Coolant analysis
ANALYSIS & DIAGNOSTIC OF COOLANT (or thermal fluid)
The role of the coolant is multiple. For example, in a thermal engine, it allows to cool the engine against local superheating and it warms up faster the engine.
The coolant is known to be used in the thermal engines of vehicles or machines, but it is also widely used in the industries using thermal processes allowing to cool or to warm. In this case, the coolant is present in very important quantity (up to 30 000 liters).
Coolant analysis allows to determine and control all properties and characteristics, to verify its quality and its stability over the time to avoid breakdowns. Indeed, the coolant tends to lose its qualities over the time and so can damage parts of the circuit.
ANALYSES AND CHECKED POINTS (EXAMPLES)
Several elements are checked in a coolant analysis, such as :
- Density at 20°C
- Percentage of antifreeze agent and water
- Aspect and color
- Freezing point and boiling point
- Water hardness and pollutants (quality of the used water)
- pH (it can reveal the presence of exhaust gases)
- Reserve of alkalinity (control of the capacities of the coolant to neutralize the acid)
- Spectrometry (check of the absence of intern oxidation of the circuit, ..)
- Inorganic and organic inhibitors (technology of the fluid)
- Glycol degradation (ageing of the coolant)
- Gravimetry (allows to verify the cleanliness of the coolant)
INTERPRETATION OF RESULTS / DIAGNOSTIC
From results of analyses transmitted by our laboratory, our team of diagnosticians-consultants will provide you with a detailed and reliable diagnostic on the state and the properties of the coolant and with customised recommendations.
IESPM recommends to realize a coolant analysis each year on strong power engines and in industrial circuits (hot/cold).
