Polar King Introduces Ursa Major Refrigerated Trailer for Critical Response Operations

Fort Wayne, IN – (Jul. 30, 2026) Polar King International, Inc. announces the launch of the Ursa Major, a purpose-built 6' x 20' refrigerated and freezer trailer engineered to deliver dependable mobile cold storage for emergency response, disaster recovery and other mission-critical operations.

Designed for first responders, emergency management agencies, disaster relief organizations, military operations, utility restoration crews and other critical response teams, the Ursa Major provides reliable refrigerated storage wherever food, water, pharmaceuticals, laboratory 

specimens and other temperature-sensitive supplies must remain protected.

"Critical response teams need equipment they can trust regardless of weather conditions, deployment location or mission requirements," said Andy Hogan, National Sales Manager for Polar King. "Whether supporting disaster response efforts, staging emergency supplies, preserving pharmaceuticals or providing refrigerated storage in remote locations, the Ursa Major is designed to help organizations maintain operational readiness when dependable refrigeration cannot be compromised."

The Ursa Major is a 6' x 20' refrigerated and freezer trailer with a temperature range of 0°F to 50°F, providing organizations with a versatile mobile cold storage solution that can be deployed wherever operations demand.

Built for the toughest operating environments, the Ursa Major features Polar King's signature seamless fiberglass interior and exterior construction combined with four inches of high-performance insulation. The one-piece fiberglass design resists rust, corrosion and deterioration while helping maintain consistent internal temperatures in extreme weather and demanding field conditions.

The Ursa Major also marks an important milestone as the first Polar King refrigerated trailer built on a Diamond C FMAX210 gooseneck trailer platform. The platform enhances towing stability, improved weight distribution and rugged transportation performance for organizations operating in demanding field conditions.

To simplify deployment, the trailer features an integrated aluminum slider ramp with hydraulic lift assist, allowing personnel to load and unload supplies quickly and efficiently. Additional heavy-duty features – including a slipper roller suspension system, cushion coupler and 14-ply tires – help ensure dependable performance wherever the mission takes it.

The Ursa Major is available now.

About Polar King International 

The introduction of the Polar King outdoor walk-in freezer into the food service industry resulted from three generations of walk-in refrigeration technology and experience. Polar King’s fiberglass, one-piece walk-in cooler is the natural evolution of the walk-in cold storage 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 demand grew for outdoor fiberglass commercial walk-in coolers and commercial walk-in freezers, production was moved to a 251,200 sq. ft. facility located in Fort Wayne, Indiana. For 40 years, Polar King has provided thousands of walk-ins to single-unit operators, chain restaurants, schools, health care facilities, government agencies, and many other industries requiring dependable outdoor walk-in refrigeration.
