Polar King International, Inc. is the industry's #1 manufacturer of outdoor fiberglass walk-in freezers and walk-in coolers . Our walk-in refrigerators are made of fiberglass and designed specifically for outdoor use. All outdoor cooler units are delivered pre-wired, pre-assembled, and ready to operate. No on-site assembly is required on any walk-in or trailer unit. The introduction of the Polar King outdoor walk-in freezer into the foodservice industry is the result of three generations of walk-in refrigeration technology and experience. Polar King’s fiberglass, one-piece unit was the natural evolution of the walk-in industry from the conventional metal panel constructed unit. In early 1982, Polar King began operations by constructing and shipping walk-ins from a modest 12,000 sq/ft. facility in New Haven, Indiana. As the demand for outdoor fiberglass coolers and freezers continued to grow, production was moved to our current 100,000 sq/ft. facility located in Fort Wayne, Indiana. For nearly 30 years, Polar King has provided thousands to single unit operators, chain restaurants, schools, health care facilities, government agencies and many other industries requiring dependable outdoor walk-in refrigeration.
