The biggest thing to happen in the refrigeration industry in Nuremberg is the arrival of Chillventa 2024, the world’s leading trade fair dedicated to refrigeration, air conditioning, ventilation, and heat pump technology. The event keeps a tight focus on innovation and sustainable cooling solutions and attracts industry professionals from across the globe in the thousands. A key highlight of the 2024 edition is the increasing prominence of natural refrigerants as the industry shifts towards environmentally friendly cooling solutions. Eight companies that have received the prestigious ATMO Approved Natural Refrigerants Label for 2024 showcased their latest advancements at the event. This label, introduced by ATMOsphere in 2022, recognizes manufacturers that excel in developing natural refrigerant systems using CO2 (R744), ammonia (NH3), and propane (R290). Among the companies exhibiting at Chillventa are GTS (hydrocarbon producer and distiller), Refra (CO2 transcritical rack and propane heat pump manufacturer), SCM Frigo (refrigeration systems manufacturer), and Fenagy (industrial CO2 and hydrocarbon heat pump producer). The ATMO Approved Label aims to support manufacturers in marketing their sustainable products to new customers and regions while helping end users identify best-in-class suppliers. To qualify for the label, companies must demonstrate excellence in their vision, customer satisfaction, and measurable impact. For 2024, ATMOsphere introduced additional criteria, including stringent training requirements for partners, contractors, and staff, as well as a commitment to avoiding per- and polyfluoroalkyl substances (PFAS), such as trifluoroacetic acid (TFA). The real benefit for local players in Nuremberg’s refrigeration industry is the comprehensive program featuring expert lectures, guided tours, and networking opportunities. Attendees, including manufacturers, HVAC professionals, architects, and retailers, gained valuable insights into the latest industry trends and regulatory developments shaping the future of refrigeration technology. These are the tools that will empower German companies to remain their competitive edge on the global market.
