Refrigerants are the lifeblood of cooling systems, and understanding their chemical composition and properties is fundamental to appreciating their function. R404A, a widely adopted mixed refrigerant gas, is a prime example of sophisticated chemical engineering for refrigeration and air conditioning applications. NINGBO INNO PHARMCHEM CO.,LTD. is a key player in providing this essential compound.

R404A is classified as a hydrofluorocarbon (HFC) blend, specifically designed to replace older refrigerants like R502 and R22. Its chemical composition typically includes three main components: difluoroethane (R125), trifluoroethane (R143a), and tetrafluoroethane (R134a). The precise blend ratio is engineered to achieve a specific set of thermodynamic properties, including a low boiling point (-46.5 °C), a critical temperature of 72.1 °C, and a critical pressure of 3.74 MPa. These characteristics make it highly effective for low and medium-temperature refrigeration cycles.

The high purity of R404A refrigerant gas is critical for its performance. As supplied by manufacturers like NINGBO INNO PHARMCHEM CO.,LTD., it typically boasts a purity of 99.9%. This ensures minimal presence of moisture (≤10 PPm), acidity (≤1 PPm), and vapor residue (≤100 PPm), all of which are detrimental to compressor lubrication and system integrity. The colorless and odorless nature of the gas also contributes to its ease of use and safety.

As a retrofitted refrigerant for R502, R404A offers a significant advantage in terms of environmental impact, as it has zero ozone depletion potential (ODP). While it does have a global warming potential (GWP), its efficiency in many applications can contribute to overall energy savings. Businesses looking to buy R404A refrigerant gas are investing in a product that balances performance with contemporary environmental considerations.
