Refrigerant R-507

Refrigerant R-507 is an azeotropic blend composed of R125 and R143a in a 50:50 ratio. Classified as a hydrofluorocarbon (HFC) refrigerant, it exhibits outstanding refrigeration performance at medium and low temperatures, making it an ideal replacement for R502 refrigerant. Its CAS number is 95648-07-2 (mixture), UN number is 3258, and it is classified as a non-flammable, non-toxic gas under Class 2.2 of the dangerous goods classification. Product attributes: R-507 refrigerant is a colorless, odorless gas with an ODP value of 0 and a GWP value of 3985. Despite its relatively high GWP, it offers irreplaceable advantages in medium-to-low temperature refrigeration applications and complies with current global environmental regulations.

Core parameters include a boiling point of -47.1°C at standard atmospheric pressure, a critical temperature of 70.9°C, a critical pressure of 3.79 MPa, and a saturated vapor pressure of 1.7 MPa at 25°C. Purity is ≥99.8%, moisture content ≤0.001%, and acidity ≤0.00001%. Functionally, R-507 refrigerant offers high refrigeration capacity, minimal temperature slip (azeotropic properties), and stable operation. Its refrigeration efficiency in medium-to-low temperature conditions significantly outperforms traditional refrigerants, effectively reducing operational energy consumption of refrigeration equipment. Additionally, it exhibits excellent compatibility with polyester-based refrigeration oils, making it suitable for most medium-to-low temperature refrigeration systems without requiring extensive retrofitting.

Primary application scenarios include commercial cold chain warehousing, supermarket refrigerated cabinets, food processing freezing equipment, pharmaceutical cold storage, and low-temperature logistics transportation within the medium-to-low temperature refrigeration sector. Regarding customer collaboration cases, we supplied R-507 refrigerant for a cold chain upgrade project at a major Shanghai supermarket chain. The supermarket operated 500 refrigerated cabinets and 10 large cold storage units, previously using R502 refrigerant, which exhibited low refrigeration efficiency and high energy consumption. After switching to R-507 refrigerant, the refrigeration efficiency of the cabinets and storage units increased by 20%, while energy consumption decreased by 15%. This resulted in annual electricity cost savings exceeding 800,000 yuan, while also ensuring food freshness and safety. Additionally, we supplied R-507 refrigerant for a pharmaceutical company's vaccine cold storage project. This facility requires stable maintenance of a -25°C storage temperature. After implementing the R-507 refrigeration system, temperature fluctuations were controlled within ±0.5°C, meeting the stringent requirements for vaccine storage.

The advantages of R-507 refrigerant are as follows: First, it offers excellent refrigeration performance with high capacity and efficiency in medium-to-low temperature conditions, meeting the demands of various medium-to-low temperature refrigeration equipment. Second, it operates stably; its azeotropic properties result in minimal temperature slip, enabling precise temperature control and ensuring consistent refrigeration performance. Third, it offers excellent replacement capability as a perfect substitute for R502 refrigerant, directly compatible with existing R502 systems without requiring major modifications, thereby reducing upgrade costs for enterprises. Fourth, it boasts high safety as a non-flammable, non-toxic gas with stable chemical properties, ensuring safe and reliable operation without corrosion or toxicity risks.
