Composition of R404a Refrigerant Gas

Al Tawakkal Gen Trdg presents you with its exclusive range of R404a Refrigerant which is a perfect nearly Azeotropic Blend of the other three refrigerants- HFC-125, HFC-143a, and HFC-134a. This HFC blend was primarily designed to wipe out the other environment-destructing refrigerants; R22 and R502. The chemical composition of R404a comprises of 44% R-125, 52% R-143a, and 4% R134a. R404a was an ideal substitute for R22 and R502 as it was a retrofit solution for low and medium-temperature applications. Its excellent thermodynamic properties make it ideal for industrial and commercial refrigeration applications.  

Key Properties of R404a Gas

R404a is just like R22 but better with some additional properties and benefits.

Global Warming Potential:

R404a has a relatively low Global Warming Potential (GWP) of 3922 than R22 and R502. It is still discouraged to use in newer commercial and Industrial applications due to its GWP which is comparatively higher than modern refrigerants. GWP measures the potential for a Refrigerant to contribute to global warming over a specified time frame.

Ozone Depletion Potential:

One good key property of R404a is its non-ozone-depleting capability. Due to its chlorine-free nature, R404a plays no role in damaging the Ozone Layer making it safe for the environment. Its ODP is 0.

Temperature Glide:

R404a has marvelous chemical stability and a low temperature glide of 0.7 which makes the evaporating and condensing process of refrigerant happen at slightly different temperatures.

Boiling Point:

The Boiling Point of R404a Refrigerant gas makes it ideal for low-temperature applications. Its Boiling Point is -46.4°C (-51.5°F).

Benefits of R404a:

Environment-FriendlyR404a is highly environmentally friendly because of its 0 ODP. It doesn’t penetrate the ozone layer negatively.

Highly EfficientR404a is highly efficient when it comes to cooling in refrigeration applications. Its efficiency is not limited to only one or two applications but it provides unmatched cooling in every application; be it industrial applications or transportation refrigeration equipment.

Safe NatureThe refrigerant is classified as A1 from the ASHRAE safety class. It is non-flammable and non-toxic. It is safe to use, handle, and store. Steel Cylinders can also be utilized to store R404a in liquid form.

Cost-effectiveR404a is pretty cost-effective due to its wide availability. Unlike other refrigerants, you can find R404a easily in the market at comparatively low prices.

Smooth-TransitioningYou can rely on R404a to retrofit your older refrigeration systems which have been using R22 or R502 as their refrigerant. R404a can be easily transitioned from one system to another. However, Original Equipment Manufacturers (OEM) recommend the use of Polyester oil in the system while the system is working with R404a.

Applications:

R404a gas is used in multiple industries as a top choice of refrigerant. These industries are:

  • Commercial Refrigeration: Supermarkets, Grocery Stores, and Restaurants use R404a gas in walk-in coolers, freezers, and display cases.
  • Industrial Refrigeration: Here, R404a is used in cold storage, food processing, and other temperature-sensitive industries.
  • Transport Refrigeration: This industry uses R404a in refrigerated trucks and trailers to maintain cold chains for transporting perishable goods.
  • Air Conditioning: Some older refrigeration systems in commercial settings still use R404a as their refrigerant. However, newer models of refrigeration systems are moving towards more sustainable and environment-friendly options of refrigerants.

Safety Regulations:

According to EU F-gas Regulation 517/2014, manufacturing of new R404a plants will be prohibited from the beginning of 2020. This act bans every refrigerant which has a GWP of more than 2500.

However, R404a can still be used and recycled for maintenance purposes till the end of 2030. Plants are permitted to use R404a in their systems till it runs out of its lifespan.
