🔍 Key Concepts

• Corrosion and oxygen exposure inside evaporator shells during long idle periods • Effects of stagnant salt water versus dry metal surfaces over time • How manufacturers recommend securing flash-type evaporators (marine distilling plants) when laid up

💭 Think About

• What happens to the internal metal surfaces if moisture and air are both trapped inside the evaporator for weeks or months? • Would leaving chemicals or salt water inside for a long period help preserve the equipment, or create additional damage or safety hazards? • Think about what condition you want the internal surfaces to be in when you restart the system after a long lay‑up.

✅ Before You Answer

• Which option best minimizes corrosion risk over a long, unattended period? • Which choice would be unsafe or impractical to maintain for an extended lay‑up? • Eliminate any option that would leave salt deposits or aggressive chemicals sitting in the unit for a long time.
