Tank Optimisation Platform Save space. Save weight. Save costs.

Save costs and energy with HYDAC – with the innovative HYDAC solution for tank and space optimisation for mobile machinery and various industrial solutions.

HYDAC Air-X technology – the solution for saving space and reducing CO2How to save costs and energy with HYDAC

In every existing tank system, we see potential for optimising and reducing the size of tanks.

  • Optimising of tank size by 30–40%
  • Cost reduction by reducing complexity and material use
  • CO2 reduction
  • More reliable machine availability
  • Original HYDAC product quality

Benefit from our extensive specialist knowledge and from profession tools such as customised test benches and simulations in the HYDAC FluidCareCenter® and in field measurements on site.

HYDAC Air-X technology enables significant tank reduction

To reduce the tank size, the system needs perfect air separation. This can only be achieved by combining the tank with an optimised filtration strategy. Our innovative Air-X technology offers a range of features that ensure maximum air separation in the system:

  • Low discharge velocities
  • Reducing oil turbulence in the tank
  • Uniform mixture of oil in the tank
  • For flow entry from below, an outlet above oil level is possible
  • Coalescence of the air bubbles at integrated degassing windows and thus faster separation

Only using Air-X technology makes it possible to construct the tank with more compact dimensions – combined with improved air separation – as the follow video demonstrates:

The advantages of using Air-X technology:

Reduced installation space

Additional space

thanks to smaller tanks

Reduced costs

Lower costs for OEM

thanks to less oil and steel and thus reduced piping and screw connections

Reduced weight

Lower costs for end customers

thanks to less oil use and longer oil intervals

Conservation of resources

Improved carbon footprint and use of resources

as less oil and steel is used in manufacture


Improved machine reliability

thanks to maximum air separation and avoiding the problems air can cause in the oil 
such as corrosion, accelerated oil degradation and cavitation

HYDAC offers a wide range of services and customer service In addition to the innovative Air-X technology, we offer extensive consultation and services:


We provide various simulations for computer-aided optimisation of systems. This includes simulations of:

  • Flow
  • Degassing
  • Swashing

Lab and field tests

We also perform experimental testing of tank systems in the laboratory or directly at the machine in the field. We have a unique specially developed air-content sensor that we can use for this purpose.

Individual consultation

In our development centre, the HYDAC FluidCareCenter®, we pool our filter expertise and application knowledge with our extensive experience in the topic of “air in oil”. We will gladly provide you with expert individual consultation regarding tank optimisation.
