Electro-hydraulic fan drive system One of Casappa’s aims is to develop targeted engineering solutions to improve machine performance. Designers of vehicle cooling systems require complete and flexible control systems. A cooling fan featuring a hydraulic drive offers significant advantages over traditional solutions with electric or belt drives. ADVANTAGES OF THE HYDRAULIC SYSTEM vs OTHER TECHNOLOGIES More powerful and more effective zz Reverse function available zz Energy savings and low noise level zz Flexibility in cooling system design zz Integrated controls zz Reduced overall dimensions...
