The U.S. and Canadian markets enforce strict regulations for commercial refrigeration equipment—refrigerator, display refrigerator, display freezer, fridge, and freezer—to protect consumer safety and the environment. Environmentally, the EPA bans high-ODP refrigerants (e.g., R134a), requiring low-GWP alternatives like R290, while states like California (Title 20) and New York enforce strict energy efficiency rules.ETL certification (administered by Intertek) is critical for market access. Aligned with UL 471 (U.S.) and CSA C22.2 No. 120 (Canada), it covers safety, energy, and material compliance, and is recognized in both countries—avoiding the need for dual certifications. For manufacturers and buyers, ETL simplifies entry to North America’s high-stakes market.
