Direct Expansion Air Handling Unit
Combined type DX AHU

The HMZK-D Series DX Modular Air Handling Unit consists of a modular air processing section connected to an independent cooling source via copper piping. It is available in various configurations, including cooling-only, heat pump, purification, temperature and humidity control, and full fresh air models. Additionally, the air processing section can be further customized to meet specific industrial process requirements, ensuring optimal performance for a wide range of specialized air treatment applications.

Energy Efficiency
Integrated with its own cooling and heating source, air treatment, and automatic control functions, this system ensures simple operation, reduced intermediate heat exchange losses, and high operational efficiency.

Space-Saving
Designed with decentralized air distribution, eliminating the need for a dedicated central air conditioning machine room, thereby saving valuable space resources.

Easy Maintenance
Each air conditioning system operates independently, allowing separate maintenance without affecting the normal operation of other systems.

Low Initial Investment
The indoor unit connects directly via copper piping, eliminating the need for chillers, cooling towers, chilled water pumps, and complex piping systems. The simplified control system allows for phased construction, reducing overall engineering costs.

Convenient Installation
Simply connect to a power supply, and the system is ready for use.

Important Maintenance Notes

✔ Ensure the heat exchanger is free of frost before operation.
✔ Drain residual water from the coil before winter to prevent freezing.
✔ When using electric heating, make sure the fan is running before activating the heater. It is recommended to turn off the heater and steam valve at least 5 minutes before stopping the fan. Overheat protection should be integrated into the power circuit.
✔ Regularly inspect electrical wiring and terminals for looseness or aging. Replace damaged wires immediately.
✔ Use a four-core power cable for the unit’s power supply, ensuring a reliable grounding connection.
