The Function of Revolving Door Air Curtain

In the hot summer, outdoor high temperatures can affect indoor temperatures, and the air curtain can effectively block hot air from entering, keeping the interior cool.

In the cold winter, outdoor low temperatures can significantly impact indoor temperatures, and the air curtain machine (heated air curtain machine) can generate warm air to block cold air from entering, maintaining a warm indoor environment.

This temperature control not only makes customers feel more comfortable but also enhances the operational efficiency and service quality of the restaurant.

The Color of Revolving Door Air Curtain

At the same time, the revolving door air curtain machine can be customized according to the color of the customer’s revolving door. Such as RAL9002, Whether it’s the metallic silver, industrial black, or warm wood grain texture, we can choose the appropriate color for painting according to customer requirements, ensuring that the air curtain machine seamlessly integrates with the revolving door.
