The viscosity of lubricants is also the measure of the lubricant's resistance to flow. Low viscosity lubricants are thin and flow easily like water. High viscosity lubricants are more like molasses, they are thick and have high resistance to flow. The viscosity of an engine oil is significant for three primary reasons. The compressors are charged with ester oil (POE) with a viscosity of 15 cSt. Alternative oils that can be used in a service situation are: Emkarate RL15H, manufactured by Uniqema
In mechanical refrigeration system, moving parts should be lubricated with oil for a long life and effective work.There are different refrigerant and oil, including mineral oil, polyol ester-based oils, alky! benzene, and polvalkylene glycol (PAG), the type of oil used should correspond to the type of refrigerant used.
conventional oil, and are a step up from an ordinary Group II base oil. In fact, most of today’s “conventional” 5W-20 and 5W-30 multi-viscosity oils are actually blends and contain a certain amount of Group III oil. As for the various additives in oil, many are necessary to achieve the minimum API requirements for multi-viscosity rating, wear Viscosity: consistency or thickness of a fluid expressed in terms of resistance to flow.

Retroﬁts of R-22 systems with non-ozone-depleting alter-native refrigerants such as R-404A or R-407C will require multiple oil changes and possibly more extensive modiﬁca-tions to the existing equipment. For some systems, the cost
The oil dripped slowly onto an inclined steel panel held at 282°C, spread out as it flowed down, dripped off the panel and was pumped back up to repeat the process. This is a dynamic coking test as opposed to a static test, so the oil flow washes over the panel and has the opportunity to dissolve deposits and their precursors if it is able to. This oil is popular in Asian dishes, and has a medium smoke-point, which makes it best for light sautéing, sauces and low-heat baking, according to Popeck. “Sesame oil is rich in mono- and ... The main task of the refrigeration oil is to ensure the sufficient lubrication of all moving driving gear parts of the refrigeration compressor. In addition, depending on the design of the compressor, heat must be dissipated from the hot components and the sealing of the compression chamber and, if necessary, also the valves, must be guaranteed.

Lauric acid (also called Dodecanoic acid) is the main acid in coconut oil (45 - 50 percent) and palm kernel oil (45 - 55 percent). Nutmeg butter is rich in myristic acid (also called Tetradecanoic acid ) which constitutes 60-75 percent of the fatty-acid content. Oil Pressure Control Check List Here is a general listing of possible causes of oil failure trips, followed by a description of each: • Low compressor oil level. • The system refrigerant piping is not designed or sized properly. • The system has not been properly adjusted and balanced. • Lack of proper “winter-charge” of refrigerant. Transfer POE oil to system by pressurizing recovery tank with dry nitrogen, and "pushing" POE into evacuated system Do final overnight evacuation of system, while baking filter dryer with heat lamp Final note: Always install new filter dryer as last item when building or reworking system, and never leave it exposed to air unnecessarily. provided that the kinematic viscosities at two temperatures are known the charts have been simplified into an equation see next slide ideal for use with our 7827 viscometers as we can measure on line kinematic viscosity astm d341 the kinematic viscosity temperature charts covered by this standard are a convenient means to ascertain the, history of the astm viscosity temperature charts x1 7 5 a ... refrigerant and oil, the new oil must be miscible with the old oil in the system. POE has good miscibility with mineral oils, whereas PAG oils have poor miscibility. POE oils is also more hydrolytic stable than PAG oils. Depending on the type of compressor different kinds of bearings and bearing arrangements are chosen.
lubricants including polyol ester (POE), polyalkylglycol (BAG) & others. The ability to use traditional lubricants both reduces cost and avoids the use of hygroscopic synthetic oils which can absorb moisture during maintenance.

Synthetic Motor Oil Many new Toyota models are certified for a new, zero-weight synthetic lubrication standard, or 0W-20. This lower viscosity oil pumps better when cold, yet provides uniform lubrication, reduced friction and better overall efficiency than conventional engine oil. Improves fuel economy. Improved thermal stability.
Oil Mixing When POE oils first gained common use it was widely rumored that mixing POE and mineral oil would result in "sludge". This has been proven to be a myth, and to some extent manufacturers of retrofit, refrigerants have been suggesting adding small amounts of POE to mineral oil to help carry it through the system.

Polyol ester lubricants meet these needs, and the EMKARATE RL line is the preferred industry choice. Working in close collaboration with compressor and system manufacturers, these OEM- approved POE lubricants cover a wide viscosity range from 7 cSt (35-40 SUS) to 220 cSt (1100 SUS) to suit most applications.
You are correct POE oil is best if there is a chance that residual mineral oil from R12 is present. POE is both miscible (mixable) with mineral oil and a superior lubricant to PAG. That said people do make PAG work with R12 conversions. Toyota uses Dens Oil 8 which is equivalent to PAG 46 I believe but most every shop just uses PAG 100.
Compressor Oil or to pretest any stock Oil before it is to be added to a System. The traditional pH test in a bottle cannot measure the full range of Oil contaminants. A pH test will only work after a System has been exposed to long term acid production. Therefore, when the acid content of the Oil is ruled by the pH method, it is already a foregone
Nov 07, 2018 · In systems where oil return could be an area of potential concern, e.g. containing a liquid receiver, flooded evaporators or long & complex pipelines, the replacement of up to 25% of the oil charge with a POE is recommended starting with an initial 10% followed by increments of 5% until the oil level stabilizes & returns to normal. Obviously with the correct oil type and viscosity (i.e. if the compressor needs PAG 46 oil, PAG 150, PAO 68 or POE 55 oils won't do any good to it). Use a polyol ester (POE) oil. Check with Climalife regarding the viscosity of the oil selected for your application, and the miscibility with the fluid under consideration. PRECAUTIONS OF USE Refer to the Safety Data Sheet*. REGULATION The use and implementation of R-410A are governed by EU Regulation n° 517/2014. Oil Mixing When POE oils first gained common use it was widely rumored that mixing POE and mineral oil would result in "sludge". This has been proven to be a myth, and to some extent manufacturers of retrofit, refrigerants have been suggesting adding small amounts of POE to mineral oil to help carry it through the system.

In complex processes such as the compounding of high viscous masses, the quality of the end product is the key factor. From metering, through raw materials feeding, conveying, melting, dispersing, homogenizing, devolatilizing, pressure build-up, filtering and pelletizing, every process step has to be precisely adapted to suit the application. This oil withstands the heavy loads found in gear boxes. Viscosity is the thickness of an oil. The higher the grade, the thicker the oil, and the less it flows. Mineral oil is derived from petroleum and is usually more economical than synthetic oil. Synthetic oil lasts longer than mineral oil and withstands a wider range of temperatures.
