Product Description
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.
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.
Holtop combined with many years of outdoor unit development experience and market demand, developed a new generation of U-shaped heat exchanger. Such advanced and efficient heat exchangers have made Holtop's HFM series highly efficient and energy-saving, and also meeting the Holtop Vision of "making air treatment more healthy and energy-saving".
The airflow of the fan is effectively used, and the heat exchange area is fully expanded without increasing the space of the unit, and the heat exchange efficiency is greatly improved.
Compact structure, high strength, more convenient for installation and maintenance.
The use of hydrophilic membrane aluminum fins improves the heat transfer wet film heat transfer coefficient and provides the overall heat transfer coefficient of the unit.
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.
The distance between φ7 copper tubes is the smallest, the frost has a great influence on the heat transfer, and the frost layer is thick, which affects thedefrosting time.
The diameter of φ9.52 is large, the disturbance to the heat transfer boundary layer is small, and the heat transfer efficiency is low.
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.
