As a leading laboratory, we analyse the quality of lubricants in Europe and the Far East and generate accurate diagnoses. As the fi rst laboratory in Germany to research coolant and anti-freeze agents, we are now offering our customers another completely new service. Aqueous coolants are essential for the safe operation of engines and many other systems. It is not without reason that leading engine manufacturers have drawn up detailed specifi cations for coolants and engine coolants. The regular checking of these agents is becoming increasingly important, and with the new OELCHECK analyses, everyone is on the safe side!
From now on, OELCHECK is also studying glycol-based coolant mixes and concentrates, frost and corrosion protection as well as heating and preparation water. To analyse these media, we have invested in additional test devices and installed our own water laboratory within our lubricant laboratory. Most devices used for water analyses are in fact also used for oil analyses, yet measuring methods and calibration are entirely different in this regard. Just as for oils, we have compiled special OELCHECK analysis kits for checking coolant and anti-freeze agents with which almost all practical- related questions can be covered. Modern coolant concentrates are mostly based on ethylene glycol and are free from nitrates, amino acids and phosphates. They contain a cocktail of special additives, with which they reliably suppress cavitation and are able to achieve the required long service life. In addition, they must be compatible with the up to 100 materials which can be built into a coolant system. Coolants ensure optimal heat supply and dissipation, protect against corrosion and cavitation as well as deposits and reduce freezing at sub-zero temperatures, and are used in motor vehicles, construction machinery and locomotives as well as in wind turbines and stationary diesel, natural gas and special gas engines. In order to ensure operability over a long period of time and therefore the safe operation of the cooled units, OELCHECK investigates all important parameters.
