1.5 Meter Centrifugal Hot Water Type Air Curtain

      The air curtain machine generates a powerful airflow through the motor driving the cross-flow or centrifugal fan wheel, creating an "invisible door curtain." It divides indoor and outdoor areas into two independent temperature zones, creating a comfortable indoor environment, maintaining indoor air conditioning and purifying indoor air. While saving electricity, it also facilitates air circulation, effectively isolating dust, smoke, odors, insects, and microorganisms. It prevents the outflow of cold (warm) air, saving electricity and effectively preventing cold (warm) air leakage. By dividing indoor and outdoor areas into two independent temperature zones, it assists in circulating and regulating temperature during prolonged operation of air conditioners, achieving the goals of energy conservation and environmental improvement, as well as providing dust and insect prevention effects.
Insulation Function
Air curtain machines are mainly used in places like restaurants and shops where customers frequently enter and exit, requiring constant door opening and closing. This can maintain indoor cold or warm air temperature with 60-80% efficiency, allowing only minimal temperature changes.

Insect Prevention Function
It can be observed that most annoying and harmful insects cannot pass through the air curtain wall. This makes it easier and more effective to maintain hygiene in places such as fruit counters and fast-food restaurants.

Heating Function
Air curtain machines also include electric heating air curtains, typically using PTC heating. There are also hot water air curtain machines. Both types can increase the temperature at entrances and exits, with temperature increases ranging from 30 to 60 degrees, commonly used in northern regions.

Dust Prevention Function
If installed in the lobbies of machinery factories or food and clothing stores facing bus lanes, air curtain machines can effectively isolate external dust, maintaining cleanliness at a 60-80% level.
