The refrigerant dissolved in the oil significantly reduces the viscosity, improving oil fluidity and minimising the negative influence on heat transfer in heat exchangers. Figure 2 shows the results of an autoclave test conducted on both POE and PVE oil mixtures with R-410A. If an oil is used that does not meet those requirements fairly closely, it might cause wear and friction issues. Although PAG oils have long been used as industrial lubricants, recent work has led to the development of PAG lubricants for use in equipment in the food processing industry. It is more hygroscopic that either POE or PVE oils, but it does not undergo hydrolysis in the presence of water. 134a, 32, 125, 152a and 143a with mineral oil, alkylbenzene, polyalkylene glycol and polyolester lubricants. Mineral – a by-product in the distillation of crude oil to produce gasoline. HVACR Tech Tip: When Should a Catch-All Filter-Drier be Changed?

Polyolester (POE) – the primarily synthetic oil for refrigeration systems using HFC refrigerants. Ester oil is often called “retrofit oil” because it mixes with both R-12 and R-134a. Remember, one of the leading causes of failures in automotive HVAC is … It is compatible with mineral oil and compared to mineral oil, it has improved refrigerant miscibility with R-22 at low-temperature conditions. So, along with R134a came a new oil: Polyalkylene Glycol—or PAG oil. New special PAG oils 46 YF and 100 YF, both suitable for refrigerants R1234yf or 134a Oil plays an important role in the air-conditioning system, no matter whether it's required when the compressor is replaced or for refilling during the air-conditioning service. Above this temperature, the wax will remain in solution. Hydrolysis – decomposition of a compound by reaction with water. The 2016 Pilot, Civic, and Fit EV are using R-1234yf. The advantage of ester oil is that it works with both R12 as well as R134a, so you can fill the system with it and then use either refrigerant. It is more hygroscopic that either POE or PVE oils, but it does not undergo hydrolysis in the presence of water. The older measure is Saybolt Universal Seconds (SUS); the newer is ISO viscosity grade number (ISO VG), a measure using centistokes. Compressor seizure. This is what happens when you hire the lowest bidder. These are oils based on polyol ester (POE) and polyalkylene glycol (PAG). Beitrag von Verdichter » 26.10.2011, 08:59 Hallo, was ist der genaue Unterscheid zwischen einem PAG und einem POE Öl? It is more hygroscopic than POE oil but less than PAG oil. von Verdichter » 26.10.2011, 12:34, Beitrag RENISO - Refrigeration oils based on Mineral Oil, PAG, PAO or POE. Leute, ihr strapaziert meine Nerven. Wie cool-mo sagt. Most all newer model cars use PAG as the lubricant in the A/C system. Fire Point – the lowest temperature at which the oil maintains combustion. Rolling element bearings are commonly used in compressors with small clearances and good linearity. It is more hygroscopic that either POE or PVE oils, but like PVE it does not undergo hydrolysis in the presence of water. PAG oder POE Öl. Techmid (ted mich.) Water is soluble in various degrees with the refrigerants and refrigeration oils. nonono! PAG Öle haben ein ausgezeichnetes Viskositäts-Temperatur-. It will not grant the old, original … von Verdichter » 26.10.2011, 08:59, Beitrag Using the kit, a sample of any refrigerant lubricant is sent to our laboratory. Keep POE oil in their original containers. Like PAG oil, PVE oil does not undergo hydrolysis in … Comparison of recovery of R134a Refrigerant gas out of PAO oil verses PAG oil. Initial FALEX testing showed di-capped PAG to have a 66% advantage in wear protection over POE and ordinary PAG oils. When looking at PAG oil you will notice various numbers such as PAG46 or PAG100. Heißt das diese Art von Öl sehr viel Wasser aufnimmt.Das könnte zur folge haben das das Öl Säure bildet und dein Verdichter oder genauer gesagt die Wicklung angegriffen wird und somit in die Knie geht. For comparison, an oil having a 150 SUS has an ISO viscosity grade of 32. The most hygroscopic refrigerant oils in descending order are: