Why Every Aircraft Owner Should Consider an EngineDehydrator

Especially SkyDry®

“Minimizing Moisture. Maximizing Lifespan.”

Aircraft engines are marvels of engineering built for reliability and performance in extreme environments. However, when the flying stops, a quiet and persistent enemy begins its work: corrosion. For general aviation (GA) pilots and aircraft owners, internal engine corrosion is one of the most costly, yet preventable threats to engine life and value. That’s where an engine dehydrator becomes a powerful tool—and why SkyDry® stands above the rest.

This engine had 413 hrs since major overhaul. The Plane was going through prebuy and the buyer wanted the inside of the engine checked for rust and to make sure the lifters and cam lobes all looked good. Kalamazoo Aircraft ended up pulling a cylinder to get a better look inside the engine. The Plane had hardly flown for 5-10 years, only on flights back and forth to annual inspections. Also, the owner would turn on the engine heater every day for 3-4 hrs during the winter which created a very humid environment for corrosion to
proliferate.

Key Advantages of the SkyDry® System:

  • Active drying cycle: Continuously removes moist air from the crankcase and cylinders and replaces it with dry, filtered air.
  • Proven performance: Studies show that maintaining crankcase RH below 30% significantly slows corrosion—SkyDry® keeps it even lower.
  • Closed-loop architecture: Unlike DIY setups and open systems that allow ambient (potentially humid) hangar air to pass through the desiccant,
  • SkyDry® seals the airflow in a loop, drastically extending desiccant life and preventing contamination.
  • Computer-controlled efficiency: SkyDry® employs a proprietary algorithm to adjust airflow dynamically, delivering maximum drying effectiveness while using minimal power.
  • Once installed, the system runs automatically—giving aircraft owners peace of mind during downtime or seasonal storage.
  • Pays for itself quickly: With overhaul costs ranging from $30,000–$50,000, extending engine life by just 50-70 hours offsets the cost of the SkyDry® system.
  • Reduces Internal Corrosion: Maintains low humidity levels to prevent condensation on internal engine components.
  • Extends TBO (Time Between Overhaul): A 200-500 hour extension can save thousands in overhaul costs.
  • Improves Oil Life: Reduces water and acid in oil, extending oil change intervals by 25-40%.
  • Protects Engine During Inactivity: Especially valuable for seasonal or infrequent flyers.
  • Minimizes Maintenance Surprises: Prevents camshaft and lifter damage from corrosion.
