After his grocery store burned to the ground in January 2023, Dan Craffey vowed to rebuild. He stuck true to his word and in January of 2023, Hunter’s Shop n’ Save in Wolfeboro, New Hampshire, was rebuilt larger, and with refrigeration in mind. The new store is 25% larger than its previous space at 16,000 square feet, and it features a brand-new refrigeration technology. The new technology, the FlexCube Supermarket Refrigeration System, was invented by Jim LaBrecque, a 50-year veteran of the supermarket industry, and an energy engineering expert. The FlexCube modular system consists of identical 2- by 2-foot cubes that not only take up no floor space, but are easy to install. Inside Hunter’s Shop n’ Save, the six cubes hang from the bar joist above the coolers. Each cube contains about 25 pounds of refrigerant each, and are suitable for both low- and medium-temperature applications, according to LaBrecque. They are also virtually leak-proof, and complies with federal regulations requiring lower-GWP alternatives as they use the A2L refrigerant R-454C.
