Hydraulic Oil Cooling Systems for Industrial Machinery
Every hydraulic system generates heat during operation and if left uncontrolled, that heat becomes the leading cause of equipment failure, fluid degradation, and costly downtime. Overheating alone accounts for nearly 20% of all hydraulic system failures, making hydraulic oil temperature control one of the most critical aspects of system design and long-term maintenance.
A reliable hydraulic oil cooling system ensures your machinery runs at safe, stable temperatures, reducing energy losses and protecting seals and internal components from premature wear.

Oil-Air Coolers as the name suggests are cooling the fluid – usually oil or water-glycol using atmospheric air. These coolers primarily consist of a fan which is externally powered and a heat exchange cooling element which is constructed of finned tubes.
The Hot fluid flows through the cooling element, and the fan draws external air and drives it through the cooling element resulting in a temperature difference, hence heat exchange takes place.
The continuous process of circulation results in transferring this heat from the
fluid to air thereby relieving the excessive heat that builds up in a hydraulic
system.
To size, a cooler for an application requires various parameters to be considered.
Primary, is the heat load. The greater the heat load, the cooler needs to be sized
proportionally to ensure the heat load is taken care of. Other major consideration
includes the Hydraulic oil flow required, desired oil temperature, oil viscosity,
and more.
To ensure system performance and reliability, it's best to install an oil air cooler for all applications, with minimum impact on the existing layout.
A wide range of coolers with various options and designs are available, This includes a cooler with axial and radial fan designs. AC supply, DC supply, and hydraulic motors, to ensure the versatility of the product in catering to a variety of applications needs and ambient conditions.
We offer a wide range of Oil-Air coolers in different sizes and series with a wide range of accessories to enable to allow flexible adaptation to various application requirements.

The brazed plate heat exchanger consists of several corrosion-resistant material corrugated plates, vacuum-brazed with copper or nickel depending on the application. This creates flowing channels between plates through which a hot medium and a cold medium (typically water) are circulated, thus achieving the purpose of Heat Exchange

The performance of an existing installed Oil Air cooler can be improved by using various types of available accessories, with these, it is possible to increase control, efficiency & security of the cooler and hence the complete hydraulic system
These accessories are available in different sizes and ranges to meet the most common requirements. The accessory depending on your application can be sourced out and integrated with your new oil air cooler or can be added later also thru the necessary mounting kit.
Spares and Accessories that we offer
- Cooling Element Matrix
- Cooler fan
- Thermostat Kit – Adjustable type
- Thermostat Kit – Fixed type
- Bypass Valve – Pressure controlled
- Bypass Valve – Temperature controlled
- Dust Guard
Depending on the installed cooler series and type code, we offer a cooling element matrix and cooler fan depending on your requirements.
Thermostat Kit is an Electrical Switch mounted on one of the cooling element-free ports which operates the Fan motor. In the Adjustable type, the switch opens or closes the circuit at the selected temperature, while in the fixed type it closes the cooler circuit at the set fixed temperature
The bypass valve allows the oil to bypass the cooler matrix when a certain pressure (pressure-controlled valve) / temperature (temperature-controlled valve) is exceeded, thereby protecting the cooling element from bursting
Dust guards are external grills to protect the cooler matrix in particular, plus components and systems from tough conditions.

FAQ'S
A hydraulic oil cooling system regulates the temperature of hydraulic fluid by dissipating excess heat generated during operation. Without proper cooling, overheating can cause fluid degradation, seal damage, component wear, and ultimately system failure making it an essential part of any hydraulic setup.
The three most widely used types are Oil-Air Coolers, Brazed Plate Heat Exchangers, and Pump-Transfer Cooler Filtration Units. Each type suits different applications depending on heat load, available space, coolant medium, and operating environment.
If your hydraulic system runs continuously under heavy load, operates in high ambient temperatures, or frequently experiences overheating warnings, a dedicated cooling system is strongly recommended. Rising oil temperatures above safe limits are a clear sign that cooling is required.
Hydraulic oil ideally operates between 40°C and 60°C. Temperatures consistently above 80°C can accelerate oil oxidation, reduce viscosity, damage seals, and shorten the lifespan of hydraulic components significantly.
An oil-air cooler uses ambient air to cool hydraulic fluid through a fan and finned-tube element ideal for mobile and outdoor equipment. A brazed plate heat exchanger uses water or coolant as the cooling medium, offering higher capacity and efficiency for large industrial systems.
Selecting the right cooler depends on four key parameters — heat load (kW), oil flow rate (lpm), desired operating temperature, and oil viscosity. Our technical team analyses these factors and recommends the most suitable cooling solution for your specific application.
Yes. Most oil cooling systems, including oil-air coolers and plate heat exchangers, are designed for easy integration into existing hydraulic circuits with minimal modifications. Mounting kits and custom configurations are also available for retrofitting into older systems.
Regular maintenance is recommended every 6 to 12 months depending on operating conditions. This includes inspecting and cleaning the cooling element, checking fan performance, verifying thermostat operation, and replacing any worn accessories such as bypass valves or dust guards.
