High Humidity<br />
Ambient Air<br />
• Hydraulic system oil and air inside reservoir heat up<br />
• Moisture carrying capacity of the air inside reservoir rises<br />
• Moisture condenses on cooler reservoir surfaces<br />
• Air inside reservoir cools to ambient temperature<br />
• Remaining excess moisture condenses causing oil<br />
degradation, machine wear and eventual failure<br />
