A steam humidifier boils water and distributes the vapour into an air stream or space. The generator's capacity is only one part of the system. Steam must be delivered and absorbed without wetting ducts, filters or nearby surfaces.
Electrode and resistive units use water differently
| Heating approach | Procurement implication |
|---|---|
| Electrode | Current passes through the water, so conductivity and the manufacturer's permitted water range are central to operation. |
| Resistive | Heating elements boil the water; permitted water treatment and cleaning arrangements depend on the unit's design. |
Do not add demineralised water to an electrode unit on the assumption that purer water is always better. Conversely, hard water can increase mineral accumulation and maintenance demand in equipment that accepts it. Follow the selected generator's water specification.
Plan the distributor before fixing the cabinet position
Steam-line routing, condensate drainage and distributor placement affect delivery. A long or poorly arranged connection can lose heat and collect condensate. Within a duct, available absorption distance depends on the entering air and distribution arrangement.
Place humidity sensing and limiting controls so they represent the process without allowing local saturation. Airflow proving and shutdown behaviour should be coordinated with the air-handling system.
Compare the maintenance workload
Include cylinder replacement or cleaning, heating-element access where relevant, drain connections and safe handling of hot water. Capacity should cover the moisture load with suitable control at low demand, rather than encouraging frequent on/off operation.
Condair's electrode humidifier engineering manual addresses water conductivity and the steam-generation arrangement. The quoted package should identify its actual heating method, permitted water quality and servicing requirements.
