What color is refrigerant oil?

Refrigerant or PAG (synthetic compressor) oil is clear, he explains. Over time, it picks up moisture and turns acidic, eating away at the condenser, thermal expansion valve, evaporator, fittings, compressor and other metal components. Gradually, the oil turns yellow and darkens as it picks up particles and sludge.

What is the difference between PAG oil and POE oil?

Polyolester (POE) – the primarily synthetic oil for refrigeration systems using HFC refrigerants. It is also suitable for refrigeration systems using CFC, HCFC refrigerants and being evaluated in CO2 systems. ​​Polyalkylene​ Glycol (PAG) – a synthetic oil primarily used in R-134a automotive air conditioning systems.

Is POE oil compatible with mineral 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. as HFC-134a does not mix well with mineral oil.

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.

Can I use Poe instead of PAG?

Registered. PAG is not compatible with POE and mineral oil is not compatibile with R134A period. you need to use one and ONLY one type of oil in the system, either all PAG or all POE. generally, PAG is recommended for automotive but technically POE is a better oil and can be used if you want.

What does an AC refrigerant leak look like?

If your evaporator coil has tiny holes through which it is leaking refrigerant, you can detect them by a collection of tiny bubbles near the leak. These are also known as “champagne leaks” due to the presence of tiny bubbles.

What does Freon look like when it leaks?

Ice Build-Up on the Copper Lines or Evaporator Coil

A tell-tale sign of a refrigerant leak is ice build-up on the copper lines or evaporator coils. When your system lacks the necessary refrigerant to cool your home, the copper lines or evaporator coils can absorb as much heat.

Is refrigerant oil toxic?

Freon is a tasteless, mostly odorless gas. When it is deeply inhaled, it can cut off vital oxygen to your cells and lungs. Limited exposure — for example, a spill on your skin or breathing near an open container — is only mildly harmful. However, you should try to avoid all contact with these types of chemicals.

Is POE oil hygroscopic?

One major concern with POE oils is that they are hygroscopic. If they remain in contact with air, they have the ability to absorb its moisture. For a technician, this means that when a repair requires opening a system, it should only be left exposed to the atmosphere for as long as necessary to complete the repair.

At what temperature does POE oil breakdown?

Mineral oil will start to decompose at approximately 350ºF (400ºF for POE oil). As temperatures increase above this threshold, the oil starts to polymerize.
