Oil cooling is indispensable in a variety of applications:

• machine tools: to control the temperature of the hydraulic oil or spindle oil, preventing deformation and resulting in better surface finish and accuracy of the finished product
• chip-removing machines: Cooling of the cutting oil improves the life of the machine tool and allows a better surface finish of the final product.

Thanks to their configurability and high thermodynamic performance, ORA oil chillers can perfectly meet the requirements of these industrial applications.
