Seamless Fiberglass
Walk-in Coolers & Freezers

Fiberglass Advantage

Withstand the Elements

Sun

A seamless exterior assures economical operation even in the most intense heat. Tested above 175°F, Polar King's fiberglass design is the perfect fit for warm weather climates.

Rain

The inherent strength of fiberglass allows a Polar King unit to withstand blowing debris and abuse associated with heavy thunderstorms.

Salt

Saltwater can be a real challenge for operations near the coast, especially when dealing with a metal walk-in. Because fiberglass does not rust, dent or corrode, this problem is eliminated.

Snow

Even heavy snow is no match for a Polar King. The roof can be rated to withstand a snow load of up to 100 lbs. per sq./ft. Because of Polar King's construction, there is no need for steel framing.

Polar King walk-in refrigeration units are designed and engineered specifically for outdoor use. Every unit is built to withstand the elements and to maintain its efficiency as outdoor conditions change. With thousands of units being used across the country and around the world, Polar King units offer worry-free operation under the worst conditions. From the intense sun of Arizona to the bitter cold of Minnesota; no climate is stronger than a Polar King.

Polar King's 100% seamless fiberglass design provides a continuous surface which keeps the insulated structure completely intact; free of moisture damage and bacteria formation. Plus, all of the interior corners are rounded to further ensure a sanitary environment. The NSF approved flooring system provides a non-slip durable finish; which greatly reduces the risk of slips and falls. With the unit being completely seamless, it can easily be cleaned with a hose; without damaging the insulation.

Compare Us

Comparing walk-in refrigeration units can be a tedious exercise, as most walk-ins on the market are very similar and are constructed of insulated foam panels sandwiched between two pieces of metal. However, when compared to Polar King’s patented fiberglass construction, the comparative difference has been very clear for over 25 years.

Outdoor walk-in coolers and freezers operate under a high temperature differential (TD), making resistance to heat and moisture critical factors to consider when choosing an outdoor walk-in. The materials and design used to build the walk-in will dictate the unit’s ability to offer long-term reliable operation.

Polar King’s fiberglass exterior design absorbs very little heat because of its natural properties against conductivity. Conventional metal and steel exteriors are actually conductors, thus absorbing and storing much of the heat. This requires the refrigeration system to work overtime; causing maintenance issues, increased electricity consumption and ultimately reducing its longevity.

In a comparative analysis, Polar King proves to be far superior to Aluminum and Steel at only 0.04 BTUs.

We have been so happy with our new walk-in. The glass display doors that we have has helped make product rotation very simple. Even the health department complemented the walk-in. Thanks again for a job well done.
