[3] Frustrated by iceboxes, the Grand Rapids Refrigerator Company introduced a porcelain-lined "Leonard Cleanable" ice cabinet.

Customers could choose from several different home designs, all of which were equipped with climate control systems and the latest electric appliances, and were advertised to cost about $7,500 ($151,523 in 2022) [6] for a six-room house.

From simple merchandising of the products of the American factories, it grew until it was producing much of its own equipment for the British market.

[12] The merger took effect on January 4, 1937, to form Nash-Kelvinator Corporation as part of a deal that placed George W. Mason at the helm of the combined company.

With the exception of one-ton, two-wheeled truck cargo trailers and some refrigerators, Nash-Kelvinator did not manufacture products related to its pre-war operations.

[13] Other wartime products included three- and four-blade propellers, optical equipment and binoculars as well as Pratt & Whitney R-2800 Double Wasp radial aircraft engines.

[13] The Kelvinator refrigerator facility in Grand Rapids, Michigan, had up to 5,000 employees when it produced airplane propellers and engine parts.

[15] In Britain, Kelvinator of London contributed to the field of testing airplane components at ultra-low temperatures, and instruments under high altitude conditions, research that was credited as saving the lives of many Allied aircrews.

[17][18] Kelvinator refrigerators included shelves on the inside of their doors and special compartments for frozen juice containers in the freezer.

[17][19] In the 1960s, Kelvinator refrigerators introduced "picture frame" doors on some models allowing owners to decorate their appliance to match décor of their kitchens.

Kelvinator joined White Consolidated Industries, a company that later acquired the rights to Frigidaire (originally owned by General Motors), Gibson, and White-Westinghouse product lines.

[21] The Kelvinator brand is used in Argentina for a wide variety of appliances marketed by Radio Victoria Fueguina in Tierra del Fuego.
