Air blast oil coolers are a type of heat exchanger used to cool hydraulic oils, lubricating oils, or other fluids by using air to remove the heat from the oil. These coolers are designed to handle high heat loads and are commonly used in industries where machinery or engines generate a lot of heat during operation, such as in heavy equipment, automotive engines, or industrial machinery.

Chillmax Technologies is the best air blast oil cooler manufactures in India, special purpose cooling equipment manufacturers in India and supplies a wide range of air blast oil coolers to various industrial sectors to facilitate cooling of oils such as lubricating oil hydraulic oil and cooking oil.. We manufacture air blast oil coolers with high quality raw materials and space to provide state of the art infrastructure facilities and machineries to our clients. Mainly air blast oil coolers are employed to increase the efficiency of machineries by controlling liquid temperatures and we are proud to say that we are one of the largest air blast oil cooler manufacturers in India serving major cities.

With years of experience in manufacturing of oil coolers, we have emerged to be one among the major manufacturers of air blast oil coolers in the country. We build our oil cooling systems to be economical and efficient where atmospheric air is sucked into cool the oils in the closed loop. Made with best quality aluminium fins and copper tubes, our coolers are best suited for hydraulic power packs that are connected to return back to the system with easy to work and hassle-free work performance. We supply air blast oil coolers in AC, DC and hydraulic drives with the capability to cool duties ranging 1 kW to 100kW which are best suited to reduce the temperature of fluids in machine tools.

Here’s how they work:

• The oil flows through a series of tubes or channels inside the cooler.
• As the oil moves through, air is blown across the surface of the cooler to absorb the heat.
• The warm air carries the heat away, leaving the oil cooler and at a lower temperature, which is then recirculated in the system.

Some of the key benefits of air blast oil coolers are:

1. Compact and Efficient: They are relatively compact and effective at heat dissipation, making them suitable for space-constrained environments.
2. No Need for Water: Unlike water-cooled systems, air blast coolers don’t require an additional water source.
3. Low Maintenance: They are generally easy to maintain and don't require complex plumbing or cooling towers.

Features:

1. Airflow System: Air blast coolers are equipped with powerful fans or blowers that force air through the cooler, ensuring that the heat transfer process is efficient. These fans can be electric or powered by the equipment itself.

2. Cooling Capacity: The capacity of an air blast oil cooler is often rated in terms of how much heat it can remove, typically measured in kilowatts (kW) or British Thermal Units (BTUs). This capacity will depend on factors like the design of the cooler, the flow rate of oil, and the temperature of the air.

3. Materials: The core of these coolers is often made of high-conductivity metals like aluminum or copper for better heat exchange. These materials help in maximizing the cooling performance while keeping weight down. In industrial settings, corrosion-resistant materials might be used for enhanced durability.

4. Temperature Control: Some advanced models come with temperature sensors that can monitor and adjust the cooling process, providing more precise temperature control of the fluid being cooled.

Applications:

• Hydraulic Systems: Air blast oil coolers are often used in hydraulic systems to maintain the oil temperature within optimal ranges, ensuring efficient operation of hydraulic machinery such as presses, lifts, and heavy-duty construction equipment.

• Industrial Equipment: Machines with high mechanical loads, like pumps, compressors, and CNC machines, generate heat. Air blast coolers help keep the operating temperatures in check, thus improving performance and extending the lifespan of the equipment.

• Automotive & Engine Cooling: In engines (especially those in heavy-duty vehicles, trucks, or machinery), maintaining the correct oil temperature is critical to prevent overheating and damage to engine components. Air blast coolers help manage the oil temperature effectively.

• Power Generation: Power plants, particularly those using turbines or engines, rely on efficient oil cooling for the lubricating systems. Air blast coolers help in regulating the oil temperature in turbines and generators.

• Marine Applications: In marine vessels, the engines and hydraulic systems often require oil cooling to prevent overheating in harsh operating conditions. The air blast oil coolers are used on these ships or rigs.

Advantages:

1. No Water Dependency: Air blast coolers don’t rely on an external water source, unlike water-cooled coolers, which makes them ideal for places where water supply might be limited or costly.

2. Lower Risk of Corrosion: Water-cooled systems are prone to corrosion and scaling, especially in harsh environments. Since air blast coolers don't use water, they are less susceptible to these issues.

3. Cost-Effective: Air blast oil coolers typically have a lower upfront cost compared to water-based systems, especially in regions where access to water is difficult or expensive.

4. Flexibility: These coolers are highly customizable to meet specific cooling needs. Whether you’re cooling a small machine or a large industrial system, air blast coolers come in different sizes and configurations to match various applications.

5. Durability: Designed to handle high temperatures and tough environments, air blast coolers can withstand heavy-duty use, making them perfect for industrial machinery, vehicles, and engines.

6. Energy Efficiency: Since they rely on air as the cooling medium, they don’t consume additional energy like a water pump might in a traditional water-based cooling system.

Considerations:

• Space and Airflow: Proper airflow is crucial. These coolers require adequate space around them for air to flow freely. If the system is placed in a location with limited ventilation, it can affect the cooler’s efficiency.

• Ambient Temperature: The efficiency of air blast coolers can be influenced by the surrounding ambient temperature. In extremely hot environments, they may need to be larger or use more powerful fans to provide the necessary cooling.

• Maintenance: While they’re generally low maintenance, regular cleaning of the cooler’s air intake and fins is required to prevent dust and debris from clogging the system, which could hinder airflow and reduce efficiency.

Types:

• Fixed Speed: The fan operates at a constant speed, regardless of the cooling needs. These are typically less expensive but might not be as energy-efficient as variable-speed systems.

• Variable Speed: The fan speed adjusts based on the oil temperature, providing more precise control over the cooling process and potentially improving energy efficiency.

• Combined Air-Water Systems: Some air blast coolers are combined with water-cooling systems for situations where you need extra cooling power in extreme conditions. The air handles the primary cooling, while water is used for additional heat dissipation.
