Nortec LiveSteam humidifiers are pre-engineered systems designed to control and distribute steam under pressure, from a facility steam boiler, for direct introduction into a duct or Air Handling Unit. The Steam distributors are constructed of high quality 304 stainless steel and can be configured for single or multiple configurations. LiveSteam distributors are available in a wide variety of lengths ranging from 12" to 144" to suit your duct size for the best possible steam dispersion. Superior tube in tube design ensures maximum jacketing (97%), thus preventing condensate discharge, while maintaining the preferred round shape. Optional stainless steel insulation jacket encompasses 1/2" fiberglass insulation to improve efficiency and minimize heat transfer to the air stream. B2C
