EATON Airflex Water-Cooled Third Generation Brake E-CLCL-CC003-E December 2013

Water Cooled Third Generation Brake Description Eaton’s water-cooled tensioning brakes achieve industryleading, high-energy absorbing, dynamic braking. The revolutionary third generation brakes incorporate an improved internal design and increased water flow allowing for improved fluid dynamics with better energy dissipation characteristics. The third generation water cooled brake is available with Eaton’s dual piston design (WCBD3) and with Eaton’s air and water cooled combination style brake (WCSB3). Features and Benefits • Highest HP in class - 1000 HP per disc offers faster tripping time...
