When RH reaches levels below 35%, static electricity may develop on surfaces and materials. Static electricity is not only annoying; it can wreak havoc on computers by burning microchips, and wiping out memory cards. Elimination of static electricity also greatly reduces the risk of solvent fires in the printing industry - commercial presses develop extraordinary amounts of electricity at the roller and ignite solvents in the ink wells. And if you ever wiped your finger across your television screen you know that static electricity attracts dust, a real problem in the plastics and films manufacturing process where dust can ruin a product or in the healthcare industry where dust can kill.
Indoor Air Quality affects man and machine and both operate best at optimum environmental conditions and IAQ and IEC standards are forcing manufacturers and building owners to adjust their management of air quality control. If a building's main HVAC system does not have the capacity to maintain RH levels within a comfort zone of 50% to 60%, then proper humidification can help reduce adverse effects of occupant discomfort, bacteria growth, viruses, fungi, mites, allergic reactions, respiratory infections, chemical interactions and ozone production.
Type of Humidification Process
The type of humidification process used can make a significant difference in maintenance and operation costs. Learn the difference between adiabatic/evaporative vs isothermal/steam humidification.
