DC Compressor is a professional manufacturer and supplier of Atlas Copco Air Compressor Cooler in China, we have our own factory and focus on the supply of core components for gas compression equipment. We offer a full range of original Atlas Copco coolers, covering air-cooled, water-cooled and other types, suitable for multi-industry scenarios.
In the process of air compressor operation, air compression will produce a lot of heat, if not released in time, it will lead to a series of problems such as high temperature of equipment, damage of parts, deterioration of lubricating oil, etc. As the core component of the cooling system, Air Compressor Cooler carries the key mission of "cooling guard", and its performance directly determines the operating stability, service life and operating efficiency of the air compressor.
The core function of Air Compressor Cooler is not only to cool the high temperature compressed air (usually from 100-140℃ to 40-50℃) and lubricating oil generated in the compression process to safe operating temperature, to avoid high temperature damage to the main engine and various parts, but also to condense the water vapor in the compressed air into liquid water through cooling, and then discharge it through the drainer to achieve dehydration and drying effect, reducing the risk of internal corrosion and failure of the system. At the same time, reducing the exhaust temperature can also reduce the load of the aftertreatment equipment, improve the operating efficiency of the entire compressed air system, achieve the purpose of energy saving and consumption reduction, and effectively prevent the oxidation and deterioration of lubricating oil caused by high temperature, aging of seals and damage to rubber parts, and comprehensively protect the safety of the system.
DC Compressor has been deeply involved in the field of gas compression equipment for many years, deeply aware of the importance of coolers to equipment operation, always insist on supplying original Atlas Copco coolers, and build a solid heat dissipation defense line for the stable operation of customer equipment from the source. Our products cover steel, chemical, automotive, medical, new energy and other industries, and have provided thousands of enterprises with suitable cooler solutions.
Atlas Copco air compressor coolers are divided into multiple types according to different installation positions and cooling media, which can accurately adapt to the needs of different models of air compressors and application scenarios, providing customers with diversified choices.
Classified according to installation position, mainly includes three core products: one is oil cooler, specially used for cooling circulating lubricating oil, to avoid high oil temperature affecting lubrication effect and oil life, usually installed after the oil-gas separation system, is the key heat dissipation component of oil injection screw air compressor; The second is aftercooler, the core function is to cool compressed air, installed after the air compressor exhaust port, belongs to the standard configuration of air compressor, almost all air compressors need to be equipped; The third is the intercooler, which is specially designed for multi-stage air compressors. It is used to cool the compressed air between all levels of compression. It can effectively reduce the power consumption of the next stage of compression and improve the compression efficiency of the whole machine. It is widely used in high pressure and ultra-high pressure air compressor equipment.
According to the classification of cooling medium, it can be divided into three categories: air cooling, water cooling and mixed cooling. Among them, air-cooled type (TD series) adopts aluminum fin heat dissipation structure, relying on fan forced ventilation cooling, no external water source, flexible and convenient installation, especially suitable for water shortage areas, mobile equipment and small and medium-sized fixed units; water-cooled type (HD series) adopts stainless steel shell structure, cold water and compressed air flow in reverse, high heat exchange efficiency and low energy consumption, suitable for water abundant areas, large units and high temperature environment; The hybrid cooling type combines the advantages of air cooling and water cooling. The core area adopts water cooling to ensure the cooling effect, and the edge area adopts air cooling to adapt to the environment. It is specially designed for extreme working conditions or equipment requiring extremely high cooling accuracy.
DC Compressor has a professional selection team, which can accurately recommend the most suitable cooler type for customers according to the model, power, exhaust volume, working pressure and operating environment of the customer air compressor (such as water source, ambient temperature, etc.) to ensure that the cooling effect matches the equipment operation requirements perfectly.
What is the difference between the structure and working principle of Air Compressor Cooler?
Atlas Copco air compressor cooler structure design and working principle will be different according to the different cooling type, but the core is around the "efficient heat transfer" development, all parts cooperate to achieve stable cooling effect.
