What is UL 117?

UL 117 refers to a technical standard that focuses on certain safety requirements for commercial refrigerators and freezers. It sets guidelines and criteria for manufacturers to ensure their products' safety, performance, and energy efficiency.

Safety Requirements for Commercial Refrigerators and Freezers

UL 117 encompasses various safety aspects for commercial refrigerators and freezers, covering electrical and mechanical components, insulation, refrigeration systems, temperature controls, and ventilation. Manufacturers must comply with these requirements to obtain UL certification for their products, ensuring that they meet the necessary safety standards.

Specifically, UL 117 addresses potential hazards such as electrical shocks, fire risks, and mechanical failures. It requires cabinets and doors to have proper insulation and structural integrity to prevent heat leakage and maintain temperature levels. Furthermore, the standard mandates proper labeling of controls and indicators, making them easy to read and understand for users.

Performance and Energy Efficiency

In addition to safety, UL 117 places emphasis on performance and energy efficiency. The standard sets criteria for temperature stability, cooling capacity, defrosting cycles, and recovery time after door openings. Manufacturers must ensure their refrigeration systems meet these requirements to provide optimal performance while minimizing energy consumption.

By adhering to UL 117, consumers can trust that commercial refrigerators and freezers are designed and manufactured to meet high safety standards. Moreover, conforming to the standard's performance and energy efficiency guidelines allows businesses to choose appliances that are both reliable and cost-effective in operation.

In Conclusion

UL 117 is a technical standard that establishes safety requirements, performance benchmarks, and energy efficiency criteria for commercial refrigerators and freezers. It helps ensure that these appliances are safe to use, reliable, and environmentally friendly.

Whether you are a consumer looking to purchase a commercial refrigerator or freezer, or a manufacturer aiming to comply with industry standards, understanding UL 117 is essential. By recognizing its significance and choosing products with UL certification, you can guarantee the quality and safety of these vital commercial appliances.
