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.
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.
Refrigerant R-22 has been successfully used with mineral oil in residential air-conditioning and heat pump systems (AC/HP).
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.
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.
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.
POE lubricant is recommended for use with Freon™ 407C.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
There are three refrigerants that can be used to replace R-134a: R-1234yf, R-152a, and R-744.
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.
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.
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.
Polyelkylene Glycol (PAG) oil is a synthetic oil used by OEMs in their R-134a systems.
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.
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.
As many of you have already noticed, all Copeland, R22 compressors are now being shipped with POE oil instead of the standard mineral oil.
