Polar King, a leading provider of refrigerated and freezer trailers, announces the launch of the PKM620, a 6-foot by 20-foot trailer – the largest mobile cold storage walk-in unit in the industry.  

Built with Polar King’s signature fiberglass, seamless construction, the PKM620 offers a sanitary, durable cold storage environment capable of reaching sub-zero temperatures. Unlike other trailers in the Polar King lineup, the new unit features two full-sized doors, giving operators faster, safer and more efficient loading and unloading for high-volume operations. In addition to the backdoor, there’s also a door on the side of the unit. 

“The PKM620 represents a bold step forward in mobile cold storage,” said Danny Gaviria, national sales manager for Polar King’s trailer division. “It combines the size and capability our customers have been asking for with the energy efficiency and reliability Polar King is known for. We’re proud to add this massive unit to our standard line of trailers, and we know it will help customers from day one.” 

Polar King offers refrigerated and freezer trailers designed specifically for outdoor, over-the-road use. The trailers are made in America and feature a 100% seamless fiberglass exterior design that ensures a sanitary internal environment that remains independent of external temperatures.  

The refrigerated and freezer trailers are certified by the NSF, as well as by the National Association of Trailer Manufacturers (NATM). Polar King is also ISO compliant, ensuring the units meet stringent safety, manufacturing, and regulatory standards. 

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.
