Door width and height
Dimensions are essential, but wind, building pressure, temperature difference and opening duration also affect the selection.
Design and retrofit
When an industrial air curtain falls short of expectations
If cold draughts, temperature loss or uncontrolled airflow remain, output alone may not explain the result. Direction, controls and the airflow through the building should be reviewed together.
Request a doorway assessment
An industrial doorway is part of an airflow system
An industrial air curtain counters natural air movement at the opening. That movement is affected by temperature differences, wind, thermal buoyancy, extraction systems and other openings in the building.
For a retrofit, the first task is to identify the main airflow drivers. The review can then determine whether controls, direction, installation position or the overall system concept should be adjusted.
Technical guidance
Seven factors that influence performance
The same checks support both new projects and the assessment of an existing industrial air curtain.
Air volume, reach and momentum
A stable barrier depends on the combination of velocity, momentum, distribution and direction across the opening.
Wind and building pressure
Facade exposure, building height, roof openings, other doors and thermal buoyancy can influence airflow.
Extraction and supply air
Process extraction or negative pressure can draw additional outside air through the doorway.
Obstructions around the door
Guides, canopies, racks, impact protection and vehicle positions can affect installation and the air stream.
Controls and operating routine
Controls should reflect door position and operating conditions so the system runs when required.
Commissioning and verification
Direction and operating parameters should be checked and adjusted under representative conditions.
A practical four-step review
Document the current situation
Record photos, clear dimensions, opening times, operating complaints and relevant conditions.
Identify airflow drivers
Review wind, temperatures, building height, extraction, supply air and other openings.
Assess system and installation
Check configuration, airflow direction, output, controls, condition and available mounting space.
Prioritise the response
Optimise settings, adjust the installation or evaluate a purpose-engineered replacement where appropriate.
FAQ
Frequently asked questions
Why may an industrial air curtain deliver less effect than expected?
The configuration, reach or direction may not match the door and building airflow. Wind, negative pressure, other openings and control settings can also affect the result.
Can an existing air curtain be improved?
Depending on the installation, direction, operating stage, controls or shielding may be adjusted. First, the configuration should be checked against the opening and the intended result.
Is the most powerful air curtain automatically the best choice?
No. Output, distribution, direction and control need to work together. The appropriate configuration is the one designed for the actual doorway and operating conditions.

Which solution fits your industrial doorway?
A photo, doorway dimensions and a short description are enough for an initial technical assessment.
