What color is POE oil?

Castrol POE is one of the ones that can go from almost colorless, to dark yellow, to dark amber / orange as the antioxidant falls apart.

Is polyol ester oil?

One such chemical that can be encountered in air conditioning and refrigeration condensate drains is Polyol Ester oil, commonly called POE oil, which is a type of Synthetic oil used to lubricate refrigeration compressors.

Is ester oil and POE oil the same?

POE/ESTER OIL Because mineral oil and PAG oil cannot be mixed, another A/C compressor oil was needed to bridge the gap for system conversions. The transitional solution was polyol ester oil (“ester” oil or POE). Ester oil is often called “retrofit oil” because it mixes with both R-12 and R-134a.

Does ester oil mix with mineral oil?

Ester oil mixes with and is compatible with mineral oil. Ester oil can be used with R12 and R134a refrigerants. Ester oil is not as harsh to o-rings, seals and paints as PAG oils. This is the oil that comes in or is supplied with the compressors that come from Everco, Murray, and Four Seasons.

What can ester based oils be mixed with?

Natural ester fluids are miscible with conventional mineral oil fluids. Natural ester fluids can be mixed with conventional mineral oil dielectric where the mineral oil concentrations are up to 8% without significant degradation of their most signifi- cant dielectric and fire point properties.

What is Poe a C oil?

Polyolester oil (POE oil) is a type of synthetic oil used in refrigeration compressors that is compatible with the refrigerants R-134a, R-410A and R-12. HFC-134a with POE oil as the lubricant is a replacement for CFC-12 with mineral oil as the lubricant.

What does POE oil smell like?

What type of oil is in the compressor, POE or MO? I wouldn’t describe it as sweet, but POE that has been exposed to moisture can emit a strong odor which I would say is closer to dirty socks.

What is ester oil used for?

Ester oil is synthetic base oil that has been chemically synthesized. Typically ester oils are used in passenger car air-conditioning compressors, refrigerators and other industrial applications. Esters are one of the classes of synthetics that have been used in Mobil 1™ oils as well.

Can you mix mineral oil and Poe?

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. HFC refrigerants can only use POE oil.

What is ester based oil?

Can I use ester oil instead of PAG oil?

Ester molecules are very stable and have excellent performance characteristics in both high and low temperature environments. Ester oil is typically used in systems that have been retrofitted to R-134a, and it comes in only one viscosity so it does not contain the viscosity numbers associated with PAG oils.

Can ester oil be mixed?

Additionally, there are other oils, like esters, that can be mixed with this group. A lot of esters are used as plasticizers in industry. We use esters in our oils to give the oil solvency. There also base stocks, like alkylated naphthalenes, which are a little bit new but can be mixed as well.
