Temperature Zoning Made Easy

The American Society of Heating, Refrigeration, and Air Conditioning Engineers (ASHRAE), concluded that "infiltration air heat gain and associated equipment related load can amount to more than half the total refrigeration load of distribution-type warehouses and similiar applications."

It's a fact that air exchange will occur because of normal air density. As warm air rises and flows into the freezer at the top of the door opening, the cold freezer air escapes at the bottom of the doorway.

The InsulAir™ Cold Storage Door is a major step towards eliminating cold storage door problems. In most applications, it provides a measurable improvement in all areas over conventional doors. Your factory-trained Randall Manufacturing representative can evaluate the expected performance based upon your specific application requirements.
