FAQs

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.

RS44B is compatible both with the traditional mineral & alkylbenzene oils, and also the polyol ester lubricants so that there is no need to change the existing lubricant in the system when retrofitting to R22.

RS-44b is the lowest GWP HFC R22 replacement on the market at 1664 TAR and is Zero Ozone Depleting. Inadvertently mixing RS-44b with R22 is not harmful to the system. This has been verified in Europe, where RS-44b has been on the market for 15 years.

Freon MO99 is the gold standard for R-22 alternatives and was developed by the same scientists who engineered Freon R-22. The benefits of Freon MO99 include: Capacity — The ability of Freon MO99 to heat or cool a given space is closer to Freon R-22 than any other refrigerant on the market.

MO99 (R-438R) by Freon offers the closest performance match to R-22. RS-44 (R-424A) is a non-flammable mixture of HFC 134a, HFC 125, iso-pentane, butane and isobutene.

Mixing refrigerants is not recommended. R-22 replacements should not be used to top off R-22 systems. R-22 should be recovered using appropriate equipment and managed according to U.S. EPA guidelines specified in Section 608 of the U.S. Clean Air Act.

An R-22 Refrigerant Replacement for Direct Expansion Refrigeration. Freon™ MO29 (R-422D) refrigerant is a low-toxicity, non-ozone depleting hydrofluorocarbon (HFC) replacement for R-22.

R-407C should be used only in systems that currently use R-22. It should not be mixed with R-22 or any other refrigerant. 5. The capacity of the existing R-22 thermal expansion valve (TEV) will be approximately the same when using R-407C.

R-454B is a blend of R-32, a hydrofluorocarbon (HFC), and R-1234yf a hydrofluoroolefin (HFO). R-454B has a lower GWP than previous refrigerants, meaning it has a much lower climate impact.

You should not mix R-22 with any other refrigerant. However, some systems can support EITHER R-22 refrigerant OR R-410A refrigerant.

Is R44 a replacement for R-22? ›

RS-44 is suitable for use as a replacement for R-22 in new existing commercial and industrial air conditioning and refrigeration systems, and appliances.

Will R-454B work in existing R-410A systems? No. R-454B is NOT a drop-in replacement for R-410A.

R410A is the most common, but others include R134a, R407C and R407A. These refrigerants cool interior spaces just as effectively as R22 with no ozone depleting characteristics and relatively low Global Warming Potential (GWP).

Freon™ 407C has been a popular R-22 replacement because of its properties, which include: Similar cooling capacity, energy efficiency, and pressures as R-22 in systems. An ability to be topped off after a leak, multiple times, with minimal impact on system performance.

The information below will try to dispel some of these myths. Arkema recommends using Forane® 427A (R427A) - The EASY RETROFIT™ for your r-22 retrofit solution. When it comes to drop-ins, the truth is that there are none. The hope of “drop-in” refrigerants has become common over the years.

The best replacement for R-22 Freon is usually R-407c. It has a very low loss in capacity (0 – 5%) relative to R-22 and is less expensive than many other R-22 replacement refrigerants.

NU-22B® Replaces R-22, R-407C, R-422D and R-417A. NU-22B is the only R-22 replacement you need.

No. There is no such thing as a “drop in” replacement for R-22. Mixing refrigerants is not recommended. R-22 replacements should not be used to top off R-22 systems.
