The phase-out of high global warming potential (GWP) refrigerants has led to a shift towards alternative gases that meet both environmental and new safety standards. As environmental concerns and regulatory pressures increase, the industry faces significant challenges in selecting the most suitable refrigerants for cooling systems, balancing performance and equipment safety. One of the most discussed topics, when comparing low GWP refrigerants, is the flammability level and the associated regulations.
Frigel, a leading process cooling equipment supplier headquartered in Florence, Italy, and U.S. operations in East Dundee, IL, has made a strategic decision in its latest product offerings. Offering R-513A non-flammable, this choice reflects the company’s commitment to sustainability, safety and performance.
In chillers, the list of advantages for non-flammable R-513A over the alternative of mildly-flammable refrigerants, like R454B, are extremely important to understand the choice.
Frigel’s choice, R-513A, is a low-GWP refrigerant, maintaining an A1, non-flammable safety rating under the ASHRAE 34 Standard. In comparison, R-454B maintains an A2L, low flammability safety rating under the same standards. This fundamental difference in flammability and flame propagation has several effects for the design, operation and maintenance of chillers.
With its choice, Frigel offers a refrigerant that aligns with current and near-term environmental regulations without compromising on safety. As R513A is non-flammable, it reduces the risk of fire in the event of leaks or in situations where sparks may occur. This simplifies the design requirements and safety measures for the installation and operation of chillers.
Another significant advantage is the reduced complexity in maintenance and staff training. When handling a non-flammable refrigerant such as R-513A, technicians do not need special training that are required when handling flammable substances. This can reduce costs and minimize downtime during maintenance.
Chillers using R-513A offer a balance between energy efficiency, safety and sustainability, making them an attractive option for projects where safety is priority without compromising performance.
While R-454B offers a low-GWP solution, its mild flammability presents significant risks in environments where safety is paramount. Moreover, as regulations evolve, options like R-454B may face stricter scrutiny, making R-513A a more future-proof choice.
Frigel's decision to focus on R-513A is the result of a comprehensive evaluation of market demands, future regulatory expectations, technological innovations and the long-term safety implications for our customers. The choice of R-513A reflects Frigel’s commitment to provide a reliable non-flammable option that meets environmental and safety standards.
