Humidification is key to most HVAC systems serving hospitals, laboratories, schools, manufacturing, and pharmaceutical facilities. These systems need to be designed, installed, started, and commissioned to ensure that they provide the required moisture, are under control, have the required safeties, and will perform over the life of the HVAC system. Unfortunately, every year, we see issues with humidifiers not performing as required, humidifiers that are mid-sized, incorrectly installed, missing the required controls, and, most importantly, missing the required safeties to ensure the system can operate without causing issues in the ductwork or at the space level. This is for new, renovation, and retrofit projects. This course will give the attendee a basic understanding of humidifier selection, installation, operation, essential items to look for, possible issues, and solutions to those issues.
