KEY FEATURES
Reliable performance, proven efficiency
Our exclusive construction process starts with premium 4" polyisocyanurate rigid board insulation, rated at a R-value of 28, completely enveloped in durable fiberglass. This one-piece construction increases the strength of the structure, protecting the insulation from air and moisture and creating a smooth, continuous surface inside and out. Unlike panel-built alternatives, which can create "hot spots" at every seam, Polar King commercial walk in coolers maintain consistent temperatures throughout the entire chamber The structures arrive ready to operate without the added cost of onsite assembly and effectively increase your building’s usable indoor space when you relocate cold storage outside. Our commercial walk in coolers are incredibly efficient, reducing maintenance and repair costs, cutting power bills, and eliminating construction costs.
Standard equipment
The most well-equipped walk ins on the market
All Polar King commercial coolers come equipped with the features our customers rely on most, installed in our facility before delivery. For a full listing of everything included, check out the spec sheets for each model.
Warranties that back our engineering
We’re so confident in our design and superior build quality that we offer these unmatched warranties: 25 years for the internal foam structure, 12 years for the physical structure, 5 years for the compressor, 1 year for parts and accessories, and 1 year for the refrigeration system & components.
Fiberglass surface
A smooth fiberglass surface completely encapsulates and protects the rigid board insulation, creating an extremely durable one-piece unit that won’t dent, rust, or corrode. The crevice-free material is NSF approved and anti-microbial, making it easy to sanitize.
Factory-installed refrigeration
Unlike panel boxes that typically require contractors to assemble, Polar King commercial coolers ship pre-built and tested in the factory with a 208-230/1/60 refrigeration system, eliminating the expense and potential errors of onsite assembly.
Exterior color options
Our commercial walk in coolers come standard with a one-color finish of your choice. You can choose from a selection of colors, or we can match the color of your existing building from a sample or a paint code from a national paint manufacturer.
