Maintenance and Replacement Suggestions for Atlas Copco Oil Coolers
Regular Cleaning: For air-cooled coolers, clean the dust and oil stains on the fins regularly. For water-cooled ones, check if the water channels are blocked or clogged to ensure the cooling effect.
Leak Check: During daily inspections, observe if there are oil stains on the surface and interface of the cooler. If leakage is detected, replace the sealing parts or the entire kit promptly.
Replacement Timing: When the cooler shows severe corrosion, large-scale damage to the fins, or internal blockage causing abnormal oil temperature rise (above the specified upper limit of the unit), it is recommended to replace the entire kit. Preferentially use Atlas Copco original accessories to ensure compatibility with the unit and cooling performance.
The reliable operation of this kit directly affects the energy consumption, stability, and service life of the oil-free air compressor, and is an important guarantee for maintaining the efficient operation of the unit.
The main composition and function of Atlas Copco's oil cooler kit
Cooler body: Usually adopts an efficient finned tube structure, through forced air cooling or water cooling methods, to discharge the heat generated by the compressor during operation, maintaining the optimal working temperature of the lubricating oil and the compression system (generally controlled at 80-95℃), avoiding deterioration of oil quality, decrease in unit efficiency or damage to components due to overheating.
Companion accessories: Include seals (such as O-rings, gaskets), fixing brackets, connection pipes or joints, to ensure the precise connection of the cooler with the oil circuit system of the unit, preventing oil leakage and ensuring installation stability. Some kits may also include temperature sensors or bypass valves, for monitoring oil temperature and protecting the system in extreme cases.
Adaptation characteristics
Customized for the oil flow rate, pressure parameters and installation space of the ZA, ZR5-6 series oil-free air compressors, ensuring the matching of heat dissipation efficiency with the unit's power, avoiding the impact on equipment performance due to insufficient cooling capacity or incompatible dimensions.
Manufactured using oil-resistant and high-temperature-resistant materials (such as copper, aluminum alloy or stainless steel), adapting to the physical and chemical properties of the compressor's lubricating oil, prolonging the service life of components.
