The Fysis natural refrigerant product lineup (R290, R600 and R600a) is poised to meet the growth in the refrigeration industry. These refrigerant products meet both AHRI and UL regulatory specifications as well as those for many major equipment manufacturers.


The EPA is mandating the phasing out of very high global warning refrigerants and HFC (hydrofluorocarbon) refrigerants in the U.S. by 2020. The development of alternative non-GWP (global warming potential) products such as HC (hydrocarbon) that prove to have a much less environment impact make for safer natural refrigeration solutions.

For the past 45 years, Aeropres Corporation has been on the forefront of developing and formulating low GWP natural hydrocarbon solutions for many industries. We now bring our tested, innovative solutions approach and supply chain to the refrigeration industry with our Fysis family of products.
Fysis can be supplied in a variety of formats to suit your needs from an assortment of cylinder sizes to bulk via railcar and truck trailers.
