Multiple heat exchanger options are available — including cross-flow total heat exchangers, cross-flow plate heat exchangers, and rotary heat exchangers — to meet diverse customer requirements across different ventilation and energy recovery applications.
High-efficiency filter elements effectively remove PM2.5 particles from incoming air, ensuring clean outdoor air enters indoor spaces.
An optional formaldehyde removal module effectively filters and decomposes formaldehyde molecules, complemented by heat exchanger and filter replacement for dual formaldehyde removal.
The AHU brings fresh outdoor air into rooms, increasing oxygen concentration while reducing carbon dioxide and removing odors and harmful gases for significantly improved indoor air quality.
