• Specification

• Function 

1.Control Hydraulic Oil Temperature

During excavation, the hydraulic system generates substantial heat. This radiator uses a bar-and-plate core design to maximize surface area, allowing high-temperature oil to release heat to the air as it passes through the fins and tubes.
Cooling: In hot or high-load conditions, it reduces oil temperature to prevent degradation and maintain proper viscosity for efficient operation.
Warming: In cold starts, it helps the oil reach operating temperature quickly, improving responsiveness.

2.Protect Hydraulic Components

Oil degradation: Formation of sludge and varnish, reducing lubrication and potentially clogging filters and valves.
Component damage: Seals, gaskets, and metal parts may expand or degrade, leading to leaks and premature failure.
Performance decline: Lowered pressure and flow rates, resulting in slower cycle times and reduced productivity.
The radiator ensures the oil remains within the recommended temperature range (usually 50–80°C), protecting the system from these issues.
