Special Use & Explosion Proof

Years of experience and expertise has allowed Polar King to expand manufacturing methods to many items outside of the standard commercial walk in refrigeration applications. And the number of projects we build for specialty use continues to expand on an annual basis. We can also provide freezer and cooler storage units for hazardous (classified) locations. Whether you need a standard explosion proof freezer unit or a customized freezer unit, we can meet all of your commercial walk in refrigeration requirements.
