STS® Humidifier

DriSteem’s STS® (steam-to-steam) humidifier creates chemical-free humidification steam using boiler steam as its energy source. Boiler steam in the heat exchanger vaporizes clean fill water into humidification steam. No boiler steam or chemicals ever enter the humidified space, instead they return to the boiler.

Controlled by:

Dispersion devices:
