What is Qishanr Refrigeration Oil?

Qishanr and Qishanr QSL
Qishanr is the world's leading supplier of synthetic lubricants to the refrigeration and air conditioning industry. Qishanr QSL is an OEM approved synthetic refrigeration lubricant for appliance, large industrial systems, air conditioning (residential, commercial, or transport) and automotive or aftermarket applications.

Application of Qishanr QSL

The Qishanr QSL brand provides a complete range of viscosities coupled with quality, reliability and performance for original fill oils and retrofit aftermarket service oils. 

Qishanr QSL lubricants are designed for standard factory fill of air conditioning and industrial refrigeration equipment, as well as for OEM retrofitting operations. They provide improved properties over conventional mineral oils in all aspects, including flash and fire points and pour point.

Advantages of Qishanr QSL
Qishanr refrigeration oils have the following characteristics which assure maximum trouble-free service life:
1.Chemical stability: To resist interaction with the refrigerant or metal parts in the system.

2.Thermal stability: To eliminate excessive carbon deposits at compressor hotspots such as valves or discharge ports.

3.Low wax content: To prevent separation of flocculent wax from the oil-refrigeration mixture at the low temperature points in the system.

4.Low pour point: To prevent separated oil from congealing in refrigerant lines. 

5.High dielectric strength: To ensure good insulating properties. In hermetic units, the oil-refrigerant mixture serves as an insulator between the motor and the compressor body.

6.Proper viscosity: To ensure high film strength at elevated operating temperatures and good fluidity under the coldest operating temperatures even when diluted with refrigerant. 

7.No contamination: To prevent scarring of bearing surfaces, plugging of lines or oil ports and general deterioration.

Highly stable,essentially wax free, thus providingw excellent low temperature properties and assuring long trouble-free life. 
Application: Residential refrigeration and air conditioning systems.
