NASRC's R-TRADE initiative has opened registration for five free natural refrigerant training events running from December 2026 to June 2027. The series pairs hands-on CO2 and propane instruction with a regional strategy that differentiates between growth markets and established systems.
CEN has released the enquiry version of prEN 378:2025 for national standardisation committee review. The revision introduces a risk-based design approach that eurammon welcomes, though charge limit restrictions and prescriptive safety caps remain barriers to wider natural refrigerant adoption.
At Chillventa 2026 in Nuremberg, Epta and Hauser exhibited jointly for the first time, presenting transcritical CO2 systems, HAUSER XL Rack industrial units, R290 commercial cabinets, and the MyEpta digital platform.
A pilot project in Volgograd demonstrates how a secondary-loop architecture using propylene glycol enables the use of natural refrigerant R290 in retail without long refrigerant piping in the sales floor.
Clivet has commissioned a new 14,000 sq m heat pump factory in Feltre, Italy, with an annual capacity of up to 8,800 units. The facility is dedicated to commercial-grade heat pumps using natural refrigerants and is equipped with an 805 kWp photovoltaic system.
Daikin Europe has commissioned Europe's first CO2-based VRV system at a Denns BioMarkt supermarket in Wiesbaden, Germany, integrating it with propane-based built-in refrigeration equipment under a unified BMS control. The CO2 VRV range currently features a single 10 HP outdoor unit; scaling across the full VRV lineup and chillers is planned for 2028.
Merak has become the only rail HVAC supplier offering serial production units on both natural refrigerants — CO2 (R744) and propane (R290). According to the company, thousands of Greenair heat pumps have been installed worldwide, reducing energy consumption by at least 30% compared to resistive heating.
