Refrigeration oil serves as a hydraulic control, functional fluid and lubricating oil in refrigeration compressors under the influence of the refrigerant in Nairobi Kenya.

The lubrication of refrigeration compressors occupies a special position in lubrication technology. The longevity expected of refrigeration compressors is closely connected to the high quality which is required of refrigeration oils. The interaction with other substances which the refrigeration oil comes into contact with, and especially the extremely high and low temperatures, makes very specific demands on refrigeration oils.

The principal function of a compressor oil is to lubricate the pistons or rotors and to lubricate and seal the valves and, in some cases, the slip ring seals. Furthermore, the refrigeration oil must dissipate heat away from hot compressor components and assist in sealing the compression chambers and valves.

A refrigerating machine is a device that produces low temperatures by transferring heat. For example, room air conditioner and refrigerator. Most common refrigerating machines comprise of a compressor, a condenser, a thermal expansion valve, and an evaporator. A refrigerant circulates through the system, absorbing heat and then releasing heat repeatedly as it undergoes compression, condensation, expansion, and evaporation. This is the refrigeration cycle.
A compressor serves as the “heart” in this cycle, pumping the refrigerant through the system. A refrigeration oil is what lubricates the sliding parts inside the compressor.

Refrigeration oil is discharged from the compressor along with the refrigerant. The refrigeration oil needs to circulate through the refrigeration cycle and return to the compressor without building up and blocking the lines so that a suitable level of oil is maintained inside the compressor. For this to be possible, the refrigeration oil must be sufficiently soluble in the refrigerant (miscibility with refrigerant). Aside from lubricity, oil-refrigerant miscibility is one of the key performance requirements for a refrigeration oil.

Dandy Solutions LTD is the leading wholesale supplier of high quality refrigeration oils in Nairobi Kenya. We stock high quality refrigeration oils like Suniso 4GS among many others. SUNISO GS Oils are miscible well with HCFC and CFC refrigerants such as R-22, R-502 and R-12 while featuring excellent stability and giving long trouble-free service life in the refrigeration systems using above refrigerants. In addition, SUNISO GS Oils also perform excellently with natural refrigerants such as R-717, R-600a and R-290.

SUNISO GS Oils undergo refining from specially selected naphthenic crude oils by special method assuring excellent lubricity and other properties. Furthemore, SUNISO GS Oils have approval of all major air-conditioner, refrigerator, freezer, car air-conditioner manufacturers in the world.
