Air curtains are widely used across the industrial sector — for warehouse doors, ovens, continuous dryers, or for air sealing and climate control when a heating module is included. They also help contain odours within production areas and prevent the loss of clean, conditioned air. Air curtains are an effective solution for odour confinement in food processing plants or waste management facilities, where it is essential that odours remain contained within designated zones.
In waste management plants in particular, air curtains play a key role in operations, allowing transport access doors to remain open while keeping them sealed to stop odours escaping to the outside environment.
Bluer Medio Ambiente — manufacturers of RTOs, thermal treatment systems, biogas flares, and other purification technologies — offers the BLUECOR direct gas air curtain system. It is composed of three main modules:
- Heating module (optional): a direct‑gas combustion system within the airstream that automatically adjusts air temperature according to the selected operating modes.
- Impulsion module: a fan that introduces warm or cool air as required, into the diffuser, controlled by a variable‑speed drive.
- Diffuser module: ensures stabilisation and uniform distribution of airflow, maintaining consistent air velocity and temperature across the entire coverage area.
With dedicated software, the system can be configured and fine‑tuned to meet specific client requirements, ensuring uniform and regulated airflow along the doorway. It fully complies with the most stringent air curtain standards currently in force in the food industry.
Real‑world application example:
An air curtain was installed at the automatic door of a food manufacturing facility, designed both to contain odours and to prevent insects from entering.

The door measured 3 metres wide by 3.15 metres high. Air velocity was controlled using the built‑in speed regulator, allowing compliance with the industry’s highest standards for food sector air curtains.
In this specific facility, the curtain’s integrated combustion module also provided optimal climate control, maintaining a comfortable indoor temperature during the winter months.
In summary, air curtains are a valuable complement for automatic doors or those that remain open for extended periods due to frequent vehicle movement. They enable environmental separation, effective odour confinement, and reduced energy losses in industrial buildings.
