COMPRESSORS - OUR PORTFOLIO
A HIGH-TECH PRODUCT THANKS TO CUTTING-EDGE TECHNOLOGY
We get gaseous media moving with virtually no wear, no external air supply and absolutely oil-free.
Our compressors ensure innovative and environmentally friendly mobility: thanks to maximum power density and controllable mass flows, they enable efficient operation of fuel cells. This reduces the number of layers required in the stack and optimizes hydrogen consumption. The additional turbine further reduces hydrogen consumption. The aim is to realize the complete fuel cell system in an even more cost-optimized way.
Our turbo compressors, which are designed in Switzerland, offer impressive performance in a compact system design. Space savings as well as low weight give more room for customer requirements. FISCHER compressors include a sophisticated electric drive and quickly bring the optimized compressor wheels to maximum speed. Our products have been designed with a spiral groove bearing system for long lasting operation in stationary or transportation applications.
Refrigerant compressors offer the following advantages
- Use of refrigerants with low global warming potential (GWP)
- High efficiency and COP
- Proven series technology from fuel cell air compressors
- Oil-free (gas lubrication with process gas)
- Greater robustness compared to conventional technologies
- Extended service life
- Higher power density
- Stepless adjustability
Air (R729) – The eco-friendly refrigerant with no compromises
Air (R729) is a natural refrigerant that meets the highest environmental and health standards. With a global warming potential (GWP) of 0 and an ozone depletion potential (ODP) of 0, it is a pioneer in sustainability and environmental compatibility.
R729 is used particularly in cryogenic applications, where it demonstrates its strengths in the so-called “reversed Brayton cycle.” By eliminating phase changes (liquid/gas) and leveraging the working medium’s high environmental compatibility, we offer an efficient, sustainable, and future-proof solution. Together, we are shaping a more environmentally friendly refrigeration technology.
Propane (R290) – The Natural and Highly Efficient Refrigerant of the Future
Propane (R290) is an environmentally friendly, natural refrigerant with an extremely low global warming potential (GWP = 3). Thanks to its outstanding properties, it is widely used in residential and commercial refrigeration systems as well as in modern heat pumps.
A key advantage of propane is its high energy efficiency, which not only significantly reduces electricity consumption but also contributes to the sustainable use of resources in the long term. With propane, we are committed to a forward-looking solution that perfectly combines environmental consciousness and performance.
Modular Platform Concept
Our modular platform concept combines standardized, proven core components with application-specific flexibility. The compressor stage, bearings, and motor form a common technological foundation that can be specifically expanded with various modules depending on customer and system requirements—for example, with a second compressor stage or a turbine.
This allows a single platform to give rise to various compressor variants that can be flexibly adapted to different pressure ratios, mass flows, and operating conditions. This reduces development effort and complexity, shortens development times, and simultaneously enables a high degree of customization and efficiency for the respective application.
