The world has outgrown traditional hydraulic design
Introducing Fluid Architecture Engineering™ at CONEXPO 2026
The engineering discipline that finally optimizes compact, electrified, automated machines by engineering the fluid and its system architecture first for more efficient hydraulics.
Visit HYDAC at CONEXPO 2026 in Las Vegas, March 3-7, at booth S-81040 to see it in action.
The New Discipline: Fluid Architecture Engineering™ from HYDACA first-principles methodology that optimizes compact machines by stabilizing the fluid architecture before anything else.
Fluid Architecture Engineering™ is HYDAC’s first-principles alternative to traditional, rule-of-thumb hydraulic design. Instead of relying on oversized tanks and energy-intensive safety margins, this rigorous approach shifts the paradigm, prioritizing the fluid environment as a front-loaded design strategy.
Because when you control air, heat, contamination, flow-return behavior, and pressure harmonics, you unlock the full potential of your machine.
Engineered fluid architecture enables:
- Smaller tanks without thermal compromise
- Quieter, smoother operation
- Electrification-ready designs
- More predictable automation
- Greater reliability and uptime
- Optimized space for components and system

Core Elements of Fluid Architecture Engineering™The essential engineering principles behind stable, compact, and electrification-ready hydraulic systems
Machine performance begins long before fluid reaches a valve, pump, or cylinder. It begins with how the fluid is engineered, shaped, conditioned, stabilized, and guided throughout the system. Fluid Architecture Engineering™
is built on four foundational elements.
Air Management & Deaeration
Air is the enemy of electrification, automation, and predictable hydraulics
Entrained air drives instability:
- Choppy actuator motion
- Pump cavitation
- Heat generation
- Noise and vibration
- Unpredictable control response
Architectural deaeration, not oversized tanks, is the modern solution.
When air is engineered out, everything else stabilizes.
Pressure & Flow Harmonics
Hydraulic performance is defined by how pressure and flow behave under real conditions.
Traditional hydraulic design treats flow paths as plumbing. Fluid Architecture Engineering treats them as a dynamic systems. By shaping how flow harmonics, return-line behavior, and pressure transients, OEMS can achieve:
- Smoother motion
- Quieter operation
- Better automation performance
- Reduced shock loads
- Smaller reservoirs
This is essential for compact, electrified, and tightly packaged machines.
Thermal Stability & Energy Behavior
Heat is not a byproduct, it’s an architectural variable.
Thermal swings accelerate oxidation, cause viscosity shifts, and destabilize electrification performance. Engineering temperature control into the architecture results in:
- More efficient power use
- Longer fluid life
- Improved component reliability
- Quieter systems
- Lower stress on pumps, seals, and actuators
A stable temperature profile is foundational for a stable machine.
Fluid Health & Cleanliness
Clean fluid is not maintenance; it is critical design.
High-efficiency filtration is essential to achieving predictable performance in modern environments with tighter tolerances and electrified systems.
SUSTAINMICRON, HYDAC’s new, next-generation filtration technology, contributes to this foundation by:
- Maintaining lower ISO codes under high cycling
- Reducing contamination-driven failures
- Supporting compact system design
- Improving long-term efficiency and reliability
When the architecture is engineered, machines perform better.
Fluid Architecture Engineering transforms how machines are designed by stabilizing the fluid system before any mechanical optimization begins.
This is the shift the industry has been waiting for.
How Fluid Architecture Engineering™ Enables Efficient Hydraulics at Any Stage of Machine Development
Efficient hydraulics isn’t achieved through bigger pumps, tighter tolerances, or isolated component upgrades. It comes from the fluid environment, so the entire system behaves more predictably, wastes less energy, and delivers the performance modern machines demand.
This is what Fluid Architecture Engineering™ makes possible, and OEMs can begin applying the discipline no matter where they are in the design cycle. HYDAC supports multiple points of entry aligned to your platform’s maturity. Whether you’re improving a single function or designing a new machine, efficiency starts with the same truth:
Hydraulic performance is based on fluid behavior. And, fluid behavior needs to be engineered, not assumed.
Component-Level Improvements for Existing Platforms
Component-Level Improvements for Existing Platforms
For OEMs optimizing machines already in the field, even small improvements in the fluid environment can yield reduced air, improved thermal stability, corrected return-flow dynamics, and more efficient filtration, unlocking measurable gains in efficiency and reliability.
Fluid Architecture Engineering identifies where the existing architecture is working against you and applies first-principles corrections that:
- Reduce heat generation
- Lower losses
- Improve responsiveness
- Extend component life
These are efficiency gains rooted in architecture, not component swaps.
Subsystem-Level Optimization to Re-Engineer Critical Functions
Subsystem-Level Optimization to Re-Engineer Critical Functions
For OEMs improving the performance of specific functions, subsystem-focused application of the discipline examines how fluid moves, stabilizes, and interacts inside a target function like lifting, steering, articulation, or lowering.
Here, HYDAC applies architectural corrections to:
- Improve controllability
- Reduce energy waste
- Enhance operator smoothness
- Resolve dynamic instabilities
This is where “efficient hydraulics” becomes visible to operators and measurable to OEMs.
Holistic Design of the Entire Fluid Architecture
Holistic Design of the Entire Fluid Architecture
For OEMs developing new platforms or modernizing entire product lines, the full expression of Fluid Architecture Engineering rethinks hydraulic performance before hardware is selected.
Holistic application of the discipline can:
- Deliver 40-50% efficiency gains
- Shrink powertrains and tanks
- Stabilize electrified systems
- Reduce noise and vibration
- Make automation (and maintenance) more predictable
- Create smoother, safer operator experience
- Lower lifecycle cost structures
These are not outcomes that better components alone can achieve. They are the result of a holistic engineered fluid architecture.