From the structural point of view, air-cooled cooler is mainly composed of aluminum heat exchange fins, heat exchange tubes, axial flow fans, fan motors, protective covers, drains and brackets. Aluminum fins and heat exchange tubes adopt integrated design to greatly improve heat conduction efficiency, fan and motor cooperate to achieve forced ventilation, and protective cover ensures safe operation of equipment. The water-cooled cooler is composed of stainless steel heat exchange tube bundle, shell, end cover, inlet and outlet interface, sewage outlet and drain. Stainless steel material ensures corrosion resistance and service life of the equipment. The end cover is designed for subsequent disassembly and maintenance. In addition, all types of coolers are equipped with temperature sensors, differential pressure indicators, safety valve interfaces and automatic drainage systems for operational status monitoring and safety protection.
In terms of working principle, the operation logic of the air-cooled cooler is simple and efficient: high temperature fluid (air or lubricating oil) flows through the aluminum heat exchange tube, and the forced air flow is generated after the fan is started, and the heat is rapidly dissipated into the atmosphere through the fins, thereby achieving cooling. The fan adopts automatic temperature control design, which can automatically adjust the speed according to the fluid temperature, and realize energy-saving operation while ensuring the cooling effect. Water-cooled coolers use counter-current heat exchange technology, high temperature fluid flows inside the heat exchange tube, cooling water flows in reverse outside the tube, this counter-current design can maximize heat exchange efficiency, heat is transferred to the cooling water through the tube wall, and then continuously carried away by the cooling water. The cooler built-in moisture separator will collect condensed liquid water, and finally drain through the automatic drainer to complete the dual tasks of cooling and dehydration.
DC Compressor's technical team has a deep understanding of the structure and working principle of various coolers, and can provide customers with detailed product descriptions and operation guidance to help customers quickly master the equipment operation logic and accurately determine the equipment operation status.
Atlas Copco has built a variety of high-performance cooler series products with century-old technology accumulation. Each series model adapts to different scenarios, with multiple advantages such as high efficiency, durability and intelligence, becoming the first choice for global industrial customers.
The mainstream standard cooler series covers four core types: TD series air-cooled aftercooler, aluminum integrated cooling element, with low wind resistance design, fan protection level up to IP55, suitable for GA/GX/GZ series small and medium-sized air compressor, widely used in small and medium-sized manufacturing, hardware processing and other industries; HD series water-cooled aftercooler adopts stainless steel tube bundle structure, low water consumption and built-in moisture separator, suitable for GA/GA+ series large air compressor, which is the core choice of large industrial enterprises such as steel and chemical industry;OC series oil cooler adopts efficient heat transfer design, oil temperature control accuracy can reach ±2℃, which can adapt to high pressure conditions and cover all series of oil injection screw air compressors; IC series intercooler, designed for multistage compression, pressure capacity ≥25bar, single-stage cooling range ≥50℃, is an essential part of high pressure, ultra-high pressure air compressor.

DC Compressor, as Atlas Copco's authorized partner supplier, has a stable supply capacity of a full range of cooler products. It can quickly match the corresponding cooler model according to customer equipment models and needs to ensure the perfect fit between products and equipment.
Cooler long-term in high temperature, high load operating environment, or due to improper maintenance, may appear a series of failures. Timely troubleshooting and scientific solution measures can effectively avoid fault expansion and reduce equipment shutdown losses. DC Compressor combines years of service experience, summarizes common faults and corresponding solutions of coolers, and provides practical guidance for customers.
If the exhaust temperature is too high to cause equipment tripping, four major causes should be investigated first: air-cooled fin blockage, water-cooled pipe scaling, fan failure, and insufficient cooling water flow. The corresponding solutions are: blowing dust from the inner side of the fin with compressed air; removing scale in the pipeline by chemical cleaning; checking whether the fan motor and belt are damaged and repairing or replacing them in time; adjusting the water valve to increase the cooling water flow.
If cooler leakage is found, it is mostly caused by aging seals, corrosion of heat exchange tubes or loose end cap bolts. At this time, it is necessary to replace the aging seal ring; repair or replace the corroded heat exchange tube; tighten the end cover bolts evenly to avoid leakage caused by uneven stress.
