Back in 1961 company founders: George Johnson, Duke Wegner, and K Hirata had a dream of starting their own business. They didn't have much money, but together they had 50 years of refrigeration experience and a strong will to succeed. They named their new company Zero Zone, and began operations in a rented dairy barn in Pewaukee, Wisconsin with a pledge to "build the best freezers in the business at a competitive price". Zero Zone soon became one of the first to utilize energy-efficient glass doors in self-contained reach-ins. It was this pioneering spirit that made the company a leader in case innovations, including the introduction of 1,500 milliamp vertical lighting for improved product visibility.
