The patented process for constructing the Polar King walk-in refrigerated trailers incorporates urethane insulation completely encased in fiberglass, both inside and out. This method provides superior structural strength since it forms a one-piece structure. There are no seams on a Polar King unit; therefore the structure remains completely intact so air and moisture cannot deteriorate the insulation.

One-piece seamless construction allows the unit to be set outside without the use of a roof cap or any other type of expensive protection. The walk-in is completely weatherproof and requires no assembly.

Polar King walk-ins are designed to save you money by cutting operating costs, lowering power bills, reducing maintenance/repair costs and eliminating construction and replacement costs. Polar King uses fiberglass, so you never have to worry about rusting, denting or corroding, and you can be certain that your unit will always look factory new with regular care and cleaning.

To top it off, every Polar King trailer comes with a 1-year complete structural warranty ensuring you superior durability even in the worst of weather conditions.  If you’re looking for a long or short term lease on a refrigerated trailer, that is an option for you as well.

On the go, Polar King trailers accompanied by a generator are great for short haul deliveries, as well as emergency relief after natural disasters. These mobile trailers are often an excellent alternative to refrigerated straight trucks, as they can be shared by multiple vehicles and can operate with an electrical connection when not in transit.

Available in standard 6’ x 8’ single axle, 6’ x 12’ dual axle and many custom sizes, these trailers can be configured as coolers and/or freezers. Many of which operate on a 120V electrical connection.

“In order to expand our catering sales, we realized it would make sense to buy our own trailer and we haven't looked back since. I have no doubt that investing in our trailer has been beneficial to our catering business and I would highly recommend Polar King as a reputable company that builds a great refrigerated trailer.”
