Holtop HZN-30 and HFM-30HB1-DC DX Coil Air Handling Units (AHU) integrate multiple leading technologies to deliver a more powerful, stable and energy-efficient cooling system. Innovative noise-reduction technology minimizes operating noise from both indoor and outdoor units, creating a quieter environment. The newly designed shell improves structural stability and appearance.
The Holtop DC DX Air Handling Unit range comprises two series: the DC Inverter DX air conditioner outdoor unit and the constant frequency DX air conditioner outdoor unit.

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