The phasing out of high Global Warming Potential (GWP) refrigerants has prompted the industry to consider alternative gases that adhere to new environmental and safety criteria.
As regulatory pressure mounts and environmental concerns grow, selecting appropriate refrigerants for cooling systems while balancing performance and safety becomes a critical challenge. Among the primary considerations when evaluating low GWP refrigerants is their flammability and related regulations.
Frigel's Refrigerant Options: R-513A and Propane
Based in Florence, Italy, the chiller manufacturer Frigel is set to introduce a new product line featuring two refrigerant choices - the non-flammable R-513A and the natural, flammable propane (R-290).
This strategic decision underscores the company's dedication to sustainability, safety, and performance, empowering customers to select solutions aligned with their specific requirements.
The Safety Advantage: Non-flammable R-513A
The benefits of non-flammable refrigerants like R-513A over mildly flammable options, such as R454B
The benefits of non-flammable refrigerants like R-513A over mildly flammable options such as R454B are critical for informed decision-making. R-513A holds an A1, non-flammable safety rating under the ASHRAE 34 Standard, contrasting with R454B's A2L low flammability rating.
This stark difference impacts chiller design, operation, and maintenance. Frigel's use of R-513A aligns with present and forthcoming environmental regulations without safety trade-offs.
R-513A reduces fire risks from leaks or sparks
By eliminating flammability, R-513A reduces fire risks from leaks or sparks, simplifying design and safety protocols for chiller installation and operation. Additionally, working with non-flammable R-513A reduces maintenance complexity and training costs, as technicians need not undergo specialized training for handling flammable substances.
While R454B may offer superior energy efficiency in certain scenarios, effective design can mitigate these differences, positioning R-513A chillers as efficient, safe, and sustainable options for projects prioritizing safety.
The Natural Option: Propane (R-290)
Propane, a natural hydrocarbon, offers an even lower GWP compared to R-513A, marking it as one of the most eco-friendly refrigerants. However, its flammability demands extensive safety measures during chiller design, production, and use.
Frigel is invested in creating systems that securely integrate propane, highlighting its environmental benefits despite the flammability challenges. By providing propane, Frigel enables customers to choose a refrigerant that supports global greenhouse gas reduction efforts.

Frigel's decision to emphasize R-513A and propane arises from a detailed analysis of market demands, regulatory standards, and technological progress.
R-513A's selection reflects a commitment to offering a dependable, non-flammable solution that satisfies current safety norms, while propane showcases their leadership in environmental sustainability.
Conclusion
Frigel's forthcoming chiller series signifies a pivotal advancement in merging environmental responsibility with safety. By presenting both R-513A and propane options, the company ensures customers receive innovative solutions meeting their safety or sustainability preferences.
As Frigel continues to innovate, they remain dedicated to delivering high-performance chillers that align with market values and evolving global needs.
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.
latest product line
Frigel, a pioneering chiller manufacturer based in Florence, Italy, has made a strategic decision in its latest product line, to be launched shortly, offering two distinct refrigerant options: R-513A non-flammable and R290 natural/flammable.
This choice reflects the commitment to sustainability, safety, and performance, ensuring that the customers can select the best solution for their needs.
The “Safety” Choice: Non-flammable R-513A
The large list of advantages of non-flammable over the alternative mildly-flammable refrigerants in chillers, as 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, R454B maintains an A2L, low flammability, safety rating under the same ASHRAE standards.
This fundamental difference in flammability and flame propagation has several implications for the design, operation, and maintenance of chillers. With this choice, Frigel offers a refrigerant that aligns with current and near-term environmental regulations without compromising on safety.
Effective and innovative design
As it is non-flammable, it considerably 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 that need to be implemented in 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 in handling flammable substances, which can reduce costs and minimize downtime during maintenance. In terms of performance, although R454B may offer greater energy efficiency in some applications, the difference in performance can be overcome through effective and innovative design.
They may conclude that, chillers using R-513A offer a balance between energy efficiency, safety, and sustainability, making them an attractive option for projects where safety is prioritized without compromising performance.
The “Natural” Choice: Propane (R-290)
Propane, a natural hydrocarbon, presents an alternative with an even much lower GWP than R-513A, making it one of the most environmentally friendly refrigerants available. However, its flammability necessitates rigorous safety measures in the design, manufacturing, and operation of chillers.
Frigel is committed to developing systems that safely accommodate propane, recognizing that the environmental benefits far outweigh the challenges posed by its flammability. By offering propane as an option, they provide their customers with a truly sustainable choice that supports global efforts to reduce greenhouse gas emissions.
The Decision Framework
Frigel's decision to focus on R-513A and propane was guided by a comprehensive analysis of market demands, regulatory requirements, and technological advancements.
The choice of R-513A reflects the commitment to providing a reliable, non-flammable option that meets current safety standards, while propane represents the dedication to leading the industry in environmental sustainability.
Conclusion
Frigel’s latest generation of chillers, to be launched soon, represents a significant step forward in balancing environmental responsibility with safety. By offering both R-513A and propane, they ensure that customers have access to cutting-edge solutions that meet their specific needs, whether they prioritize safety or sustainability.
As they continue to innovate, Frigel remains committed to delivering high-performance chillers that align with the values and the evolving needs of the global market.
