In the shift toward renewable energy and decentralised power systems, climate compliance doesn’t stop at energy generation; it extends to every component in your infrastructure, including cooling.

From 1 January 2027, the European Union will require all new climate control units to use refrigerants with a GWP (Global Warming Potential) below 150. This marks a significant change in how systems are specified for control rooms, battery energy storage systems (BESS), switchboards, and power skids, especially for suppliers to regulated markets or large infrastructure projects.

To support this transition, Rittal is upgrading its Blue e+ portfolio with F-gas-compliant refrigerants that meet upcoming standards without compromising thermal stability, reliability, or service life.

What’s Changing in the Blue e+ Product Line?

Starting in 2026, Rittal’s cooling units and chillers will begin shipping with R-1234yf, a next-generation refrigerant with a GWP of just 0.5. Already proven in industrial and automotive systems, R-1234yf offers excellent environmental performance, low toxicity, and system compatibility.

Product availability in Australia:

• Cooling units (0.3–5.5 kW): From Q1 2026
• Chillers (1.5–7.0 kW): From Q2 2026

New item numbers will apply. Performance features will remain consistent:

• ±0.5 K temperature accuracy for control electronics
• Inverter-driven energy efficiency
• Reduced refrigerant volume with microchannel design
• Multi-voltage support and global approvals

As energy infrastructure becomes more distributed, exposed, and digitally integrated, cooling systems are now expected to contribute to broader operational objectives,  including emissions reduction, lifecycle risk management, and alignment with international compliance requirements.

Whether integrated into BESS enclosures, containerised substations, or utility switchrooms, Rittal’s Blue e+ cooling solutions are now designed to meet both the performance and environmental demands of modern energy infrastructure.

And with R-513A-based systems remaining available where permitted, Australian projects can choose the most appropriate option while preparing for future compliance.
