Steam Humidifiers

Steam humidifiers are used for controlled steam injection into air streams or enclosed areas in industrial facilities where relative humidity is a critical operating parameter for production, storage, or equipment performance. Typical applications include HVAC systems in industrial buildings, pharmaceutical plants, food processing areas, printing, timber handling, raw material warehouses, and other spaces where low humidity can affect dimensional stability, electrostatic charge, or product quality.

This category covers ADCA DSH direct steam injection humidifiers. Selection should be based on the required humidification load, steam pressure and steam quality, air flow rate, air temperature, available absorption distance, allowable condensation inside the duct, and the required control accuracy for relative humidity. In steam systems, upstream filtration, correct pressure reduction, condensate drainage ahead of the humidifier, and proper positioning of the injection point are necessary to prevent droplet carry-over and wetting of duct walls or downstream filters.

Available versions include DIN and ANSI configurations, with pressure class PN16, stainless steel construction, and sizes 1/2", 1", and 1 1/4". Connections include female threaded ISO 7 Rp or NPT ends, while flanged or special connections are available subject to configuration. During maintenance, attention should be given to nozzle or dispersion tube cleanliness, steam control valve operation, connection tightness, condensate removal, and correct response of the humidity sensor and controller.
