IS 407C still available?

IS 407C still available?

A number of common refrigerants, including R134a, R410A and R407C, will be banned from use in new chillers in the USA from January 1, 2024.

IS 407C as good as R-22?

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. If a system has R22 in it already you cannot use a replacement refrigerant to simply add to the R22.

Can you put 407C in a R-22 unit?

R407C can be used to COMPLETELY replace R-22 refrigerant in new or existing R-22 residential and commercial air conditioning systems as well as non-flooded evaporator chillers. Cannot be added to R-22 unless fully evacuated and recharged with 407C.

Can you mix R407C with R410A?

Will it work, yes.

Can you mix R22 and R407C?

4. 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.

Do you charge 407C as a liquid or vapor?

liquid
R-407C should always be charged as a liquid. Due to its zeotropic nature, it will fractionate if charged as a vapor, causing poor system performance — and, possibly, system failure. Additionally, the refrigerant supply in the cylinder may become out of spec if discharged as a vapor.

What happens if you mix R22 and 407C?

If you mix R407C with R22 inside your system the molecule of the HFC (R407C) gas will not link with the oil and in just few months of operation you will have a “sludge” like lubricant formation inside the circuit.

Can you top off 407C refrigerant?

Yes. It is a blend of HFC-32, HFC-125, and HFC-134a (23/25/52 wt%). Freon™ 407C can be topped off after a leak, multiple times, with minimal impact on system performance.

Do you charge 407C as gas or liquid?

What are normal pressures for 407C?

Recovery of R-407C requires a cylinder with a service pressure of 300 psig minimum. National Refrigerants, Inc.
