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.
