Product Details


Air Handler AHU DX coil Air Handling Unit Direct Expansion Coil
Combined with core technology of HOLTOP AHU, DX (Direct Expansion) coil AHU provide both AHU and outdoor condensing unit. It’s an flexible and simple solution for all building area, such as mall, office,Cinema,School etc.
Compared with other centralized and semi-centralized air handling systems, the DX Coil Air Handling system layout is simpler and more flexible, so it is widely used in shopping malls, office buildings, apartments, theaters, schools and other places.
| Long piping design The pipe connection length between indoor unit and outdoor unit can reach 50m, and the maximum drop can reach 25m. The indoor unit and outdoor unit can be installed on site more flexibly. |


Efficient refrigerant heat exchange flow path
Efficient two-in-one refrigerant confluence technology improves the liquid phase flow rate of the refrigerant, improves the overall heat transfer coefficient of the heat exchanger, and improves supercooling and strengthens the refrigerant transmission distance.


High efficient heat exchange fins
The innovative high-efficiency low-pressure loss window fins are made of hydrophilic membrane aluminum, which can improve the heat transfer wet film heat transfer coefficient and improve the overall heat exchange performance of the unit.


Comfort Control System
The wire controller is simple and convenient, flexible in application, and widely used in small and medium-s


Functional control system
Building systems based on the MODBUS protocol can be directly connected to the centralized control system through the MODBUS communication interface standard on the unit, no need to access conversion equipment, and are suitable for large and mediumsized air-conditioning locations.
Dual Temperature Sensors
Innovative design with two temperature sensors, one at return vent, and one at the control panel, to detect the indoor temperature around the room, and make sure the hot wind(winter heating mode) would be sent to each corner of the room uniformly.


Control network topology diagram
Advanced silencing technology, More quiet and reliable operation


High efficient heat exchanger
| New U-shaped heat exchanger As the core element of the refrigeration system, the heat exchanger directly determines whether the air conditioning system is reliable and energy-saving. | U-shaped heat exchanger structure The copper tube adopts φ7.94 thread copper tube, the flow rate is moderate, and the comprehensive performance of heat exchange defrosting is optimal. |
Green Refrigerant
The Holtop HFM series SUSPENDED DX AIR HANDLING UNIT uses R410A as refrigerant, with zero ODP, to avoid damage to the ozone layer and at the same time, greatly improve cooling capacity.
Easy maintenance
The whole unit uses frameless foaming boards to construct, and self-tapping screws to connect these boards, making it very easy to be disassembled for maintenance.
High ESP Design – Easy Selection
The indoor unit generates a high ESP, making it possible to cover the whole area to avoid uneven distribution of temperature. Such feature makes solution and design much easier.
Wide Operation Temperature Range
Even at 15°C, the cooling function can be activated normally; Heating function can be activated at -10°C in
Both return air and fresh air indoor units available
The HFM outdoor unit can work with both return air and fresh air Indoor unit, to meet different customers’ need
