DesiCan 1000

General Aviation engines, such as those made by Lycoming and Continental, are prone to corrosion and rust damage inside the engine. Since moisture is a natural byproduct of combustion, experts report that at engine shutdown relative humidity is over 80%. This moisture remains in the engine and as the engine cools, moisture condensates on internal engine parts. This residual moisture has nowhere to go until the engine is run again and heated thoroughly, causing corrosion to the engine cavity. Airplanes with low use and those in highly humid climates, such as here in the Southeast, are most susceptible. However, experts warn that since the moisture results from combustion and is a function of dewpoint, this also occurs to airplanes in dry and cold climates.

We have developed a simple and economical, closed loop system that runs dry air through the engine, removing unwanted moisture.  Our custom-made Desiccant-based system uses a Silica Gel that serves as a drying agent to pull moisture out of the engine and captures it in a closed container, greatly reducing the amount of moisture remaining in the engine that could cause corrosion and rust.


A digital hydrometer lets the owner see the internal humidity level. Humidity levels can be reduced over 75%, greatly reducing corrosion and rust formation on the engine components. The silica product will change color when it goes from dry to wet, indicating time to “recharge” the drying agent.


The DesiCan 1000 base version starts at only $200. Compare that to OEM versions that can cost over 3x ours.
