Energy (and money) Saving Tips for Your Walk-in

steel walk-in coolerHere are some ways to help you save energy costs on your walk-in refrigerator or walk-in freezer.

  • Properly seal all penetrations in walk-in.
  • Replace worn or damaged door seals.
  • Periodically, check gaskets between panels to make sure they are not cracked or weathered. If so, check with your local health codes for the correct procedure to follow as far as repair and replacement.
  • Do not prop door open for an extended period of time.
  • Add strip curtains or air curtains to your walk-in for extra protection from air infiltration when door is open.
  • Make sure the lights are off when exiting the walk-in. Lights produce heat, which will cause your unit to run more to hold its optimal temperature.
  • Make sure there is nothing stacked around the coil to restrict airflow.
  • Make sure fan motors are balanced and running at optimum speed. Clean fan blades to reduce drag.
  • Use an evaporator with an EC Motor.
  • Install refrigeration away from doors.
  • Keep condenser coils clean.
  • Utilize Smart Defrost Kits.
  • Set defrost frequency at minimum requirements.

Cooler Insulation- Extruded Polystyrene Vs. Polyurethane

U.S. Cooler manufactures walk-in coolers and freezers employing both Polyurethane and Extruded Polystyrene. Through testing and years of experience we maintain that extruded polystyrene insulation is superior for use in walk-in coolers and freezers. Polystyrene has many characteristics that prove it to be the best insulation material for walk-ins. The two main insulating foams found in walk-ins are Extruded Polystyrene and Polyurethane. Each insulation has differentiating characteristics and should be optimized for the specific application.

Polystyrene is a dense closed-cell structure that is very resistant to moisture and holds its R-Value longer than other competing insulations found in walk-ins, such as Polyurethane. This allows less water infiltration in the insulation, which in turn saves energy and money. When water starts seeping into the insulation’s pores, the R-value drops dramatically causing the refrigeration to work harder to hold its respective temperature. Refrigeration working overtime means higher energy bills. Polystyrene is less water vapor permeable; therefore, water vapor does not infiltrate through the material as quickly or easily as it does other insulating materials.Using studies performed by the U.S. Army Corps of Engineers (CRREL), 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.

Polystyrene used in walk-in coolers and freezers is made from “at least 20% pre-consumer recycled polystyrene.” (Owens Corning, Technical Bulletin: Recycle Content Claims Must be Reliable and Verifiable) Polystyrene found in walk-ins is also 100% recyclable. Manufacturing companies that produce these insulation materials, reproduce the resources in new insulation material. Alternatively, it is important to note that Polyurethane is produced from chemicals and is not made from any recycled materials nor can it be recycled or reused.

Polystyrene in walk-in coolers and freezers is the most cost effective and environmentally friendly insulation used in walk-ins today. Not only is polystyrene in walk-ins made with recycled materials and is 100% recyclable but it is energy efficient and can save a great deal of money in energy costs and reduce carbon footprint over the life-cycle of the walk-in.

Heart to Heart Cold Storage Unit

Heart to Heart International Inc., a leading global humanitarian organization, has installed a U.S. Cooler cold-storage unit on Saturday, January 24, 2009, at its Global Distribution Center in Kansas City, KS. The 14,000—cubic-foot, refrigerated unit is expected to store life-saving medications, such as insulin, for Heart to Heart’s local and global health initiatives. Much of the hardware and labor was donated by local businesses.
“Without the support of several charitable companies, this day might never have come,” said Jon D. North, Heart to Heart’s CEO. “Now we can deliver life-saving medicines requiring cold storage more efficiently to under served people in Kansas City, in the United States and almost anywhere in the world.”
U.S. Cooler is very gracious for the opportunity from CFM Distributors to contribute to Heart to Heart’s mission.
