Through the ANAC Coolant service, the ANAC offers a fluid analysis service system for cooling liquids. It is an in-depth diagnosis for the follow-up of cooling liquids and cooling systems.

ANAC Coolant is recommended in the following cases:

  • Detailed follow-up of the coolant behavior and the condition of the system the cooling liquid is operating in.
  • Punctual analysis and diagnosis in certain cases (breakdown, complaint, expertise...)
  • Compliance check of the properties of the cooling liquid in use with the new cooling liquid.


ANAC Coolant determines the physical chemical properties of the cooling liquid and its protection against corrosion and temperature. The ANAC report gives information such as appearance, pH, reserve of alkalinity, hardness of water, density.

Protection against temperature:

Ratio antifreeze/water, freezing and boiling temperature

Corrosion of the cooling system:

Spectrometric determination (ICP) of elements: Fe, Pb, Cu, Sn, Cr, Al, Ni (ppm)

Protection against corrosion:

Determination of the concentration corrosion inhibitors, organic and mineral.


COOLANT + Pollution by sediments:

Detection and qualification of the pollution by solid particles (of medium and big dimension >5μ) by filtration and microscopic observation.


The ANAC diagnosis report is available within 5 days after reception in the lab. The results are dispatched by e mail and can be viewed on the Internet. In urgent cases, the ANAC can send the report by fax immediately after the diagnosis.
