Fluid Conditioning

Filtration, Decontamination & Purification of hydraulic fluids.

The “Fluid Conditionning“ division of EXAGO GROUP responds to all issues related to Filtration, Decontamination and Purification of hydraulic fluids.

We offer various technologies that we control for several years and which can meet all the needs of fluids applications : Reduction of solid pollution, obtaining and measuring cleanliness classes, monitoring and control, removal of water in all its forms or foreign oil regardless the volumes to be treated, decontamination of installation, hoses and pipes.


Fluid analysis, issues identification, analysis reports.

A good understanding requires taking into consideration the whole system: the objectives setting, the treatment systems chosen, the installation constraints and the fluids chemistries used.

Only a good awareness of all these parameters can result a comprehensive and effective solution.

LABORATORY OF OIL ANALYSIS, CONTROL SOLUTIONS, PARTICLE COUNTER: Diagnosis and monitoring of all oil parameters.
