Important - Wet Air Outlet duct arrangement for all desiccant dehumidifier installations
System 1 Desiccant dehumidifier type DC installed within the dehumidified room. Fresh air input (optional) can be used to provide a positive pressure in the room. A negative pressure can be created by omitting the reactivation inlet duct.
System 3 Desiccant dehumidifier type DC installed outside the dehumidified room. Fresh air input (optional) can be used to provide a positive pressure in the room.
System 2 Desiccant dehumidifier type R with internal heat recovery, installed within the dehumidified room. Fresh air input (optional) can be used to provide a positive pressure in the room. A negative pressure can be created by omitting the reactivation inlet duct.
System 4 Desiccant dehumidifier type R with internal heat recovery, installed outside the dehumidified room. Fresh air input (optional) can be used to provide a positive pressure in the room.
System 5 Desiccant dehumidifier type DR with internal heat recovery, installed within the boundary walls. Process inlet damper adjusted to create positive pressure in the dehumidified room (if fresh air duct is omitted, the room will operate under negative pressure).
System 6 Desiccant dehumidifier type DR with internal heat recovery, installed outside the boundary walls. Dampers are adjusted to create a positive (or negative) pressure in the dehumidified room.
System 7 Desiccant dehumidifier type R with internal heat recovery, used to blow air into or through an object (total loss system).
System 8 Desiccant dehumidifier type DR with internal heat recovery, used to blow air into or through an object (total loss system).
