How the Humidifier Works
The Nortec SETC/P is an atmospheric steam generator that uses energy from pressurized
steam flowing through a heat exchanger submerged in water to generate steam. The
Nortec SETC/P is designed for air humidification via steam distributor, blower pack, or steam
manifold (Nortec SAM-e).
Steam Generation
 After initial start-up and tank filling the humidifier will sit in standby mode, awaiting a call for
humidity.
 When a call is received, the humidifier will send a signal to the electric actuator. The
actuator will open as required and the flow of boiler steam will begin.
 Energy from the boiler steam is transferred to the fresh water tank through a heat exchanger
inside of the unit. This causes the water to boil. Full boil from a cold tank can take up to
15 minutes. On Nortec SETC models, the Keepwarm feature can be activated to reduce boil
time, see Idle Mode on page 52.
