The Aprilaire® Model 800 Canister Steam Humidifier delivers humidity in the form of steam to the conditioned space via the HVAC system ducting. The humidifier generates steam by energizing two electrodes that extend into a canister of water. Current flowing between the electrodes causes the water to boil, creating steam. Water is introduced to the humidifier through a fill valve to a fill cup located in the top of the cabinet. The fill cup serves as an overflow reservoir and provides an air gap between the humidifier and water source. The drain and fill valves work together to maintain water level in the canister to deliver the rated steam capacity based on the electrical conductivity of the water and to temper drain water.

Steam humidifiers are optimal for large homes, homes with a large amount of woodwork, they use less water than most bypass and powerfan humidifiers. Also, steam humidifiers are the best performing humidifier type when paired with an all electric system such as a standard heat pump and air handler.

Steam is delivered into the airstream through a dispersion tube mounted in the HVAC system ductwork. Openings in the dispersion tube are fitted with “tubelets” which extend into the center of the tube. The design of the dispersion tube and tubelets distribute steam over a wide area in the duct and direct any condensed moisture back into the steam hose.
