JiangNan supplies cold room air curtains for chiller room entrances, processing room doors, packing areas, and cold storage traffic points. An air curtain helps reduce warm air entry when a door is opened frequently, but it should be selected and installed according to door height, width, room temperature, traffic, and site airflow.
Air curtains are most useful where people, carts, or light product movement create frequent short openings. They are not a substitute for a well-sealed cold room door.

Engineering Scope
- Air curtain selection by door width and installation height.
- Voltage and frequency confirmation for export markets.
- Door traffic and opening frequency review.
- Coordination with sliding doors, hinged doors, or strip curtains.
- Installation position and power supply planning.
- Export packing and accessory listing.
Application in Cold Rooms
Air curtains are commonly used at processing room doors, chilled storage entrances, preparation areas, and logistics passages. They help reduce air exchange during frequent door opening and can improve comfort around the doorway.
For freezer rooms, air curtains must be reviewed carefully because very low temperature, frost, and condensation can affect performance. In many freezer projects, a proper freezer door and traffic control remain more important.
Engineering Review Method
JiangNan reviews air curtain use by door size, installation height, room temperature, traffic frequency, ambient temperature, doorway airflow, voltage, and hygiene requirement. An air curtain should be selected for the actual opening condition. A unit that is too weak will not cover the opening, while a poorly positioned unit may create noise or uncomfortable airflow without reducing warm air entry effectively.
The review also checks whether an air curtain is the right accessory. For some freezer rooms, a sliding freezer door, strip curtain, anteroom, or traffic discipline may provide better results. JiangNan treats the air curtain as part of the entrance design, not as a universal solution.
Ambient Temperature Consideration
In hot climates such as Saudi Arabia, warm air entry through door openings can quickly increase heat load. An air curtain can help at suitable entrances, but door sealing, opening discipline, and refrigeration capacity still need proper design.
Panel and Door Coordination
The air curtain should match the door opening width and mounting structure. Oversized openings may need multiple units or a different entrance design. The panel wall or door frame should provide a stable mounting position.
Door Recommendation
Use an air curtain together with a proper cold room door. For frequent pallet traffic, a sliding door may be used with a strip curtain or air curtain depending on the operating temperature and hygiene requirement.
Airflow Coverage and Mounting Position
Airflow should cover the full doorway. The air curtain should be mounted close to the opening and aligned so the air stream is not blocked by beams, door tracks, lights, or ceiling panels. If the opening is wide, several units or another entrance design may be reviewed.
Mounting structure matters. The panel wall or frame should support the equipment safely, and service access should remain available for cleaning or inspection. JiangNan checks installation height and door width before recommending the arrangement.
Refrigeration System Notes
Door opening load affects refrigeration selection. If an air curtain is added because traffic is frequent, the refrigeration load calculation should still include door opening frequency and ambient temperature.
Use in Hot and Humid Areas
In hot climates, warm air entering the cold room brings heat and moisture. An air curtain can help reduce air exchange during short openings, but it cannot fully seal the room. Door closing behavior, gasket quality, and traffic management still matter.
In humid environments, condensation risk around the doorway should be reviewed. If air movement is poorly arranged, moisture can still collect around frames, floors, and nearby panels. JiangNan reviews air curtain use together with door sealing and refrigeration capacity.
Installation Considerations
The air curtain should be installed at the correct height and close to the doorway. Airflow should cover the opening without being blocked by beams, door tracks, or ceiling structures. Electrical supply and maintenance access should be confirmed before installation.
Common Mistakes to Avoid
Common mistakes include selecting only by door width, installing too high, allowing the air stream to be blocked by door hardware, using an air curtain as a replacement for an insulated door, and ignoring freezer frost conditions. Another issue is adding an air curtain without updating the refrigeration load review for frequent traffic.
JiangNan avoids these problems by reviewing the entrance as a complete system. Door, air curtain, strip curtain, room temperature, traffic, and refrigeration duty should work together.
Information Needed Before Final Design
Useful information includes door width, door height, installation height, room temperature, ambient temperature, traffic frequency, product movement method, voltage, and whether the room is chilled or frozen. Site photos are helpful when the doorway has beams, tracks, or limited mounting space.
Export Packing Support
Air curtain units and accessories are packed for export shipment. For full cold room projects, they can be included in the packing list with panels, doors, refrigeration equipment, and controls.

FAQ
Can an air curtain replace a cold room door?
No. It helps reduce air exchange during opening, but the cold room still needs a proper insulated door for sealing.
Is an air curtain suitable for freezer rooms?
It depends on the temperature and doorway condition. For low-temperature freezer rooms, frost and condensation must be reviewed carefully.
How is air curtain size selected?
Selection depends on door width, installation height, voltage, airflow requirement, and site condition.
Does an air curtain reduce refrigeration load?
It can reduce warm air entry at frequently opened doors, but refrigeration selection should still include door traffic and ambient temperature.
Can it be supplied with a cold room package?
Yes. JiangNan can include air curtains with panels, doors, refrigeration equipment, controls, and accessories.
