Polar King Unveils First Solar‑Assist Electric Refrigerated Trailer

Fort Wayne, IN – (Feb. 17, 2026) Polar King, a leader in cold storage, announces the launch of its Everest Edition walk-in refrigerated and freezer trailer, the industry’s first solar-assist mobile solution. 

The Polar King Everest Edition builds on the company’s proven all-electric foundation by integrating solar-assist technology designed to extend runtime, improve energy efficiency and enhance operational flexibility.

“Everest Edition represents the next evolution of electric refrigeration,” says Danny Gaviria, national sales manager for Polar King’s trailer division. “By integrating solar assist into our proven electric platform, we’re giving operators longer runtime, reduced charging dependence, and zero on-site emissions, all in a plug-and-play solution ready for real-world use.”

Polar King is debuting the Everest Edition refrigerated and freezer trailer at Trailer Tech Expo in Reno. The trailer is on display in Booth No. 235.

Solar Assist: A New Layer of Efficiency

At the core of the Polar King Everest Edition is a hybrid solar-assist and DC charging system engineered to supplement battery power and extend operational runtime. Solar panels help offset daily energy consumption, while primary DC charging ensures consistent, dependable replenishment.

Key features include:

• Solar assist charging to extend battery runtime
• Intelligent power management designed to prioritize battery health and uptime
• Battery-powered refrigeration for silent, zero on-site emissions operation
• No engine, no fuel and no mechanical generator

Rather than relying solely on solar, the system uses solar as an efficiency enhancer, supporting daily operation while maintaining the dependability of conventional DC charging when needed.

In addition to solar assist and DC charging, the trailer supports dual-voltage AC charging:

• 110V AC charging for convenient overnight charging from standard outlets
• 220V AC charging for faster recharge times where higher-capacity power is available

This flexible charging architecture allows operators to recharge at facilities, events, job sites or staging areas, while solar continues to support ongoing energy demands.

Proven Performance, Enhanced Capability

The Polar King Everest Edition rests on a 6’x12’ trailer platform and maintains all the same built-to-last characteristics of every Polar King over-the-road solution. The all-fiberglass interior and exterior keep internal products safe from external conditions. The Everest Edition maintains a 0°F to 50°F temperature range.

Manufactured in the Midwest, the new trailer is ideal for any cold storage application, from event and festival refrigeration to emergency response, remote job sites, agriculture, seafood and pharmaceutical transport.

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.
