Salt Fog Cycle

• Hot, humid air is created by bubbling compressed air through a bubble (humidifying) tower containing hot deionized water.
• Salt solution is moved from the 60-gallon reservoir through a filter to the nozzle by a gravity-feed system.
• When the hot, humid air and the salt solution mix at the nozzle, it is atomized into a corrosive fog. Fog is distributed by the Unifog dispersion system.
• Strip heaters maintain the programmed set-point temperature.

SALT FOG AND HIGH HUMIDITY CYCLES

High Humidity Cycle
During the humidity cycle, the chamber operates much like the salf fog cycle, except that deionized water is fed to the atomizer nozzle rather than salt solution. This creates a 100% relative humidity condition in the exposure zone.

Dry Cycle
For a low humidity state in the exposure zone of the chamber, air is forced into the exposure zone via a blower motor which directs air over the energized chamber heaters. Chamber temperature is set by the user and controlled by the PLC.

DRY AND DWELL CYCLE

Dwell Cycle
During the dwell cycle, no action is taken by any of the chamber components.
