The Humicontrol gas-powered, steam humidifier has 25% to 100% modulation with 94% combustion efficiency, says the manufacturer. The humidifier can automatically detect excessive mineral scale build-up on the heat exchanger. A water preheat circuit allows the unit to respond in seconds, the company says. Able to handle any kind of water, including demineralized, the Humicontrol can use natural gas or propane and can be adjusted in the field, according to the manufacturer. The steam generator is made of 316 stainless steel and the heat exchanger is composed of a cast aluminum alloy with Teflon® coating.
