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.
Advanced silencing technology, More quiet and reliable operation
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.
