Nortec GSTC Outdoor Gas Steam humidifiers provide clean steam humidification at an economical operating cost. This Isothermal System produces mineral free, odorless, sterile steam. Steam is generated at atmospheric pressure inside a fully insulated stainless steel tank. The combustion system utilizes a modulating forced draft combustion air blower, a negative pressure regulator gas valve and a 100% premix burner. 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.

GSTC Outdoor humidifiers offer unprecedented installation flexibility. They can be configured for both medium and large systems. All units arrive completely assembled in a weatherproof integral enclosure for installation ease. Keep warm, freeze protection as well as heating and cooling fans are standard. All capacities feature single point water, power, gas connection and steam connections. 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 GSTC 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. GSTC 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.

Nortec 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.
