EHA provides power dense, low-noise performance in an affordable package.  The robust, leak free, one-piece housing design delivers system simplicity and lower installation costs.  The small footprint reduces space and weight claim.  EHA allows decoupling from main hydraulic system reducing parasitic losses for better fuel efficiency and lower operating costs.   It eliminates hoses, fittings, valves and fixtures and is easy to integrate into larger systems.  The extended service life dramatically lowers maintenance requirements and costs.  The EHA comes pre-flushed, filled and sealed and operates in a variety of harsh environments.

Easy to Install and Connect

Compact EHA is designed to make commissioning as simple as possible. The motor is connected to a suitable power supply and switching circuit, and the rod or base end is secured with a pivot pin. The unit is then actuated to align the opposite pivot pin connection, and the pin inserted to secure.  And that's it – your Compact EHA is ready for use.

Maintenance

Because the Compact EHA is flushed, filled and sealed for life, there is virtually no maintenance required. This, in combination with the anodized housing, stainless steel rod and rugged seals and components, provides a longer service life with reduced warranty costs.
