What is an Industrial Oil Chiller？
An Industrial Oil Chiller is specifically designed to cool industrial oils such as hydraulic oil, lubricating oil, cutting oil or spindle oil. It controls the oil temperature within the set range, usually from 20 to 45°C through the refrigeration system.
Why Do You Need the Industrial Oil Chiller?
During industrial processing (such as milling, drilling or grinding), the oil serves to lubricate and reduce friction and it also takes away the heat from the processing area.
The excessively high oil temperature can lead to experiencing precision drift, component wear or oil quality deterioration and others. At this time, the oil chiller is necessary which can continuously absorb heat from the oil through a closed refrigeration cycle system and maintain the oil temperature at the set value for you.
Meanwhile, its built-in high-efficiency circulating pump can evenly deliver the cooling oil to each lubrication point or cutting area under constant pressure and flow rate. This ensures the heat is removed in a timely manner.
Furthermore, even after filtration, industrial oil still often contains fine impurities, but the cooler has an ability to handle slightly contaminated cooling media and be easy to clean.
In a word, the industrial oil chillerIt can keep your device always operating in an ideal state.

Working Principle of the Industrial Oil Chiller
Oil circuit cooling: The equipment introduces hot industrial oil into the heat exchanger (or evaporator) through a pump, allowing the oil to exchange heat with the low-temperature refrigerant.
- The refrigerant evaporates into gas after absorbing the heat from the oil.
- The cooled oil is output at a stable temperature and recycled back to the mechanical equipment to achieve continuous cooling.
Refrigeration cycle: The refrigerant absorbs heat from the oil and evaporates. It moves through a standard vapor compression refrigeration cycle.
- The refrigerant is compressed by the compressor into high-temperature and high-pressure gas. And then enters the condenser to release heat to the air or water and condense into high-pressure liquid.
- The high-pressure liquid refrigerant is throttling and depressurizing through the expansion valve to become a low-temperature and low-pressure state.And It then returns to the evaporator to absorb heat, completing the cycle.
Types of the Industrial Oil Chiller
According to Cooling Method
Air Cooled Industrial Oil Chiller
Air cooled oil chillers dissipate heat from the oil through forced air convection, without the need for external cooling towers or water sources. Due to its compact structure, short installation period and easy maintenance, it is very suitable for outdoor factories, water-scarce areas or temporary work sites.
In addition, the equipment can integrate with high-efficiency finned condensers and an intelligent air volume control system to ensure stable cooling performance for you even in high-temperature environments.
Water Cooled Industrial Oil Chiller
Water cooled industrial oil chillers efficiently exchange heat between cooling water and oil in shell and tube or plate heat exchangers. Its cooling efficiency is 3 to 5 times higher than that of air-cooled types, and it can maintain excellent performance in industrial settings with high loads and long-term continuous operation. Furthermore, water-cooling systems feature high-temperature resistance, oil resistance, and high heat exchange efficiency so that they are particularly suitable for high-temperature environments such as metallurgy, chemical engineering, and hydraulic stations.
You can choose a closed-loop water circulation system based on the on-site conditions to reduce the consumption of cooling water and extend the service life of the heat exchanger.
Evaporative Industrial Oil Chiller
The evaporative industrial oil chiller cools the oil though water evaporation absorbing heat. Combined with air condensation and wet curtain evaporation mechanisms, they only require a small amount of water replenishment to operate. Compared with traditional water-cooling systems, it can save about 80% of water and there is no need to install cooling towers.
The equipment is compactly designed for easy maintenance and is more suitable for integrated cooling in electrical cabinets, hydraulic stations and complete equipment systems.

If you need to optimize the cooling performance without replacing the entire system, the in-line type is your efficient and economical choice.
Parts of the Industrial Oil Chiller
Refrigeration system
The refrigeration system is composed of a compressor, evaporator, expansion valve and condenser, and is the core part of the oil chiller.
- Compressor: It provides the power for the refrigeration cycle and is commonly of scroll or screw structure. It operates stably and has high energy efficiency.
