MORRIS TOWNSHIP, N.J. — Honeywell Intl. Inc. announced that leading global compressor manufacturers Emerson Climate Technologies Inc., Bitzer, and Frascold have approved Honeywell’s low-global warming potential (low-GWP) refrigerants Solstice N40 (R-448A) and Solstice N13 (R-450A) for use in their commercial refrigeration compressors following an extensive evaluation.

Solstice N40 and N13 are replacements for widely used higher-GWP refrigerants used in supermarkets and commercial refrigeration equipment. The new products, which are based on hydrofluoroolefin (HFO) technology, have GWPs that are at least 60 percent lower than the refrigerants they are designed to replace, which are based on hydrofluorocarbon (HFC) technology. The new refrigerants are also more energy efficient.

“We are very pleased that Emerson, Bitzer, and Frascold have completed their testing and approved Solstice N40 and N13 for use in their commercial refrigeration compressors. We see this as a major step forward in helping the industry comply with the European Union’s F-Gas regulation,” said Julien Soulet, managing director for Honeywell Fluorine Products in Europe, Middle East, Africa, and India. “Both of these HFO blends have already been tried and tested in many different applications and are commercially available throughout Europe.”

Solstice N40 (R-448A) is an HFO blend for low- and medium-temperature refrigeration equipment including supermarket freezer cases or transport refrigeration. It’s designed to replace R-22 and R-404A for both new equipment and retrofits and offers a GWP that is 66 percent lower than R-404A. In supermarket trials conducted in the U.S. and Europe, Solstice N40 demonstrated 3 percent lower energy consumption in low-temperature applications and 5-16 percent lower energy consumption in medium-temperature applications when compared to R-404A.

Solstice N13 (R-450A) is an HFO blend for chillers in medium-temperature applications such as supermarket display cases and self-contained refrigeration units that require a nonflammable refrigerant solution. Solstice N13 is designed to replace R-134a and offers a GWP that is 60 percent lower than the GWP of R-134a. In laboratory and supermarket trials, Solstice N13 demonstrated more than 3 percent lower energy consumption in medium temperature applications when compared to R-134a in the same ambient temperature and humidity conditions.
