Frequently Asked Questions

What is the function of an oil cooler?

An oil cooler regulates engine or hydraulic oil temperature by dissipating excess heat generated during operation. It circulates hot oil through a core exposed to airflow or coolant, preventing oil breakdown, reducing viscosity loss, and protecting critical components like bearings, pistons, and hydraulic pumps from thermal damage and premature wear.
