DC Inverter DX Condensing Heat Recovery Air Handling Unit

The Holtop HFM series DX outdoor unit includes both DC inverter and fixed frequency types. The cooling capacity of the DC inverter unit ranges from 10 to 20P, while the fixed frequency unit spans from 5 to 60P. Building on the fixed frequency unit, the newly developed DX inverter unit incorporates enhanced vapor injection refrigerant technology to ensure superior heating performance under low ambient temperature conditions. The advanced air-conditioning system design and self-developed controller further enhance its efficiency and reliability.

Features of Indoor Unit

Heat Recovery Technology

With Holtop's core heat recovery technology, the cooling and heating loads from ventilation are effectively reduced, ensuring both energy efficiency and environmental protection.

Healthy Breathing

It blocks harmful substances such as indoor/outdoor dust, particulate matter, formaldehyde, and odors, allowing you to enjoy nature and breathe healthier air.

Comfortable Ventilation

Our goal is to bring you the comfortable and clean air.

Air Handling Unit Design

HEAT EXCHANGER

PM2.5 SOLUTION

Equipped with high-efficiency filtration filters, it effectively removes PM2.5 particles from the air, ensuring clean indoor air quality.

CONSTANT TEMPERATURE AND HUMIDITY

Precisely control outlet air condition, with tolerance within ±2°C ,and ±5% on humidity

INDOOR FORMALDEHYDE REMOVAL SOLUTION

The indoor unit can be optionally equipped with a formaldehyde removal module, which effectively filters and decomposes formaldehyde molecules. Combined with fresh air replacement and dilution, it provides double protection against formaldehyde.

Features of Outdoor Unit

Heat exchange

Multiple leading technologies combine to create a stronger, more stable, and efficient cooling system.

Silence operation

Innovative noise control technology, minimizing the operation noise for both indoor and outdoor unit, creating a silent environment.

Compact design

New casing design with better stability and appearance. The inner refrigerant components is from world famous brands to ensure high quality.

NEWLY DEVELOPED U-SHAPED HEAT EXCHANGER

Drawing on years of experience in outdoor unit development, manufacturing, and user feedback, Holtop has developed a new generation of U-shaped heat exchangers with three-sided heat exchange. As the core component of the refrigeration system, the performance of the heat exchanger directly influences the reliability and energy efficiency of the air conditioning system.

HIGH-EFFICIENCY REFRIGERANT HEAT EXCHANGE FLOW PATH

The high-efficiency 2in1 refrigerant confluence technology reduces the space occupied by the liquid-phase refrigerant on the heat transfer pipeline, and at the same time increases the degree of subcooling, making the long connecting pipe more efficient.