PAGs, PVEs, POEs, ABs, and mineral oils. Naphthene based mineral oils are suitable for refrigeration systems using CFC or HCFC refrigerants. A complete spectrographic analysis indicating the presence (in ppm) of up to 21 contaminants (including metals which indicate wear), plus a chemical analysis for acid, moisture content and oil viscosity is mailed to the submitter. The only way to remove the moisture is through the use of oversize filter-driers in the system. Some degree of miscibility is necessary between the oil and refrigerant so that the oil can return to the compressor during system operation. It has low viscosity PAG oil according to ISO 46. Polyalkylene Glycol (PAG) – a synthetic oil primarily used in automotive air conditioning systems. 1) No oil return and no lubrication of compressor inner parts. 4. PAG is actually an acronym for Polyalkylene Glycol, and it is a synthetic oil used in A/C systems to lubricate the compressor. Miscibility – the ability of the oil to mix with the refrigerant. 3. PAG oil with 100 weight percent oxypropylene groups are water insoluble; whereas those with 50 to 75 weight percent oxyethylene are water soluble at ambient temperatures. Eventually, this could cause the compressor to fail. Therefore, new lubricants with appropriate solubility/miscibility have been developed for systems with HFC and HFO refrigerants. The speed at which hydrolysis occurs is dependent on temperature and the acid content (acids can act as a catalyst). Keep the refrigeration system closed except when work is actually being performed on the equipment. POE oil is extremely hydroscopic, wants the water molecule back. Driers will not remove moisture from POE oil. Extra precautions to avoid exposure to moisture must be used with this oil. In the case of POE oil, it decomposes into partial esters, organic acid and alcohol in the presence of water. Moisture will rapidly cause POE oil to sludge Driers will remove moisture from mineral oil or PVE oil. ↳   Geschichte der Kälte- und Klimatechnik, ↳   Info-Austausch unter den Kältetechnikern, http://www.vde-verlag.de/buecher/leseprobe/lese3271.pdf. Note that there is another kind of oil called Polyol Ester Oil (POE). von cool-mo » 26.10.2011, 17:28, Beitrag One may consult oil approval listings such as the one published in Parker Sporlan Catalog G-1. Best practice is to ensure everything is set and ready before pulling the plugs on the compressor. This was the first replacement oil for mineral oils to be used with HFCs. HVACR Tech Tip: Prevent Destructive Superheat with TREV Liquid Injection, HVACR Tech Tip: Guide to Servicing Blended Refrigerants. What are the differences between POE and PAG Oil. These products are known as food-grade … Have a question about Parker products or services? 2. PAG öle sind sehr hykroskopisch. Oils can be applied by the player via Cassia, to Blighted maps, rings, amulets or blight unique items in order to add new modifiers or the effect of a passive skill: Blighted maps can have up to three anointments at a time. POE oil is extremely hydroscopic, wants the water molecule back. Minimize the time systems are … A low dielectric strength is indicative of moisture and/or contamination in the oil. CAUTION: PAG oils should NEVER be used in hybrid vehicles because it is electrically conductive. thank you very much for you web. ... also ist POE öl nicht oder weniger hygroskopisch? It is more hygroscopic than POE oil but less than PAG oil. Like blood in the human body, the oil fulfills vital tasks in the air-conditioning system. CO2, NH3, R22, R1234yf or R134a. This oil is suitable for A/C systems with R134a refrigerant. These numbers refer to the viscosity of the oil, similar to 10W30 oil. Also flushing seldom works and usually is a bad idea. Liquid GHS product identifier Other means of identification Product type Emergency telephone number Section 1. Moisture will rapidly cause POE oil to sludge Driers will remove moisture from mineral oil or PVE oil. 1) No oil return and no lubrication of compressor inner parts. PAG, PVE, and POE oils have polar structures which allow them to attract water molecules. Verdichter