For more than 40 years, Danfoss has been developingstate-of-the-art components and systems for mobilemachinery used in off-highway operations around theworld.

We have become a preferred supplier by offering thebest of what really matters: The hardware inside yourvehicle application.

H1 - our new generation of servo-controlledhydrostatic pumps and bent axis variable motors is noexception.

The H1 product is built around an advanced controland available in a wide range of displacements. It isdesigned for quality and reliability and offersexpanded functionality, greater total efficiency, andeasy installation.

All H1 control and sensor options are PLUS+1®

Compliant. PLUS+1® allows you to rapidly developand customize electronic machine control. It opensup the future by combining machine controls anddiagnostics in an integrated operating network.
