Sustainable refrigerants as a key factor

With its extensive range, BITZER, the specialist for refrigeration and air conditioning technology, offers a whole host of products for sustainable and energy-efficient solutions. In this regard, the topic of refrigerants plays a key role – but no single refrigerant is appropriate for all applications. Here is how to find the right one.

With its products and services for refrigeration and air conditioning technology for the railway sector, BITZER ensures optimum temperature conditions – always within the context of maximum quality and energy efficiency. The company offers the right technology for any application and almost every refrigerant – with a particular focus on legal regulations such as the Ecodesign Directive and the F-Gas Regulation – yet choosing the appropriate refrigerant can still be a challenge.

Finding the optimum refrigerant with BITZER

The topic of refrigerant has taken on great significance in the past years and will continue to be at the top of the agenda. Some refrigerants are toxic and/or flammable, others have a high global warming potential (GWP), and the CFCs and HCFCs banned in developed countries damage the ozone layer. Choosing the right refrigerant therefore has a role in determining whether systems are economic, environmentally friendly and efficient.

The BITZER Refrigerant Report provides a useful guide: the company published its first Refrigerant Report in 1992, a groundbreaking achievement. Since then, the Refrigerant Report has served as a well-founded and neutral source of information both inside and outside the sector, as it regularly takes up current requirements and trends and presents and explains them in a clear and concise manner. The current issue can always be found at

BITZER has approved its compressors commonly used in the railway sector for natural and low-GWP refrigerants: compressors of the ECOLINE series can be used with propane, CO2, R513a and all other common low-GWP refrigerants; VSK screw compressors and ELH scroll compressors can both be used with R513a.
