The company has added Version 1.7 software to its line of heaterSteam heating element humidifiers. One key feature is the algorithms that enable the heaterSteam to achieve a control precision of ±1% with full modulating range of 0% to 100% on virtually any water quality, including demineralized and softened. This makes the unit well-suited for precision applications and applications where requirements can vary quickly, such as with 100% outside air.
