Steam Humidifier
A steam powered humidifier has a heating element that boils the water in the reservoir when the humidistat calls for humidity. It's the best type for providing precise humidity control in high demand conditions because it can deliver humidification regardless of whether or not the furnace is running. Many businesses have valuable inventories and specific processes that require protection and consistent humidity regulation. Most businesses rely significantly upon electronics to conduct day-to-day operations, which means keeping humidity at constant levels to reduce static electricity.