For working conditions with significant fluctuations in thermal load, you can choose a variable frequency Compressor which automatically adjusts the speed based on real-time oil temperature and load changes, achieving precise temperature control and energy-saving operation.
- Evaporator: In evaporator, the oil exchanges heat with the refrigerant. After absorbing heat, the refrigerant evaporates to cool the oil.
- Expansion valve: It precisely regulates the refrigerant flow rate to make the evaporation pressure and condensation pressure remain balanced. Some models use electronic expansion valves (EEV), which offer you higher flow response speed and control accuracy.
- Condenser: It discharges heat through air or cooling water to maintain efficient heat dissipation of the system.
The air-cooled type is suitable for factories with flexible installation and no cooling water conditions. While the water-cooled type has a higher heat exchange efficiency and is more suitable for continuous operation or high-load environments.
Oil circuit cooling system
- Circulating pump: The circulating pump is responsible for stably transporting the oil to each heat exchange part, ensuring the heat exchange efficiency of the entire system.
You can select different types of pumps according to the application pressure and flow requirements, such as gear pumps, centrifugal pumps or screw pumps.
- Liquid storage tank: The function of the liquid storage tank is to stabilize the oil pressure, store the oil and prevent the formation of bubbles in the system.
Some models are equipped with a low-temperature start-up heating function, which can preheat the oil in cold environments to prevent the oil temperature from being too low and causing difficulties in system start-up.
- Heat exchanger: It transfers heat between high-temperature industrial oil and coolant through media such as tube walls and plates.
Whether you choose shell and tube type, plate type, finned tube type or plate-fin type, all heat exchangers are treated with anti-fouling and anti-corrosion coatings, which can easily handle harsh working conditions.
Sensor
The system integrates temperature, pressure and flow sensors with a PID precision controller to reach real-time monitoring and automatic regulation of oil temperature.
Its oil temperature control accuracy can reach ± 0.2°C, and it is equipped with multiple overvoltage, overload and insufficient flow protections to ensure your safe operation.
Control unit
The control system has many functions including automatic start and stop, self-diagnosis of faults, and abnormal alarm, and it is equipped with overload protection and phase sequence protection to keep the long-term stable operation of the equipment.
Application of the Industrial Oil Chiller
Industrial oil coolers are widely used in process systems that require stable oil temperature and precise temperature control.
In CNC machining centers, the industrial oil chiller can be used to cool cutting oil, lubricating oil and spindle oil, which can effectively prevent spindle overheating and precision drift.
In the plastic molding industry, they usually adopt industrial oil coolers to cool mold oil and hydraulic oil to enhance molding efficiency and product consistency.
The hydraulic systems and lubrication circulation systems also need industrial oil chillers to reduce wear and extend equipment life by maintaining a constant oil temperature.
Consideration for the Industrial Oil Chiller
Cooling capacity
You should clear the cooling capacity to match the heat load of your equipment, capacity of the oil tank and the set temperature. Excessive cooling capacity will lead to frequent starts and stops of the system and low operational efficiency. If it is too low, it will cause the oil temperature to fail to meet the standard.
It is generally recommended to leave a 10-15% refrigeration redundancy when choosing to cope with environmental changes or fluctuations in operating conditions.
Oil pump pressure and flow rate
Please determine the specifications of the circulating pump depending on the flow rate and pressure drop of the equipment circuit. Insufficient oil flow will reduce heat exchange efficiency, while excessive flow will increase energy consumption and mechanical wear.
So it is recommended that you confirm the maximum pressure drop of the oil circuit during the selection stage to match the performance curve of the pump.
Operating environment
The performance of air cooled oil chillers is greatly influenced by ambient temperature and ventilation conditions. The typical maximum ambient temperature for non-outdoor coolers is 104°F, approximately 40°C.
If your machine running environment is dusty or hot, it is better to choose models with dust-proof filters and high-temperature resistant fans for you to work longer .
Convenience
It is also an important consideration that the oil cooler is easy to install and maintain. You should give priority to choosing a design with a quick-disassembly panel, a washable filter and a modular structure to reduce the cost of later maintenance.
