Equipment location is critical

An isothermal humidification system includes a pressurized steam boiler or an evaporative steam generator, control components, and a dispersion assembly. While an evaporative steam generator or atomizing pumping station can be placed in numerous locations, proper placement of the dispersion assembly and control components is crucial.

Know absorption distance to choose dispersion assembly
Available absorption distance is the key factor affecting dispersion assembly choice. In AHUs or ducts, dispersed steam or mist must be absorbed into the air before contacting duct elbows, fans, vanes, filters, or any solid object, or dripping will occur. For example, if there is 10 ft of available unobstructed duct or AHU length downstream of the dispersion assembly, several types of dispersion assemblies will achieve absorption within that distance. Applications with 18 in. or less of available unobstructed duct or AHU length downstream of the dispersion assembly have fewer dispersion assembly choices to achieve absorption. Know the available absorption distance before selecting equipment.

Be aware of operating sound characteristics when choosing system component locations. Steam generators, pressurized dispersion assemblies, and adiabatic pumping stations generate some noise. Dispersion tube assemblies and fans generate minimal noise. Isolate noise-generating equipment is areas where noise isn't an issue. Connect to fans in open spaces or dispersion assemblies in ducts and AHUs with piping or hose.

Provide maintenance access
Choose a location that allows access to equipment for convenient visual inspection and maintenance. Pressurized steam dispersion systems include devices (such as a steam control valve, a steam trap, and a strainer) that require periodic maintenance. While these devices can operate for long periods without attention, they must be accessible for inspection.

Depending on makeup water type, evaporative steam generators require periodic cleaning or cylinder replacement, so allow room for access to cleanout plates and cover removal.

Electrical components are housed within the humidifier cabinet or located remotely. Allow 36 in. clearance in front of electrical panels.
