  • 12 Year Complete Structural Warranty
  • Cuts Operating Costs
  • Lowers Power Bills
  • Reduces Maintenance/Repair Costs
  • Eliminates Construction and Replacement Costs

The patented process for constructing our energy efficient walk-in cooler 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. Every Polar King comes with a 12-year complete structural warranty ensuring you superior durability even in the worst of weather conditions.

The Polar King walk-in is designed to save you money by being as energy efficient as possible, 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.

When choosing a Polar King outdoor walk-in, you have the flexibility to choose a thru-wall or freestanding unit. Thru-wall installations allow the operator to place the unit outdoors while providing the convenience of accessing the unit from indoors. Freestanding units on the other hand, are stand alone units that are not attached to the building and are accessed from outside.

The type of unit that is right for you will depend on how you intend to use the walk-in or what type of an operation you have. In many cases, a freestanding unit can later be used for a thru-wall application and vice-versa.

Whether you need a cooler, freezer or combination of both, a Polar King walk-in will save inside space and increase your buying power. Every Polar King unit allows you to design your own floor plan and enables you to locate doors and walls virtually anywhere. This flexibility provides foodservice operators unlimited storage opportunities ideally suited for their application.

Freestanding and thru-wall units come in a wide range of sizes and variations. You can get your Polar King in widths from 6′ to 16′ and in lengths up to 60′. Before you plan to expand, consider the savings a Polar King will provide.

Humidity Control Systems

At Polar King, we recognize that the perfect combination of humidity and temperature control is critical in a number of industries. Incorrect humidity levels and fluctuating temperatures can cause spoilage, damage products, and significantly decrease shelf life. We can design a system that provides a variety of different humidity levels and have multiple systems to add and remove moisture.
