2019年2月25日 · R-404A provided an immediate replacement product for both R-12, R-22 and R-502. This allowed the world to stop using Ozone depleting refrigerants. R-404A operated at comparable physical and thermodynamic properties that R-502 did which made transitioning to new systems or retrofitting older systems a much easier task.

Freon™ 404A (R-404A) is a blended hydrofluorocarbon (HFC) refrigerant comprised of R-125, R-134a, and R-143a. It was designed to replace R-502 and R-22 used in commercial refrigerator equipment for low and medium temperature ranges. Its properties make it ideal for use in display cases, refrigerated vehicles, ice makers, and other applications.

Should compressor oil be changed at the same time as refrigerant? It’s important to ensure that system oil is compatible for each component and every alternative option. Danfoss POE oil must be used with any Danfoss commercial compressor, including subsequent future models.

R-404A is a ternary mixture consisting of R-125, R-143a and R-134a. Their thermodynamic characteristics constitute as ideal replacement for R-502 for refrigeration sector in new facilities at low and medium temperatures. R-404A is characterized by a remarkable chemical stability and low glide temperature 0.7 ° C. Its classification is A1 group L1.

reonTM 404A (R-404A) offers the best overall properties when compared with R-502. Capacity and efficiency values should be equivalent to R-502, and compressor discharge temperatures may be up to 9 °C (14 °F) lower than.

Genetron® 404A (HFC-404A) is a non-ozone depleting compound designed to serve as a long-term alternative to Genetron® 502 (CFC-502) and Genetron® 22 (HCFC-22) in low- and medium-temperature commercial refrigeration applications.

There are significant differences between R-502, R-404A, and R-452A, which must be considered when handling, processing, applying, or retrofitting with these refrigerants. These guidelines are offered to help understand the differences. NOTE: R-404A is a near azeotrope and therefore needs to be charged in the liquid phase.

Forane® 404A refrigerant (R-404A) is a non-ozone depleting, near azeotropic blend of HFC refriger-ants R-125, R-143a, and R-134a. R-404A is formulated to closely match the properties of R-502, making it useful for a variety of medium and low temperature refrigeration applications.

R404A is a HFC blend that is widely used in low and medium temperature refrigeration applications, such as those used in commercial refrigeration. Whilst it has become the widely accepted alternative to CFC R502, R404A is coming under greater scrutiny due to its high Global Warming Potential.

The only lubricant suitable to use with R404A is polyolester oil (POE). Toxicity and storage: Toxicity of R-404A is very low even with long exposure time. AEL (Allowable Exposure Limit) is 1000 ppm (8-hour TWA). R-404A containers should be stored in a cool and ventilated area away from heat sources.
