We Are Now R290 Compliant

Structural Concepts has converted its self-contained refrigerated merchandisers well ahead of the 12/31/2024 EPA deadline. With the R290 system, fresh food operators will experience a quieter operation, a reduction in daily energy consumption, and a future proof solution that complies with EPA requirements.

R290 Refrigeration Systems

After 11/1/2024, all non-R290 refrigeration systems will be unavailable. For some models where dimensional changes occurred, new models will replace the existing non-R290 models.

Be Confident That the Equipment You Are Purchasing is Now R290 Compliant and Will Arrive On Time

Our new common, now available R290 compliant designs and robust components provide further peace of mind that you’ll experience consistent trouble-free operation – and our industry-best lead times will ensure immediate product availability and on-time delivery. 

What Is Structural Concepts Doing To Ensure A Seamless Conversion

In partnership with NIDEC, we innovated single and multi-circuit refrigeration systems using less than 150g of R290 that emphasize efficiency for daily energy savings.  

We conducted a full product line conversion from Hydrofluoroolefins (HFO’s) to low charge R290 variable speed technology; Single and multi-circuit systems using less than 150g of R290.

With the majority of cases transitioning to NSF Type II (operating in environments that don’t exceed 80° F and 55% relative humidity), we’re already prepared with our innovative Breeze-E refrigeration system. An easy-to-maintain, slide-out refrigeration system that’s designed with a variable speed compressor, smart microprocessor, and an oversized condenser coil to ensure a longer life and stronger overall performance providing the benefit of holding product-safe temperatures in warmer, more humid operating environments 

The R290 condensing unit with variable speed compressor smartly optimizes energy consumption by managing compressor on and off cycles. The onboard condensate pan provides a completely self-contained solution that is fully operational once the unit is plugged in.

Frequently Asked Questions
The AIM Act (American Innovation and Manufacturing), enacted on December 27, 2020, authorizes the U.S. Environmental Protection Agency (EPA) to address hydrofluorocarbons in three main ways: 1) phasing down their production and consumption, 2) promulgating certain regulations for purposes of maximizing reclamation and minimizing releases of HFCs from equipment and ensuring the safety of technicians and consumers and 3) facilitating the transition to next-generation technologies through sector-based restrictions. The EPA’s final rule in the Technology Transition Program focuses on the third area—the transition to substitutes through sector-based restrictions. The final rule, signed October 5, 2023, restricts the use of higher GWP HFCs in new aerosol, foam, and refrigeration, air conditioning and heat pump products and equipment. In most subsectors, the EPA has set a maximum GWP limit on HFCs or HFC blends that can be used. The rule operates by: • Prohibiting the manufacture and import of products that use higher GWP HFCs • Prohibiting the sale, distribution and export of those products three years after the manufacture and import restriction, and • Prohibiting the installation of new heat pump systems that use higher GWP HFCs. Compliance dates and GWP limits vary based on sector (refer to full final rule). For self-contained refrigeration for the retail food subsector, the manufacture and import compliance date is January 1, 2025.
R290 is a hydrocarbon refrigerant consisting of propane, with a chemical formula of C3H8. It belongs to the category of natural refrigerants, which are substances that occur naturally in the environment and have minimal impact on global warming and ozone depletion. R290 has gained popularity as an alternative to synthetic refrigerants due to its excellent thermodynamic properties and low environmental impact.
Commercial Refrigeration: R290 is commonly used in commercial refrigeration systems, including supermarket refrigerators, display cases, and cold storage facilities. Its efficient cooling properties make it suitable for maintaining optimal temperature conditions for food preservation.
Environmental Sustainability: By choosing R290 refrigerant, businesses and consumers can significantly reduce their carbon footprint and contribute to environmental conservation efforts. Its low GWP and ozone-friendly properties align with global initiatives to combat climate change and preserve the ozone layer. Energy Efficiency: R290’s superior thermodynamic properties translate to enhanced energy efficiency in refrigeration and air conditioning systems. By maximizing cooling performance while minimizing energy consumption, R290 helps lower operating costs and promote sustainable practices. Regulatory Compliance: With stringent regulations governing the use of synthetic refrigerants, R290 offers a compliant alternative for businesses seeking to adhere to environmental standards. Its natural composition and eco-friendly credentials make it an attractive choice for industries striving for sustainability.
While R290 is considered safe for use in refrigeration applications, proper handling and storage procedures are essential to mitigate potential risks. Here are some key safety considerations: Flammability: R290 is a flammable substance and should be handled with caution to prevent fire hazards. Installers and technicians must adhere to safety guidelines and use appropriate equipment to minimize the risk of ignition. Ventilation: Adequate ventilation is crucial when working with R290 to prevent the accumulation of flammable vapors in enclosed spaces. Proper ventilation systems should be in place to ensure a safe working environment for personnel.
