Core Features


Corrosion-Resistant Metal Casing

Crafted with a full metal body, the air curtain offers exceptional corrosion resistance, making it suitable for long-term use in various commercial environments. The elegant, luxurious design complements modern architectural styles, adding both functionality and aesthetic appeal. This durable air curtain withstands daily wear and tear, ensuring reliable performance for years.


Multi-Layer Heat Dissipation Coil

Equipped with a multi-layer compound fan coil, the product delivers efficient heat dissipation using hot or cold water. The coil design maximizes heat transfer, ensuring rapid temperature rise and consistent warmth throughout the space. This high-efficiency air curtain minimizes energy consumption while providing powerful heating.


Dual-Water Inlet Design

The water warm air curtain features preset left and right water inlets, offering flexibility for different installation scenarios. This humanized design allows installers to choose the most convenient inlet based on the space’s plumbing layout, simplifying setup and ensuring optimal performance.

This flexibility allows for easy adjustment of heating and airflow based on specific needs, whether heating a crowded restaurant or maintaining a comfortable temperature in an office lobby. The user-friendly air curtain ensures convenient operation for staff.


Year-Round Versatility

Designed for year-round use, the air curtain functions as a heating solution in winter and an air barrier in summer. In warmer months, it blocks hot outdoor air and preserves cool indoor temperatures, while the condensate water collection plate prevents moisture buildup, making it suitable for seasonal switching.
