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.

Teperature Differential
Outside Temp > Inside Temp
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.
How does this effect
the inside temp?
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.
