  • Q Introduction of Refrigerant Gas R407c

    A Basic Introduction of Refrigernat Gas R407c

    R407c is a mixture of R32 refrigerant and R125/refrigerant plus R134a refrigerant in a certain proportion. It is an environmentally friendly refrigerant that does not destroy the ozone layer.

    R407C has very similar characteristics and performance to R22, so it has become a long-term alternative to R22 and is used in various air conditioning systems and non-centrifugal refrigeration systems.
    R407C can be used in the original R22 system without redesigning the system. It only needs to replace a few parts of the original system, and replace the mineral refrigerating oil in the original system with a lubricating oil (POE oil) that is miscible with R407C, and then it can be directly filled R407C, realize the environmental protection replacement of the original equipment.
    Since R407C is a mixed non-azeotropic working fluid, in order to ensure that its mixed composition does not change, R407C must be filled in a liquid state. If refrigerant leakage occurs in the R407C system and the performance of the system changes significantly, the remaining R407C in the system cannot be recycled and reused. The remaining R407C refrigerant in the system must be emptied and recharged with new R407C refrigerant.

    Application of Refrigerant Gas R407c

    R407C is a ternary non-azeotropic refrigerant introduced as a substitute for R22. In actual replacement, you only need to replace the lubricating oil, change its dryer and other minor parts. In order to improve the easy decomposition of ester oil into residues, additives are often added to the system. When in use, in order to give full play to its advantages, it is best to choose a counterflow heat exchanger. In addition, the area of the condenser and the flow rate of the cooling medium also increase. R407c also has the characteristics of cleanliness, low toxicity, non-combustibility, and good cooling effect, and is widely used in the air conditioning industry.

  • Q R407C Refrigerant Gas: A Comprehensive Overview for Importers and Wholesalers

    A
    As the global HVACR market continues to evolve, R407C has established itself as a critical refrigerant for specific applications. For importers and wholesalers looking to expand their product portfolio with a reliable, high-demand product, sourcing R407C from a trusted manufacturer is key. FRIOFLOR is positioned as that partner.
     
    What is R407C and Why the Market Demands It
    R407C is a non-ozone-depleting (zero ODP) HFC refrigerant blend composed of R32, R125, and R134a . It was developed as a primary alternative to R22 for existing and new air conditioning systems, heat pumps, and medium-temperature refrigeration equipment .
     
    Key Technical Features
    Composition: 23% R32, 25% R125, and 52% R134a .
     
    Performance: It has very similar properties to R22, making it the closest property match for retrofitting existing R22 systems in air conditioning applications . It is recognized as a "good replacement" for R22 in residential and commercial settings .
     
    Temperature Glide: As a zeotropic blend, R407C has a moderate temperature glide (approximately 10°F or 6°C). This is a critical factor for system design and requires technicians to charge the refrigerant as a liquid to maintain its proper composition .
     
    Lubricants: Systems using R407C require Polyol Ester (POE) lubricants. Retrofitting an R22 system requires flushing the existing mineral oil .
     
    Applications
    R407C is versatile and widely used in:
     
    Residential and Commercial Air Conditioning .
     
    Heat Pumps .
     
    Commercial Refrigeration and Chillers .
     
    The Market Opportunity
    The R407C market maintains a significant global footprint. The market is segmented by application (air conditioning, refrigeration, heat pumps, chillers), end-use industry (residential, commercial, industrial), and distribution channel, with wholesalers playing a pivotal role . Key markets include North America, Europe, and the Asia-Pacific region, with established demand in countries like the U.S., Germany, France, and the UK .
     
    The global R407C market includes major producers and distributors, and the aftermarket segment remains substantial . While long-term regulations like the Kigali Amendment are pushing for a global phasedown of high-GWP refrigerants, R407C maintains a strong market presence today in existing equipment and specific applications where low-GWP alternatives (like R454B or R452B) are not yet fully adopted or cost-effective . This presents a window of opportunity for wholesalers to source and distribute a product with robust installed-base demand.
     
    Why Source R407C from FRIOFLOR?
