Fluxes and coolants – Not the best of friends

Publication year: 2023

Aqueous coolants are extremely important in ensuring the safe operation of engines, converters and many other systems. But during use, their condition changes due to ageing and contamination. In the past, examinations using handheld devices and measuring strips were carried out on site to check antifreeze and heat transfer properties and to find signs of degrading basic protection additives. 

Monitoring with OELCHECK all-inclusive analyses goes far beyond this and ensures a high level of safety when using coolants. This is because, provided that regular analyses are carried out, we can now not only detect existing corrosion, but also interpret indicators of its future formation and warn of impending damage. The fluxes used when soldering the coolers also continue to play a key role here! 

Engines, converters and many other technical components need to be protected against overheating. The heat lost during operation is dissipated, thereby cooling the components. This is done with the help of air, water, cold mixtures with special salt compounds or coolants, which in most cases are based on glycol. The latter are not just used for radiators in motor vehicles. Aqueous glycol-based coolants are also used in cooling systems for wind turbines, locomotives, stationary engines (such as in energy generation using biogas) or in power supply converters.
