BITZER Showcases Natural Refrigerant Compressors for Mobile HVAC at Busworld 2025

BITZER's focus on propane and CO₂ compressors signals a strategic pivot towards sustainable refrigerants within the rapidly electrifying public transport sector. At Busworld Europe 2025, BITZER will present its latest compressor technologies designed for bus air conditioning and heat pump systems, emphasising both energy efficiency and the use of natural refrigerants. The exhibition, taking place in Brussels from October 4-9, will serve as a platform for BITZER to showcase its commitment to environmentally conscious solutions for mobile applications, located at Stand 528 in Hall 5. A key highlight of BITZER's presentation will be the expansion of its EL.7 scroll compressor series to include variants utilising propane (R290). This move builds upon the company's established expertise with propane in other applications and underscores propane's growing acceptance as a viable, future-proof refrigerant. BITZER cites propane's low global warming potential (GWP) and its suitability for mobile air conditioning and heat pump systems as key drivers for this development. Propane's thermodynamic properties facilitate efficient operation even at lower ambient temperatures, a critical factor for maintaining passenger comfort in diverse climates. Alongside the propane-based EL.7 scroll compressors, BITZER will feature the CO₂LITE reciprocating compressor. Optimised for transport applications, this compressor is designed to operate with CO₂ (R744), another natural refrigerant with a negligible GWP. Oliver Rathfelder, Director of Sales Transport at BITZER, noted that "An efficient and reliable air conditioning and heat pump system is key when it comes to increasing the range of electric buses and ensuring a high level of passenger comfort." BITZER's focus on natural refrigerant compressors for mobile HVAC applications positions the company to capitalise on the growing demand for sustainable climate control solutions in the transport sector.
