U.S. Cooler is proud to manufacture walk-in coolers and freezers that not only meet but exceed the energy efficiency standards set forth by the U.S. Department of Energy (DOE) under the Energy Independence and Security Act (EISA). As regulations evolve to promote better energy usage and lower environmental impact, U.S. Cooler remains committed to delivering high-performance, compliant solutions without compromise.
Understanding DOE and EISA Requirements
The DOE’s EISA regulations were developed to improve energy efficiency for walk-in coolers and freezers (WICFs), setting minimum standards for components such as doors, panels, and refrigeration systems. These rules are legally binding and apply to manufacturers of walk-in units with an internal volume of 3,000 square feet or less, operating at temperatures of 55°F or below.
The performance standards, which have taken effect in phases beginning in 2009, cover three major component areas:
- Doors: All walk-in doors must meet specific U-factor insulation requirements and be equipped with automatic closers.
- Panels: Insulation must meet minimum R-value thresholds—R-25 for coolers and R-32 for freezers (based on ASTM C518 at 75°F).
- Refrigeration: Systems must meet energy performance standards, depending on system type and application.
How U.S. Cooler Exceeds Expectations
U.S. Cooler goes beyond the minimum requirements in both product performance and customer confidence. Independent third-party testing has confirmed that U.S. Cooler panels not only comply with DOE standards—they exceed them.
Highlights of U.S. Cooler Compliance:
- Panels tested with 4″ thickness achieved R-values above the DOE minimums for both coolers and freezers.
- Door assemblies incorporate high-efficiency insulation, self-closing hinges, and magnetic gaskets for a secure, energy-saving seal.
- We offer refrigeration systems that meet or exceed current DOE and EISA requirements, including energy-efficient options for both indoor and outdoor applications.
By exceeding federal guidelines, U.S. Cooler products help businesses reduce energy costs, comply with government standards, and support environmental responsibility.
