Clean Room HVAC System – Detailed Description A Clean Room HVAC System is a specially designed heating, ventilation, and air-conditioning system used to maintain a highly controlled indoor environment where temperature, relative humidity, air pressure, airflow, air changes, and airborne particle levels must remain within defined limits. Unlike conventional HVAC systems, a cleanroom HVAC system is designed not only to provide thermal comfort but also to control contamination and maintain the required cleanliness classification. The system continuously supplies filtered and conditioned air while removing contaminated or particle-laden air from the room. 1. Air Handling and Conditioning The process starts with the Air Handling Unit (AHU) , where outside air and/or return air are introduced into the system. The air passes through a series of filtration stages designed to progressively remove dust, particles, microorganisms, and other contaminants. Depending on the application, the AH...
Smart Wastewater Treatment Equipment Smart Wastewater Treatment Equipment is not one single machine; it is an integrated treatment system combining wastewater-treatment equipment, sensors, PLC/SCADA automation, IoT connectivity, online water-quality monitoring, and energy-efficient operation . 1.
