What is 404A refrigerant gas?
R-404A is a pseudo-azeotropic mixed refrigerant composed of the three ingredients R-125, R-134a, and R-143a, and was developed as a substitute refrigerant for R-502 and R-22, used in commercial refrigerator equipment for low and medium temperature ranges.
What is 404A refrigerant used for?
R-404A is used across a variety of low and medium temperature applications including super market freezers/refrigerators, vending machines, ice machines, refrigerated transport, and industrial refrigerant systems.
Why is R404A being phased out?
R404a has the highest carbon dioxide rating of all refrigerants on the market, meaning the shift to a lower GWP refrigerant is imminent. A transfer to lower GWP products cannot wait until 2020 as it is necessary to move as soon as possible. This is because R404a will not be available to buy for virgin use.
Can you still buy 404A refrigerant?
The problem with this now is that as of January 1st, 2018 you can no longer purchase R-404A unless you are section 608 certified with the Environmental Protection Agency. Purchasing has been locked down to only certified technicians. This new rule is known as the ‘Refrigerant Sales Restriction’.
What replaces 404A refrigerant?
For cold rooms and other small to medium commercial refrigeration applications, R448A and R449A and R452A or R134a are excellent alternatives to R404A, with from 50 to 65% reduction in GWP. R513A, newer alternative, is also very appropriate in medium back pressure (MBP) applications.
Is R404A refrigerant still available?
Commonly-used high GWP refrigerants R404A and R507A are among a number of refrigerants to be banned in new retail food refrigeration from as early as January 1, 2021, with both also being banned in new cold storage warehouses from January 1, 2023.
Can I use R134a in a R404A system?
Re: Accidentally mixed R404A with R134a Vacuum is not necessary because R404a consists of R134a. It will never work and your TEV or capillary is not designed for this refrigerant. If you want to destroy your compressor, let it run this way.
What refrigerant is compatible with 404A?
R-449A is an HFO-based refrigerant blend designed to replace R-404A in stationary refrigeration applications. It combines excellent cooling performance and energy efficiencies with a low-GWP value of 1,397.
How much is a tank of 404A refrigerant?
$150 / 24lb cylinder = $6.25 per pound. There you have it folks, $6.25 for one pound of R-404A refrigerant.
Do you need a license to buy R404A refrigerant?
404A is an HFC refrigerant and does not harm the O-Zone layer so therefore you do not need to have any kind of certification to purchase.
