HPTO® – Wet Clutch

HPTO® Wet Disc Pack Clutches engage by “smoothly ramping” the clutch, much like using a viscous oil shear coupling to soft-start the driven load. Once the driven load is synchronized with the engine speed, the disc pack locks up at full torque to provide 100% of the engine’s horsepower to the driven load. The HPTO can start equipment with significant inertia or even under partially jammed conditions. Due to the continuous oil flow in the disk pack, it works best in applications where power density requirements are high, and equipment is extremely abusive. Contact PT Tech for specific application needs.
