Modern commercial buildings, industrial facilities, and public infrastructures rely on complex HVAC duct networks for ventilation, air conditioning, and air exchange. However, unprotected duct penetrations through fire walls, partition walls, and floor slabs become hidden fire spread channels. In case of fire, flames and high-temperature smoke can rapidly propagate along
High-temperature industrial circulating water systems, boiler equipment, petrochemical pipelines, and seawater desalination facilities face severe scaling, sludge deposition, and medium corrosion challenges under long-cycle and high-load operation. Conventional water treatment dispersants often fail at high temperatures and high alkalinity, leading to hard scale accumulation, reduced heat exchange efficiency, pipeline blockage,
Precise airflow measurement and accurate volume regulation are the core keys to qualified HVAC and ventilation engineering. Traditional square volume control dampers struggle with precise adjustment and airflow data reading in circular duct systems, often causing unbalanced air distribution, difficult system debugging, and unstable indoor air pressure. AnIRIS Damper, also
Industrial open and closed circulating water systems, including HVAC cooling towers, industrial boilers, chemical process water, and petroleum & steel plant cooling loops, constantly accumulate mineral microcrystals, suspended silt, corrosion sediments, and organic impurities during long-term operation. These tiny particles easily agglomerate, settle, and adhere to pipe walls and heat
Industrial circulating water systems, central HVAC cooling systems, industrial boilers, and metal pipeline networks face continuous threats of electrochemical corrosion, rust oxidation, scale deposition, and pipeline aging. After routine descaling and cleaning, bare metal surfaces lose protective layers and become extremely active, easily reacting with oxygen, moisture, and mineral ions
A well-balanced HVAC ventilation system relies on precise airflow distribution rather than simple air supply and exhaust. Uneven air volume, unbalanced wind pressure, excessive airflow in partial zones, and insufficient ventilation in remote areas are common problems in commercial buildings, industrial workshops, and central air conditioning systems. These issues lead
