Upgrade your facility with high-efficiency DX technology delivering faster installation, lower energy consumption, and reliable year-round climate performance.
Direct Expansion (DX) Units are special air conditioning systems that cool air directly. The unit integrates air filtration, temperature reduction, dehumidification, heating, and humidification functions. Unlike other systems, they don't need water pipes or cooling towers. Instead, these smart machines use refrigerant to cool air right away.
As a leading Direct Expansion (DX) Units Manufacturer, SongXin makes these systems for buildings of all sizes. From small offices to huge factories, these units work everywhere.
Understanding how these systems work is simple. Every Direct Expansion (DX) Units system has two main parts:
