Humidification & Humidity Control: Benefits, System Types, and Maintenance


Humidity control plays an important role in maintaining healthy, comfortable conditions for occupants, preventing damage to electronic equipment, furniture, wood floors, etc., and supporting productivity within that environment. Properly-controlled relative humidity (RH) can be especially critical in specialized environments. These can include computer rooms (to control static electricity), operating rooms (for staff and patient comfort and to reduce the risk of infection), environmental chambers (to aid in research and development), and printing facilities (to control moisture content in paper).


There are several types of humidification systems, including steam canister (the most common), ultrasonic, infrared, and dry fog. One of the most important components to achieving good humidification system performance is using pure, softened water to prevent mineral deposits and malfunction. Good-quality water can make the difference between a clean, well-running humidification system and a service-and-maintenance nightmare. Utilizing high-quality humidistats, such as those from Vaisala, is critical as well. These sensors, which are typically placed in return or exhaust ductwork, must be calibrated regularly to ensure that RH levels are properly controlled.


Without the required knowledge and experience in humidification systems, instrumentation, water treatment, and maintenance procedures, humidity control can pose formidable challenges. PJM Mechanical is a recognized expert in the installation, service, and maintenance of humidification systems in large commercial, corporate, pharmaceuticals, food manufacturing, healthcare, and other specialized environments and can help clients achieve and maintain the proper RH for their facility.
