Measurement of Oxidation stability. Komatsu Oil and Wear Analysis (KOWA) is the spearhead of our Condition Monitoring Services (CMS). Your equipment is the lifeblood of your business and KOWA works like a blood test for your machine. There are normal wear rates for each moving component and as these parts wear particles appear in the oil. These particles are small but easily detected through regular KOWA use. KOWA highlights increases in the quantity of contaminants and can identify areas of concern, allowing preventative action before a failure. Continued and consistent KOWA use will provide a clear picture of your machines health, potentially saving you valuable time and money.
