Microprocessor Controlled Hydraulic Clutch

The HPTO12 is a hydraulically applied dry friction clutch designed for off-highway diesel engine driven equipment. Its hydraulic design eliminates the need to adjust the clutch throughout its wear life. The HPTO12 comes in a long version (HPTO12TD) designed to be a drop-in replacement for existing market products, without the need for problematic outboard support bearings, as well as a short version (HPTO12TS) designed to be as short and compact as possible. HPTO12DD and HPTO12DS version are also available for direct drive applications.

Clutch Controller

The microprocessor based clutch controller designed entirely by our in-house controls department allows for a consistent engagement sequence every time, extending the life of the clutch. 

The HPTO12 utilizes PT Tech’s Basic3 controller which can be integrated into the equipment’s control system via the SAE J1939 CAN-bus protocol. The Basic3 control system also incorporates the proven energy management capabilities that have been extremely successful in our wet clutches and brings this control and protection to the dry clutch market. 

The start-up sequence uses patented engagement logic involving a series of “bumps” in order to quickly bring the output inertia up to a synchronized speed with the engine while keeping the energy level in the disc pack within design limits. This allows the HPTO12 to start equipment with a large amount of inertia; even under partially jammed conditions. 

The HPTO12 package increases equipment reliability and profitability with a consistent and monitored startup process every single time.
