Choose from cross-flow total heat exchangers, cross-flow plate heat exchangers, or rotary heat exchangers to meet different customer requirements.
Equipped with a high-efficiency filter element, the unit effectively removes PM2.5 particles carried in the air, ensuring that outdoor air entering the indoor space is clean.
The indoor unit can be equipped with a formaldehyde removal module to effectively filter and decompose formaldehyde molecules. Combined with the replacement and dilution provided by heat exchangers and filters, this achieves double formaldehyde removal.
With this AHU, fresh outdoor air is brought into the room. By increasing oxygen concentration, reducing carbon dioxide, and removing odors and other harmful gases, indoor air quality is greatly improved.
