European Legislation

The European Union has set a clear course with stricter environmental legislation: refrigerants with a high global warming potential (GWP) are being phased out gradually. The recent revision of the F-gas Regulation (EU 2024/573) imposes increasingly stringent requirements on the use of traditional refrigerants. This is forcing the refrigeration industry – and therefore also the agricultural sector – to make sustainable choices.

At Mueller®, we are leading the way in this regard. Our E-Star R-290 refrigeration machine has been specially developed in response to these changes. The system combines top quality with sustainability and energy efficiency, so you are ready for the future.

What is R-290?

R-290 is a natural refrigerant with an exceptionally low GWP of only 3. By comparison, many traditional refrigerants have a GWP of over 1,000. This makes R-290 one of the most environmentally friendly choices available and fully in line with the EU's climate neutrality targets.

Why choose the E-Star R-290?

Our E-Star R-290 cooling machine is designed with the highest performance and the strictest standards in mind:

• Low investment compared to alternatives such as CO₂ (R-744) and ammonia (NH₃).
• Up to 30% higher energy efficiency, thanks to the subcooling system and advanced valve management.
• Fully compatible with all current and future Mueller milk coolers.
• Automatic, software-controlled valves for optimal control.
• Smaller ecological footprint, thanks to low energy consumption and natural refrigerant.
• Weatherproof housing, designed for long-term outdoor use.
• Safely designed in accordance with EN 378-2, the European standard for systems with flammable refrigerants.

Efficient, Sustainable, & User-Friendly

Thanks to its simple installation and robust design, the E-Star R-290 can be easily integrated into your existing systems. You benefit from lower energy consumption, reduced operating costs, and maximum reliability, while complying with current and future regulations.