When condensate drainage is not smooth, there is a high probability that the drainer is blocked, the moisture separator is fouled, or the system pressure difference is insufficient. The solution is to clean or replace the drain; disassemble and clean the scale in the moisture separator; check the system pressure to ensure that the pressure differential meets the drainage requirements.
If there is too much pressure loss in the equipment, it is necessary to focus on three aspects: scaling or carbon deposition inside the cooler, inlet and outlet valves are not fully opened, and pipes are blocked. Internal impurities can be removed by chemical cleaning; valve status checked to ensure complete opening; clogged pipes unblocked to restore normal circulation.
Regular and scientific maintenance is the core of prolonging the service life of Atlas Copco air compressor coolers and ensuring their stable operation. Combined with product characteristics and industry experience, DC Compressor combs detailed maintenance points and processes for customers to help them establish a perfect maintenance system.
In the maintenance cycle, the following standards should be strictly observed: surface cleaning of air-cooled cooler fins, once every 2000 hours or 3 months; internal cleaning of water-cooled cooler bundles, once every 8000 hours or 1 year; inspection of drains for all types of coolers, once a month; replacement of water-cooled cooler end cap seals, once every 2 years; fan motors and belts for air-cooled coolers, once every 4000 hours.
Different types of cooler maintenance procedures have their own emphasis. Air-cooled cooler cleaning should strictly follow the process of "shutdown pressure relief-purge cleaning-oil stain treatment-component inspection": first stop the equipment operation, disconnect the power supply, release the system pressure; use 0.4-0.6MPa compressed air to purge dust from the inner side of the fin; if the fin has heavy oil stain, clean it with neutral detergent, then rinse it with clean water and dry it; finally check whether the fan blade and protective cover are intact to ensure no damage.
Cleaning of water-cooled cooler shall be carried out according to "closing valve and removing cover-chemical cleaning-clean water flushing-replacing seal-pressure test": close cooling water inlet and outlet valve, remove end cover; circulate special pipe cleaning agent to remove scale and oil in pipe; thoroughly flush the inside of tube bundle with clean water; replace new seal and reassemble, and finally carry out pressure test (test pressure is 1.2 times of working pressure) to ensure no leakage.
Drainage system maintenance can not be ignored: regularly check the working state of the automatic drainer to ensure smooth drainage; clean the drainer filter element and regularly replace the aging parts; in winter, antifreezing measures should be taken to add antifreeze to the water cooling system to avoid freezing cracks in the pipeline.
DC Compressor regularly reminds customers to carry out maintenance work, and provides detailed maintenance instruction manuals and professional training for customers to help customers master maintenance skills and reduce equipment failure rates.
Correct selection and standard installation are prerequisites for optimal performance of Atlas Copco air compressor coolers. DC Compressor combines a large number of practical cases to provide customers with targeted selection and installation suggestions to help customers avoid common problems.
Three core principles should be followed in the selection: one is to match the equipment parameters, select the corresponding cooler according to the core parameters such as power, exhaust volume and working pressure of the air compressor to ensure that the cooling capacity matches the equipment requirements; the other is to adapt to the environmental conditions. If the ambient temperature exceeds 35℃, it is necessary to select products with cooling capacity increased by 10-15%, so as to avoid high temperature environment affecting the cooling effect; Third, considering the water source and water quality, the water-cooled system should be selected according to the water source situation. In the area with hard water quality, it is recommended to use it with water softener to reduce the risk of pipeline scaling.
Four points should be paid attention to during installation: when installing air-cooled coolers, it is necessary to ensure that a space of ≥500mm is reserved around the equipment to ensure smooth ventilation and avoid heat dissipation due to poor ventilation; valves and pressure gauges should be installed at the inlet and outlet of water-cooled coolers to facilitate subsequent maintenance and pressure monitoring; disassembly space should be reserved during installation to facilitate subsequent cleaning, maintenance and replacement of parts; The cooler exhaust port must be installed downward to ensure smooth discharge of condensed water and avoid water accumulation affecting the cooling effect and equipment life.
In addition, during the selection and installation process, if the customer has any questions, DC Compressor's professional technical team can provide one-on-one guidance, combining with the customer's actual production scenario, equipment model and other details, to give accurate selection scheme and installation drawings, to ensure that the cooler installation specification, stable operation.
