HPTO® – Dry Clutch

HPTO Dry Disc Pack Clutches engage by “bumping” the clutch, much like an over-center lever actuated clutch, but without a lever. This engagement sequence involves a series of pulses to bring the driven load up to synchronous speed with the engine. 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 dry, it is best used in applications where power density requirements are low, and equipment is less abusive. Contact PT Tech for your specific application needs.
