The Cabinet Air Handling Unit (AHU) series is available in four models: HMDG, HMWG, HMLG, and HMSL. These units offer powerful cooling capacity, high efficiency, low noise, and long-lasting durability, making them an essential central air-conditioning terminal device for concealed spaces. They are widely used in luxury hotels, shopping malls, office buildings, hospitals, airports, subway stations, and exhibition centers, where high air volume, cooling efficiency, humidity control, and cleanliness are required.
Each model is available with 4-row, 6-row, or 8-row coil configurations and offers heat exchangers in 8, 10, or 12 fins per inch, providing a range of cooling capacities to meet different application needs.

Box Structure
- It adopts the box-board direct assembly structure, which has good heat insulation performance and no cold bridge trouble.
- Double-sided insulation board, inner and outer boards are available in a variety of materials. The standard is painted galvanized steel sheet, which has excellent anti-corrosion performance and high hardness. Optional zinc-aluminum co-plating plate. PE protective film is attached to the outer board to ensure that it is not damaged during processing and transportation.
- Rigid polyurethane thermal insulation material, one-time forming foaming process, the foaming material is tightly combined with the inner and outer boards, and the thermal insulation performance and structural strength are excellent.
Fan and motor
- The well-known brand double-inlet centrifugal fan, the impeller and frame are made of hot-dip galvanized steel plate, with high structural strength. Strict dynamic and static balance test, low noise and low vibration. The motor is a fully enclosed self-fan-cooled squirrel cage three-phase asynchronous motor with protection grade IP54 or IP55, class F insulation, standard power supply 380V/3P/50HZ.
- According to the customer’s air volume and pressure requirements, each machine is selected by computer one by one, and the efficiency, bearing life, noise, and other factors are comprehensively considered to ensure the best working conditions.
- It adopts a European-style taper pulley and has been tested for dynamic and static balance. It is flexible in disassembly and assembly and easy to maintain.
- The belt adopts a well-known brand, with high transmission power and wear resistance.
- The damping points of the spring damping are strictly selected and calculated, and the damping efficiency is more than 95%.
- The fan motor adopts an aluminum profile or channel steel base frame, beautiful appearance, and convenient belt adjustment.
Coil Heat Exchanger
The coil heat exchanger consists of hot and cold coils made from copper pipes with anti-corrosive and hydrophilic aluminum fins. These features enhance durability and improve heat transfer efficiency. Its low-speed mechanical tube expansion ensures a firm bond, while a flanged joint design prevents damage during transport. Available in 4-row, 6-row, and 8-row configurations, each coil is computer-selected for optimal performance. Anti-freezing measures, such as switches, drain-type protection, and downstream coil layout, ensure reliability in cold regions. Each unit undergoes rigorous leak testing (2.8 MPa test pressure, 1.6 MPa max working pressure), guaranteeing durability and efficiency.
