Surveys have documented that water or moisture is the second largest contamination (after particles) in oil systems. Water has a damaging effect on the life time of oil and system components:     
   * Reduced oil film strength and lubricity   
   * Corrosion 
   * Hydrogen-induced fractures (embrittlement or blistering) 
   * Fastened oil degradation which will speed up the oils oxidization 
The effect is damages to engine parts, cylinders, bearings, etc with resulting mechanical failures and therefore repairs and expensive downtime costs (ranging between EUR 10,000 - 200,000).
