NHDI humidifiers use resistive heating elements to provide rapid control with minimum deviation, the company says. Fully variable steam output from 0% to 100% of unit capacity is attained by electronic power control of the heating elements. Designed for operation with deionized water, the unit can control relative humidity to ±1%. The nickel-chromium steel cylinder allows for a controlled, even flow of fresh water to the system when required, without affecting the unit operating control. Each unit is fully micro-computer controlled.
