An industrial humidifier is a system that is capable of providing adequate humidity levels in a manufacturing environment. High-speed production processes add to the heat load in a building, bringing down the humidity. This can lead to a dangerous buildup of static electricity in a plant where dust and other flammable materials may be in the air. Processes such as woodworking, printing, and electronic and microchip fabrication, — which involve gluing, coating, and bonding — benefit from humidity control. Energy efficiency is also a consideration with an industrial humidifier.

Related products include industrial steam humidifiers, as well as electric-powered and gas-fired models. Steam heat exchangers use a heat source for producing steam from tap water or pure water reserves. These are also designed to comply with indoor air quality requirements to ensure proper humidity levels along with clean air for workers.

Industrial humidifiers are also designed as fog systems that integrate with building automation systems. In this configuration, an industrial humidifier system can be integrated above the factory floor, with the moisture released via fog nozzles. This is a viable alternative to humidifying air traveling through ducts, because excessive heat loads can be managed at the source.

An industrial humidifier also can be a contamination control system. It can be capable of utilizing adiabatic humidification to control humidity and airborne particles, and reduce the buildup of electrostatic discharge that, when combined with particulates, can be a health hazard and a cause for major industrial accidents. Along with proper treatment of supply water, an industrial humidification system ensures a safe environment in which to work.

An industrial humidifier can be found in many manufacturing facilities. Plants that make electronic assemblies require humidification, because the air in buildings producing circuit boards and computer equipment must be free of particles. Semiconductor manufacturing is another major application, because integrated circuit printing requires tightly controlled temperatures, along with a relative humidity (RH) of around 35 percent to 45 percent with acceptable tolerances within a range of 1/2 percent to 5 percent RH.

It is also used in medical supplies manufacturing and in automotive and industrial paint plants that utilize spray booths. Waterborne paint provides many benefits, but it is extremely sensitive to humidity changes and requires the use of an industrial humidifier. An industrial humidifier is larger than the kind that would be found in a home and is capable of precise levels of control required by industrial processes.
