For Class l, Groups C and D hazardous locations. Meets NFPA Standards as found in Articles 500-501. In addition this refrigerator is corrosion resistant. Aluminum or epoxy coated refrigeration components are susceptible to attack by caustic materials and strong acids. These components will corrode then begin to leak, allowing Freon to escape. This inevitably causes the compressor to fail. This Corrosion-Resistant unit solves this problem by replacing aluminum components with stainless steel condensing coils, evaporators and shelves. This 20 cubic foot unit has a temperature range from -5° to 15°C (23° to 60°F) so the unit can be used as a freezer or a refrigerator. Unit has porcelain enamel interior and stainless steel door liner for improved corrosion resistance over ABS plastic or enameled steel. Overall: 32W x 33D x 71-1/2H . For 110V, 60 Hz.(3560A)
