Are MO99 pressures the same as R-22?

Are MO99 pressures the same as R-22?

The low side pressure with MO99 will be a couple of psi lower than R-22 while the high side (cond) will be slightly higher than R-22. The MO99 retrofit guide has a lot of useful information, including proper setting of superheat and subcool.

Can MO99 be mixed with R-22?

No. Freon™ MO99 should not be used to top off R-22 systems. Mixing refrigerants is not recommended. 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.

What happens if you mix Freons?

What Happens to Your AC System if You Mix Refrigerants? Mixed refrigerants can cause increased system pressures and temperatures changing them for the worse. This can result in ineffective compressor cooling and possible compressor damage, ineffective cooling, and metering device malfunction.

Is MO99 flammable?

This substance is not flammable in air at temperatures up to 100 deg. C (212 deg. F) at atmospheric pressure. However, mixtures of this substance with high concentrations of air at elevated pressure and/or temperature can become combustible in the presence of an ignition source.

Is MO99 same as R438A?

R438A (MO99) R438A (Freon™/Isceon MO99) is a HFC blend, used as a replacement for R22 in domestic, industrial and commercial air conditioning systems.

Is MO99 a blend?

R438A (Freon™/Isceon MO99) is a HFC blend, used as a replacement for R22 in domestic, industrial and commercial air conditioning systems. It is also a retrofit replacement for R22 in low and medium temperature refrigeration systems and DX chiller systems.

What should the high and low side pressures be for r12?

at 70 degrees the high side pressure should be around 170psi, and that generally puts the low side pressure between 35-40psi.

Can you mix refrigerants in a recovery tank?

Using certified recovery equipment, evacuate the refrigerant to 0 psig. Recover the refrigerant into a container used only for that type of refrigerant. Do not mix refrigerants. Store recovered refrigerant by refrigerant type (e.g., R-22, R-410A, etc.)
