Ultra Low Noise
The unit operates with ultra-low noise, featuring a newly designed wide impeller with a large diameter and slow-speed forward multi-blade design. The fan casing is reinforced with ribs for added strength and equipped with NSK bearings to minimize vibration and noise during operation. It uses PEF heat insulating material and a one-step molded drain pan, providing durability and excellent thermal insulation. The 42CNA model complies with the new national standard GB/T19232-2003, with noise levels 3-5 dB lower than the standard requirements.

Optimized Fan Design
The fan impeller is designed for optimal airflow and is supported by NSK bearings, ensuring smooth and quiet operation.

Fresh Air Intake Design
To improve Indoor Air Quality (IAQ), the unit can be configured with fresh air intake equipment. This feature allows adjustable intake size to match fresh air flow requirements and is easy to assemble in the field.

Ultra Thin Profile
With a height of only 230 mm, the unit saves installation space and meets the requirements of various installation environments.

High Efficiency Heat Transfer
The coil uses a double-flanging structure with lanced blue fins and advanced mechanical tube-expanding technology. This ensures optimal contact between copper tubes and aluminum foil for superior heat exchange. The wide impeller creates an even air velocity environment, improving cooling capacity beyond similar two-row or three-row units.

Optional Accessories
Various drain pans are available for different application needs, providing good thermal insulation and watertightness. A large LCD temperature controller with remote and block contact control options is offered. The system supports four-pipe functions and motorized 2-way and 3-way valves for efficient energy use. A UV-C sterilizing lamp is also available as an option to ensure high air quality.
