STULZ to use low GWP R454C refrigerant in data centre

 STULZ has announced a new CyberAir 3PRO DX GE4(S) range for use in data centres. The latest addition to the highly successful GE series of precision air conditioning systems with indirect free cooling, the CyberAir 3PRO DX GE4(S) range is available in three sizes with capacities from 24kW to 71kW to suit a variety of room volumes and power requirements.

As part of its commitment to delivering innovative solutions with minimal environmental impact, STULZ has configured the CyberAir 3PRO DX GE4(S) range to use future-proof A2L R454C refrigerant. A2L refrigerants, named after their ASHRAE safety classification, are non-toxic, flame-retardant, deliver high levels of energy efficiency, and have reduced global warming potential (GWP) ratings. R454C has a GWP of only 148 and meets the requirements of the F-Gas Regulation 2024/573. Safety in mission-critical environments is vital, and a central element of the CyberAir 3PRO DX GE4(S) range is an internal safety concept, which has been specially developed for use with low-GWP refrigerants

Senior product manager for room cooling at STULZ, Sebastian Maron, says, “R454C offers extensive advantages over other commonly used refrigerants. The F-Gas Regulation 2024/573 is a European Union law aimed at significantly reducing emissions of fluorinated greenhouse gases. It tightens the phase-down schedule for hydrofluorocarbons (HFCs) and promotes the use of climate-friendly alternatives like R454C. We are delighted to be able to offer customers maximum investment security and support the reduction of the CO₂ footprint in data centre cooling through innovative design and sustainable development.”

The refrigeration circuit is certified and tested to be permanently leakproof, while its optimized design also prevents refrigerant build-up within the unit. Additionally, two explosion-proof gas sensors are located in the housing and the control cabinet to continuously monitor refrigerant concentration. If elevated levels are detected, the system automatically shuts down all electrical components, except the fans, and triggers an alarm.

STULZ recognizes the importance of user friendliness, and its advanced E² control system with touchscreen display enables intuitive operation of the CyberAir 3PRO DX GE4(S) range.
