As higher-GWP refrigerants continue to be phased out, the evaluation and approval of alternative refrigerants increase in importance.

At a time when legacy hydrofluorocarbon (HFC) refrigerants are being phased out due to their high global warming potential (GWP), R-290 has emerged as an increasingly viable low-GWP alternative. Offering excellent thermodynamic properties and a very low GWP (GWP = 3), this natural hydrocarbon refrigerant has potentially widespread uses in commercial refrigeration. With a GWP of 3 and an ozone depletion potential (ODP) of 0, R-290 poses virtually no threat to the environment.

Making the case for R-290 sustainable refrigeration solutions

The prospect of increasing charge limits has expanded R-290’s potential in commercial refrigeration applications. Small-charge, self-contained refrigeration systems have become much more commonplace in U.S. food retail and foodservice markets. R-290’s highly efficient, eco-friendly performance makes it an ideal choice for customers seeking to achieve their corporate sustainability objectives or comply with ever-increasing refrigerant regulations.

Although R-290 offers proven sustainability and performance benefits, its A3 “higher flammability” classification must be taken into consideration. To mitigate R-290 safety risks and address safety concerns, the governing bodies that regulate the safe use of refrigerants in the U.S. have long established a 150 grams (5.3 ounces or 0.33 pound) maximum charge limit. The revised standard approved higher charge limits that potentially could expand the size of R-290 cases, raising the charge limits on commercial self-contained, plug-in displays.

OEM refrigerant journey leads to next-gen R-290 equipment platform

Like many commercial refrigeration original equipment manufacturers (OEMs), the transition to lower-global warming potential (GWP) refrigerants had long been on FBD’s product development radar. As a leading manufacturer of frozen beverage dispensers — such as those used by major restaurant and convenience store chains, theme parks and beverage brands — FBD began evaluating its lower-GWP refrigerant options.

FBD collaborated with Copeland to align compressor platforms with its next-gen refrigerant selections, and moved forward with new product prototypes. The R&D team selected R-290 as its primary option.

The refrigeration industry’s primary concern is complying with new and upcoming regulations. At Copeland, our focus is unequivocal: nearly every internal development program we’ve undertaken in commercial refrigeration has been geared toward achieving this compliance. And one of the solutions we’ve researched, tested and implemented in our products is R-290.
