# INNAS — Hydraulic Engineering Innovation

> INNAS is an independent engineering consultancy founded in 1987, based in Breda, the Netherlands. The company focuses entirely on hydraulic innovation — developing and licensing new hydraulic technologies that are more efficient, quieter, and better suited to modern energy demands. INNAS does not manufacture products; it invents, proves, and licenses them.

INNAS has developed three core technologies: the Floating Cup principle (a radically improved axial piston pump/motor design), the FCT45 hydraulic transformer (a power converter for hydraulic systems), and CPR-systems (Common Pressure Rail hydraulic architectures). These technologies are offered for licensing to OEMs and system integrators worldwide.

## Core Technologies

- [Floating Cup](https://innas.com/technologies/floating-cup): Axial piston pump/motor with up to 97% efficiency, 500 bar peak pressure, zero minimum speed, and very low noise. The foundation of INNAS technology.
- [FCT45 Transformer](https://innas.com/technologies/fct45-transformer): Hydraulic power converter built on the Floating Cup principle. Converts and controls hydraulic power with minimal loss — the enabling technology for CPR-systems. Being made available for testing in 2026.
- [CPR-systems](https://innas.com/technologies/cpr-systems): Common Pressure Rail hydraulic architecture. Delivers ~40% fuel savings and ~60% less heat generation compared to conventional valve-controlled hydraulics. Works with any power source including batteries.
- [Shuttles](https://innas.com/technologies/shuttles): A simple, low-cost add-on to standard swash plate pumps that eliminates commutation losses and raises peak efficiency to 96.4%.
