U.S. Cooler Saves Customers Money with Energy Efficient Walk-ins

Most walk-in coolers and freezers are purchased based upon the initial cost. What many fail to realize is that operational costs can dig deep into consumers’ pockets. U.S. Cooler is giving the Cold Storage Industry an energy efficient option by manufacturing walk-ins with extruded polystyrene insulation.

Extruded polystyrene is the most efficient insulation available on the market. Over time, extruded polystyrene resists moisture while other insulations start absorbing it. One must consider a real life application to understand moisture absorption.

Freezers normally operate at -10° F inside, but may have an exterior temperature of up to 95° F or even more. With the extreme difference in temperatures, the insulation is vulnerable to retaining moisture in the structural voids. When water starts collecting inside walk-in insulation, the R-value drops and moisture inside the insulation starts to freeze.

When moisture is absorbed and R-values start to decrease, refrigeration systems start working harder and longer to make up for the heat transferring into the walk-in. A refrigeration system working overtime means higher energy bills. By using extruded polystyrene, consumers can save that money.

Extruded polystyrene is unique; the insulation is a closed-cell product, meaning the cells of the material are so tightly packed together that moisture has a difficult time penetrating, which is optimal for moisture resistance and keeps the R-value from decreasing.

Using studies performed by the U.S. Army Corps of Engineers (CREEL), U.S. Cooler demonstrated extruded polystyrene saved consumers over $5,000 in energy costs over the first five years of operation. The savings again are due to extruded polystyrene’s ability to resist moisture and to retain its R-value better than other insulators.
