Copeland Bulletin SB2013CC-1 R1 was released to confirm that POE oil is an approved lubricant in all R-22 Copeland Scroll Air Conditioning (AC) and Heat Pump (HP) residential applications.

Is R-22 compatible with POE oil?

There are no true drop-in replacements for R-22. POE (polyolester oil) – a synthetic lubricant used with HFCs and required for all R-22 replacements.

What oil is compatible with R-22?

Refrigerant R-22 has been successfully used with mineral oil in residential air-conditioning and heat pump systems (AC/HP).

Which oil can be used in an R134a system?

Answer and Explanation: The lubricant which is used with the refrigerant R-134a is Polyolester oil (POE oil). Polyester oil is a type of synthetic oil. R134a does not mix well with mineral oils.

What refrigerants are compatible with POE 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.

Short 22 - Mineral & POE Oil

What refrigerants are compatible with R-22?

An R-22 Refrigerant Replacement for Direct Expansion Refrigeration. Freon™ MO29 (R-422D) refrigerant is a low-toxicity, non-ozone depleting hydrofluorocarbon (HFC) replacement for R-22.

Can you use 407C with POE oil?

POE lubricant is recommended for use with Freon™ 407C.

Is 134a a POE oil?

When performing an A/C repair, it is imperative to use the correct refrigerant oil. Compatible with both R1234yf and R134a systems, the TEMP Select® POE oil is formulated for its dielectric properties and low flammability to ensure every job is completed according to OEM specifications.

Is there a substitute for R134a refrigerant?

A High-Performing Alternative to R-134a

Opteon™ XL10 (R-1234yf) refrigerant is a non-ozone depleting (ODP) hydrofluoroolefin (HFO) option that meets the industry's growing demands for sustainable, safe, and effective solutions.

What type of oil is specified for R1234yf systems?

When undertaking lubricant selection for HFO 1234yf oil compatibility systems there remains a market acceptance that specialty synthetic 'double end-capped' polyalkylene glycols ('PAGs') are the preferred OEM choice.

Can I put R-134a in a R-22 system?

No, the compressor will fail. These two refrigerants have very different properties. One of R22 and R134a is high pressure and the other is low pressure. They don't mix chemically and don't have the same boiling point, leading to inefficiencies and eventual compressor failure.

Does 407C use the same oil as R-22?

Replacing R-22 with Freon™ 407C in these systems requires switching to polyolester (POE) oil. For a no-oil change R-22 replacement, see Freon™ MO99.

Does 404A use POE oil?

An Emerson approved Polyol Ester (POE) lubricant should be used with R-404A/R-507. For a complete list of all lubricants approved by Emerson refer to Form 93-11. These lubricants are available from all Authorized Copeland™ Wholesalers. The use of other POE lubricants may void the compressor warranty.

Can you use POE oil instead of PAG oil?

POE oil has greater insulating properties than PAG and can help to protect the insulation on the windings, preventing electrical leakage. Using the wrong oil in hybrid vehicles may allow current to short circuit back through the A/C compressor, creating a shock hazard.

What can I use instead of R-22 refrigerant?

Freon MO99 is the gold standard for R-22 alternatives and was developed by the same scientists who engineered Freon R-22. The benefits of Freon MO99 include: Capacity — The ability of Freon MO99 to heat or cool a given space is closer to Freon R-22 than any other refrigerant on the market.

Which of the following refrigerants would be used with POE oil?

POE (Polyolester) oil is recommended for use with refrigerants like R-1234yf, R-1234ze, and R-1234zd in air conditioning and refrigeration systems. 2. POE oil is compatible with these specific refrigerants and helps ensure proper lubrication and performance of the system.

What would happen if I put R134a in a R-1234yf system?

Still, the answer is an emphatic, “No.” Not only would a retrofit of this type negate the environmental benefits of R-1234yf, but it would also be a violation of Federal Law under Section 203 of the Clean Air Act: “tampering” with a vehicle's emissions control device.

What is the drop-in replacement for 134a?

There are three refrigerants that can be used to replace R-134a: R-1234yf, R-152a, and R-744.

Why is R134a being phased out?

Why Is R-134A Being Phased Out? When Is the Phaseout Expected to Conclude? Like a lot of '90s relics, R-134A has not aged well. It was known then that 1,1,1,2-tetrafluoroethane could potentially contribute to acid rain and that its ozone layer depletion potential was high.

Is R-22 OK with POE oil?

Can I use my new Copeland scroll compressor filled with 3MA POE oil in an R22 application? The refrigerant R-22 is compatible with POE oils.

What is the biggest concern with POE oil?

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.

Which oil can be used in an R134a system?

Polyelkylene Glycol (PAG) oil is a synthetic oil used by OEMs in their R-134a systems.

What happens if you mix R-22 and 407C?

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.

What refrigerants use POE oil?

Polyolester oil (POE oil) is a type of wax-free synthetic oils used in refrigeration compressors that is compatible with the refrigerants R-134a, R-410A, and R-12.

What oil does R-22 use?

As many of you have already noticed, all Copeland, R22 compressors are now being shipped with POE oil instead of the standard mineral oil.
