Hydraulic Oil Coolers (Air-Oil Exchangers)
Hydraulic Oil Coolers, by EMMEGI, are used for the cooling of hydraulic circuits using ambient air conveyed over the radiator by a fan driven by an electric or hydraulic motor as a coolant.
The radiator core, in high-tensile aluminum alloy, is obtained by means of a vacuum brazing production process. The configuration of the tubes increases the turbulence of the fluid and, consequently, also the Hydraulic Oil Cooler heat exchange capacity. Furthermore, the presence of special turbulators on the finned surfaces of the cooling element improves the overall transmission coefficient. The result is a small-sized, light, and robust technologically advanced Hydraulic Oil Cooler.

Hydraulic Oil Coolers – FAQs
What is the best way to cool hydraulic oil?
The best way to cool hydraulic oil is by using hydraulic oil coolers, which effectively manage the temperature of the oil to prevent overheating and maintain system efficiency. Air-cooled or water-cooled oil coolers are commonly used depending on the specific needs and environmental conditions.
How does an hydraulic oil cooler work?
An hydraulic oil cooler works by transferring the heat from the hydraulic oil to a cooling medium, typically air or water. The oil circulates through the cooler where it is exposed to cooling fins or plates that dissipate the heat, thus lowering the temperature of the oil before it returns to the hydraulic system.
Are oil coolers worth it?
What are the different types of hydraulic oil coolers?
The different types of hydraulic oil coolers include air-cooled oil coolers, water-cooled oil coolers, and specialized coolers like brazed plate heat exchangers and combination coolers. Each type has its own advantages and is suited to particular industrial environments and cooling requirements.
How do I choose a hydraulic oil cooler?
To choose a hydraulic oil cooler, consider factors such as the type of hydraulic system, the ambient environment, cooling capacity required, and space constraints. It’s also important to assess the cooler’s compatibility with the hydraulic fluid used and the expected thermal load of the system.
What is the best type of oil cooler?
The best type of oil cooler depends on your specific requirements. Air-cooled oil coolers are versatile and suitable for environments lacking water resources, making them easier to maintain. Water-cooled oil coolers provide more efficient cooling but require a reliable water source and are best for applications with high heat loads.