Beiträge: 13 Registriert: 22.07.2009, 11:23. Using PAG oil in hybrids can be hazardous to the vehicle, but it can also endanger the technician since there is an electrocution risk associated with using the wrong oil. Lastly, just like POE oils PAG oils are hygroscopic and can absorb moisture at a much faster rate than mineral oil. Viscosity, solubility (vapor pressure) and density data are reported for thirty-five working fluids, which are selected combinations of these refrigerants and companion lubricants. Minimize the time systems are … Although PAG oils have long been used as industrial lubricants, recent work has led to the development of PAG lubricants for use in equipment in the food processing industry. It is also suitable for refrigeration systems using CFC, HCFC refrigerants and being evaluated in CO2 systems. The transitional solution was polyol ester oil (“ester” oil or POE). Keep POE containers closed. With POE and PAG oils, evacuation will not remove the moisture. FUCHS RENISO refrigeration oils for virtually all refrigerants e.g. It is used in R-134a air conditioning systems to lubricate the compressor. However, because mineral oil and PAG oil are not to be mixed, another A/C compressor oil was needed to bridge the gap. Warum kann ich für einen elektrischen Verdichter kein PAG Öl verwenden? WAECO PAG ISO 46 - WAECO offers quality compressor oil to provide the best possible repair and maintenance results for car A/C systems. Ester molecules are very stable and have excellent performance … A high percentage of POE will reduce lubrication performance. ... also ist die elektrische Leitfähigkeit der einzigste Unterschied? Hygroscopicity – the ability of the oil to absorb moisture. However, because mineral oil and PAG oil are not to be mixed, another A/C compressor oil was needed to bridge the gap. von cool-mo » 01.11.2011, 22:25. ​​Polyalkylene​ Glycol (PAG) – a synthetic oil primarily used in R-134a automotive air conditioning systems. Article contributed by Chris Reeves, product manager, Contaminant Control Products, Sporlan Division of Parker Hannifin. Außerdem empfiehlt es sich, die Spezialöle des jeweiligen Kompressorherstellers zu verwenden, weil sie am besten auf die Fahrzeugklimaanlage abgestimmt sind. For hybrid-electric vehicles that use electrically driven compressors, polyol ester (POE) oil is not just recommended, its use is mandatory in many cases. you are taking your life in your hands. POE oil added to the refrigerant cycle. Please note that, in an effort to combat spam, comments with hyperlinks will not be published. von cool-mo » 26.10.2011, 12:00, Beitrag PAG oil with 100 weight percent oxypropylene groups are water insoluble; whereas those with 50 to 75 weight percent oxyethylene are water soluble at ambient temperatures. Previously, there were multiple PAG oils released to service GM vehicles using R-1234yf (using belt-driven A/C compressors), which required technicians to refer to the Service Information during every A/C service to ensure the correct PAG oil was used. POE/ESTER OIL. But one should confirm with the compressor manufacturer which oils are qualified for the particular compressor model, refrigerant, and application. A high percentage of POE will reduce lubrication performance. PAG oil, or Polyalkylene Glycol, is a fully synthetic hygroscopic oil specifically designed for automotive air conditioner compressors. Wie das Blut im menschlichen Körper, erfüllt das Öl in der Klimaanlage „lebenswichtige“ Aufgaben. Polyalphaolefin (PAO) oil can be used as a replacement for some PAG oils, and is sometimes preferred because it doesn’t absorb moisture from the air like other A/C compressor oils do. Thanks.... 07-26-2006, 07:03 AM #2. andL64. Esterification – the reverse of hydrolysis. Like PAG oil, Ester oil is a synthetic lubricant. The absence of these structures and materials results in a very non-polar base oil with a high viscosity index (of approximately 130), excellent low-temperature flow and pour-point characteristics, good oxidation stability and compatibility with mineral oils, paints and seals commonly found in lube oil system…
