SETC Series - Outdoor Steam Exchange Humidifier

Condair SETC Outdoor Steam Exchange humidifiers generate, clean, atmospheric steam using facility boiler steam as an energy source. Boiler steam passes through internal 316 stainless steel heat exchangers, turning fresh water into steam at atmospheric pressure. This technique prevents chemical boiler treatments from being dispersed into the building air supply. The compact 316 stainless steel heat exchanger has large flat surfaces to minimize scale buildup in the humidifier tank. Scale tends to fall off the exchanger wall to the bottom of the tank, maintaining efficient heat transfer to the water and extending the intervals between cleanings. The smooth stainless steel surface of the tank and removable heat exchanger are easily cleaned and maintained.

SETC Outdoor humidifiers offer unprecedented installation flexibility. They can be configured for both medium and large systems. Units are packaged in a weatherproof integral enclosure and feature single point pressure steam, water and power connections. Keep warm, freeze protection as well as heating and cooling fans are standard. The standard drain water cooling ensures drain water does not exceed 140°F (60°C) to meet local plumbing codes. Steam distribution is easily accomplished through either the HVAC duct system or into individual areas through remote blower packs.

All SETC Outdoor humidifiers have an automatic system test routine, and a display window that provides readouts on operating parameters and self-diagnostic functions, including service indication. The humidifier will make service adjustments automatically or trigger a shutdown while displaying the function requiring operator attention. SETC Outdoor humidifiers can be easily integrated with a central HVAC control system, via a computer interface, for maximum control flexibility. Humidifiers can accept command inputs from a BMS to automatically control the humidifier’s output.

Condair humidifiers provide clean humidification, reducing air-borne contaminants and subsequent health-related employee absenteeism. Correct interior humidity levels in winter maintain comfort at lower temperatures and can reduce heating costs.
