How it works, Summary
Continental and Lycoming  typically rate their engine life from 1600 to 2000 hours of operation
between overhauls on most models.   However, the only owners likely to achieve that kind of rated
performance are those who use their aircraft on a nearly daily basis. Why?  The reason is not the
flying. It is the parking!
A primary culprit for premature aircraft engine overhaul is corrosion caused by condensation within the
engine cavity that occurs after shutdown.  Aircraft engines that are used daily frequently reach their
rated TBO because liquid condensate is boiled off on a regular basis.  Low use rate often results in
reduced engine life.   As the engine cools and the internal temperature drops below the dew point,
liquid moisture condenses out of the vapor and clings to internal engine surfaces. This liquid water then
resumes its ongoing process of eating up your engine from the inside out.  However, if the dew point
can be made sufficiently low, then liquid water will never form.   The engine dehumidifier provides a
continuous positive pressure injection of extremely dry air  on a 24/7 continuous flow basis. Any
moisture in the crankcase air is  recovered from the blow-by vent and returned to the dryer. Passing
over the silica gel removes any residual moisture.
