For professionals in the HVACR sector, selecting the correct refrigerant is paramount to system efficiency, longevity, and compliance. This article focuses on R507A, a widely utilized refrigerant, and examines its critical specifications. Understanding these details helps in making informed decisions when you plan to buy R507A refrigerant gas or integrate it into new systems.

R507A, scientifically known as HFC-507, is an azeotropic blend composed of two primary hydrofluorocarbons: R-125 (pentafluoroethane) and R-143a (1,1,1-trifluoroethane). Its chemical formula reflects this composition, CHF2CF3 and CH3CF3. A key characteristic is its physical appearance: it is colorless and clear, with a faint, ether-like odor. This odorless nature is advantageous in applications where smell might be a concern.

One of the most significant properties of R507A is its high purity, typically exceeding 99.5%, with many suppliers offering grades up to 99.93%. This high level of purity directly impacts system reliability. Impurities can lead to increased system wear, reduced efficiency, and potential component failure. Therefore, when looking at R507A purity 99.93%, it signifies a premium product suitable for the most demanding refrigeration applications.

Delving into its thermodynamic properties, R507A has a molecular weight of 98.9 g/mol. Its boiling point at atmospheric pressure is approximately -46.7°C (-52.1°F). This low boiling point is fundamental to its function as a refrigerant, allowing it to absorb heat effectively. The latent heat of vaporization is also a crucial factor for cooling capacity calculations.

From an environmental perspective, R507A has an Ozone Depletion Potential (ODP) of 0, meaning it does not contribute to the depletion of the ozone layer. However, its Global Warming Potential (GWP) is substantial, cited at 3985. This high GWP is a primary driver for the global phase-down of HFCs. Despite this, R507A continues to be used in existing systems and in new equipment where its performance is deemed essential and lower-GWP alternatives are not yet suitable.

The CAS number for R507A is 354-33-6, a standard identifier for chemical substances. Its applications are diverse, ranging from residential air conditioners to complex industrial and commercial refrigeration systems. The R507A for air conditioner systems provides efficient cooling, while its suitability for low and medium-temperature refrigeration makes it a versatile choice. Professionals often seek R507A refrigerant gas for its balance of properties, even as they navigate evolving environmental regulations.

When considering the R507A refrigerant gas price, it's important to note that this can fluctuate based on global supply chains, regulatory changes, and demand. NINGBO INNO PHARMCHEM CO.,LTD. and other suppliers offer R507A, providing essential documentation like Safety Data Sheets (SDS) and quality certifications to ensure transparency and compliance.

In summary, the detailed specifications of R507A highlight why it has been a popular refrigerant. Its high purity, effective thermodynamic properties, and zero ODP make it a capable refrigerant, though its high GWP necessitates careful consideration of its long-term use and potential replacements. Understanding these technical details is vital for any professional involved in the selection and use of refrigerants.
