New Product Compressor Oil POE68 200L Lubricant Oil For Refrigerant System

refrigerating machine oil

The refrigerant oil should have a good low pour point, a good compatibility with the refrigerant and thermal and oxidation stability. The largest consumption is mineral oil type, generally using naphthenic base oil, it has a low pour point, no wax, low temperature fluidity

Some types of refrigerant oil require synthetic hydrocarbon oil as the base oil

Application field

(1) Lubricate the friction surface so that the friction surface is completely separated by the oil film, thus reducing the friction work, friction heat and wear

(2) The flow of refrigerant oil takes away the friction heat, so that the temperature of the friction parts is kept within the allowed range

(3) Fill the sealing part with oil to ensure the sealing performance and prevent the leakage of refrigerant

(4) The movement of oil takes away the grinding debris generated by metal friction, and plays the role of cleaning the friction surface

(5) Provide hydraulic power for unloading mechanism

FAQ

Q1 How to choose the right lubricant?
*According to the requirements of the owner's manual, select according to the AP and SAE levels.
*Compared with mineral oil, synthetic oil has more stable performance, can extend oil change period, and save fuel. It should be used as much as possible.
*The SN level is higher than the SM level and has better wear resistance. It should be used as much as possible.

Q2 The quality of the oil is good or bad, Look at the API indicators. What is the classification of the API indicators?
There are two main types of engines, namely gasoline engines and diesel engines. The API also regulates engine oil into two categories. The gasoline engine oil API quality level starts with S, while the diesel engine starts with C. The quality level is in alphabetical order, and the higher the letter, the higher the level.
Gasoline engine oil API level: SA, SB, SC, SD, SE, SF, SG, SHSJ, SL, SM, SN
Diesel engine oil API level: CA, CB, CC, CD, CE, CF, CF-4, CG-4, CH-4, CI-4

Q3 How to choose the right viscosity?
*The new car uses a lower viscosity, such as: 5W-30
*The old car uses high viscosity oil, such as: 15W-50
*When the temperature in the north is low, choose low viscosity, such as: 5W-30
*Generally, you can choose moderate viscosity, such as: 5W-40

Q4 My car doesn't drive in very harsh environments. Do you need such a good lubricant?
Most vehicles do not drive in harsh environments, but the use of high quality lubricants has become a consensus:
As new technologies continue to be applied to engines, the engine's operating conditions are becoming more stringent and thedemand for lubricants is increasing. High-quality grades of lubricants reduce engine wear, piston and piston ring deposits,providing full lubrication to the engine and extending engine life.

Q5 Do I need to flush the engine before replacing this product or other Oumali engine oil?
Not necessary at all. There is no need to make any special preparations when changing from conventional oil to this
