extensive advantages over other commonly used refrigerants such as R134a.
“It has a 56 per cent lower GWP than R134a and meets the requirements of the current European Union (EU) F-Gas Regulation, which aims to reduce the EU’s fluorinated greenhouse gas emissions by two-thirds by 2030,” says Hoffmann.
“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 ASHRAE guidelines. R513A refrigerant therefore [makes it] ideally suited for data centre applications.”
Stulz says it decided to start rolling out R513A following increasing pressure on data centre owners, operators and users to reduce their environmental impact. 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, says Hoffmann.
The company says the CyberAir 3PRO DX also 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.
“Stulz understands the need for data centres to operate as sustainably as possible, so we focus on providing products and systems that meet this requirement,” says Hoffmann. “By switching the CyberAir 3PRO DX to low-GWP R513A, we are able to offer our customers an environmentally friendlier alternative to conventional refrigerants such as R134a. This is just the tip of the iceberg … we are already working on using further low-GWP refrigerants across our range, enabling our customers to position themselves sustainably.”
