    R453A (also known as RS-44b or RS-70)
     is a premium, non-flammable HFC-based drop-in refrigerant designed to replace R-22 in AC and refrigeration systems without requiring oil changes. It offers similar discharge pressures, lower operating temperatures, and better energy efficiency than R-22, with the lowest Global Warming Potential (GWP) among R-22 replacements (1664 TAR). 
    Key Features & Advantages 
    • Drop-in Replacement: No oil change is required; it is compatible with mineral (MO), alkylbenzene (AB), and polyolester (POE) oils.
    • Performance: Operates with similar cooling capacity and pressure to R-22.
    • System Protection: Contains small amounts of hydrocarbons to improve oil return and extend compressor life.
    • Safe: Non-flammable and zero ozone-depleting (ODP).
    • Applications: Suitable for residential, commercial, and industrial, including capillary tube and TXV systems. 
    Usage Notes 
    • Charging: Should be charged as a liquid to prevent fractionation.
    • Compatibility: Compatible with materials used with R-22.
    • Mixing: While not recommended, accidental mixing with R-22 does not cause system damage. 
    R453A is commonly available in various cylinder sizes (e.g., 24 lbs, 25 lbs) and is often sold as a "virgin" or "premium" product, such as the ComStar RS-44b.

    Can you mix R22 and RS 44?
    The Environmental Protection Agency (EPA) in the United States does not permit the mixing of different refrigerants. However, it is known from experience in Europe that the unintended mixing of RS-44b with R22 will not generate higher pressure readings, loss of efficiency or component damage.

    Is R-410A still being manufactured?
    Starting in January 2025, the production and import of R-410A for use in new HVAC systems will be prohibited. This means that all new commercial and industrial air conditioning units must utilize alternative refrigerants with lower environmental impact, such as A2L refrigerants like R-32 or R-454B.Jan 9, 2025
