Is R407C compatible with mineral oil?
While polyol ester and polyvinyl ether oils are compatible with mineral oils, they should not be indiscriminately mixed with mineral oils in R407C refrigerant systems. This practice could result in the inability of the oil to return to the compressor and/or reduce heat transfer performance in the evaporator.
What oil is R407C compatible with?
In most instances, the lubricant in use with R-22 is a mineral oil or alkyl benzene. Polyol ester lubricants are recommended for use with Genetron® 407C by the equipment manufacturers.
What refrigerant is compatible with mineral oil?
Naphthene based mineral oils are suitable for refrigeration systems using CFC or HCFC refrigerants.
Does 407C require oil change?
407C REQUIRES AN OIL CHANGE TO POE OIL WHEN RETROFITTING A R22 SYSTEM! The addition of a hydrocarbon does not make the mineral oil and the refrigerant miscible but instead simply assists in the flow of the refrigerant within the system using the existing oil.
Will R407C be phased out?
Among the HFCs and HFC-blend refrigerants affected by the regulations are several that are familiar to facility managers: R-404A, R-134a, and R-410A and R-407C, used to replace R-22. Under the rules, new chillers would no longer be produced using these refrigerants after Jan. 1, 2024.
Can Poe and mineral oil be mixed?
Can I mix Polyol Ester (POE) and Mineral Oil (MO) together? When using CFC or HCHC refrigerants, POE and MO can be mixed. The exception is R12 that only uses MO or Alkyl Benzene Mineral Oil (ABMO) blend.
Can I use mineral oil with R134a?
R134a and mineral oils are not miscible. 3. Polyol ester oils and R134a are miscible. The miscibility of polyol ester (POE) oils and R134a is similar to that of current refrigerant oils and R22.
Can mineral oil and POE oil be mixed?
Re: Mixing POE and mineral oil Copeland states that POE oils can be mixed with mineral oil in some applications, including R-22.
Can I use 407C instead of 134a?
Re: Why can’t I top up my R407C air con with R134a Don’t worry, ofcourse you can use the same gas in all of them.
Is R134a compatible with mineral oil?
Is it OK to mix mineral oil with R407C?
compatible with mineral oils, they should not be indiscriminately mixed with mineral oils in R407C refrigerant systems. This practice could result in the inability of the oil to return to the compressor and/or reduce heat transfer performance in the evaporator. However, small amounts up to 5% of mineral oil are
What kind of lubricant to use on R-407C?
R-407C must be used with polyolester (POE) oil, since its solubility with mineral oil or alkylbenzene is limited. When retrofitting an old R-22 system, it will be necessary to flush out the mineral oil or alkylbenzene lubricant in the system and replace it with POE.
What happens when you mix R22 and R407c?
If your system is running on R22 most likely is using mineral oil to lubricate the compressor. 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 use mineral oil on a R-22 compressor?
Systems using R-407C may have a higher system pressure drop than with R-22. Check with the manu- facturer of any pressure regulators and pilot operated solenoid valves used in the system to be sure that they will operate properly. 12. Mineral oil lubricant, such as 3GS, cannot be used as the compressor lubricant.
