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. Then 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. Because the disc pack is wet with continuous oil flow, it is best used in applications where power density requirements are high, and equipment is extremely abusive. Contact PT Tech for your specific application needs.
