Global natural and organic foods retailer Whole Foods Market will utilise Honeywell’s Solstice® N40 (R-448A) lower global-warming-potential (GWP) refrigerants in its US store.

The installation is planned for more than 100 Whole Foods stores as part of an effort to reduce refrigerant emissions under the US Environmental Protection Agency’s GreenChill programme.

Based on hydrofluoroolefin (HFO) technology, Solstice N40 offers a GWP that is approximately 68% lower than legacy hydrofluorocarbon (HFC) refrigerants like R-404A.

When using Solstice N40, refrigeration systems also consume less energy than their counterparts that cool using HFCs. In US and European supermarket trials, in comparison to R-404A, Solstice N40 demonstrated an average of between 5 to 15% lower energy consumption in refrigeration applications.

“In the past decade, we’ve implemented several innovative measures to reduce our CO2 emissions, and the use of Honeywell’s refrigerant to retrofit our stores will contribute significantly to this goal,” said Mike Ellinger, Principal Program Manager-Engineering, Compliance and Sustainability, of Whole Foods Market.

“After reviewing all of our available retrofit options for our refrigerated cases, R-448A was the clear winner, based on its performance, energy efficiency, reduced GWP and ease of conversion.”

Chris LaPietra, Vice-President of Honeywell Stationary Refrigerants, added, “Solstice N40 has become the trusted choice for both commercial and industrial refrigeration customers globally to meet sustainability goals, and we are proud to assist the industry in moving toward the future with environmentally preferable and energy-efficient refrigerants.”

“Solstice N40 will help Whole Foods Market lower its carbon footprint, save energy and meet regulatory requirements without having to undertake massive changes to its systems.”
