Is mo99 compatible with POE oil?
Also question is, can mo99 be mixed with r22?
There are "drop-in" R22 replacement in the market like R421a, R422B and MO99 (also MO29 for low-temp applications) but NONE of those can be mixed with R22.
Subsequently, question is, can I mix mineral oil and POE oil in a system? 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. HFC refrigerants can only use POE oil.
Regarding this, is mo99 a blend?
R438A, also known as ISCEON® MO99, is an HFC blend designed to be a "drop-in" replacement for R22 across a wide range of applications, including low, medium and high temperature refrigeration, and residential, commercial and industrial air conditioning.
What is the best replacement for r22 refrigerant?
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.
