Energy optimization and climate comfort in production facilities: the Nord Legno case study with SIRE air curtains

Ensuring thermal comfort, energy efficiency, and operational continuity within a production environment is a complex challenge, especially in facilities with frequent access gates. This is the case for Nord Legno Srl , a Veneto-based company with over forty years of experience in the production and distribution of wooden pallets and packaging, which chose SIRE to optimize the climate management of its industrial spaces.

The result is a plant design in which Indesse industrial air curtain technology has been perfectly integrated with the existing heating system, improving internal comfort and significantly reducing energy consumption.

The need: efficiency and comfort in a high-traffic industrial environment

In manufacturing and logistics environments, the need to keep doors frequently open for loading and unloading generates significant heat loss. During the winter, warm air quickly escapes to the outside, while in the summer months, the opposite occurs, increasing the internal heat load and worsening working conditions.

For Nord Legno , this situation posed a dual problem: on the one hand, rising air conditioning costs, and on the other, suboptimal thermal comfort for production and logistics staff. The goal was therefore twofold: to reduce energy consumption and ensure a stable and comfortable microclimate within the departments.

The SIRE solution: Indesse industrial air curtains

To meet this challenge, SIRE proposed the installation of industrial air curtains from the Indesse series , equipped with the Comfort Superior control system.
These units generate a real "invisible barrier" of air that separates the internal environment from the external one, preventing direct exchange between the two air masses and thus reducing heat loss.

After an initial pilot installation, the solution was extended to all the plant's entrances , thanks to the positive results observed both in terms of energy efficiency and comfort perceived by operators.

Among the main features of the system:

• High performance airflow , calibrated to ensure effective separation even in large openings;
• Advanced electronic control , which allows automatic regulation of air speed and temperature according to environmental conditions;
• Master-Slave management , for centralized and coordinated control of multiple units;
• Compatibility with existing heating systems , allowing efficient integration with the cogeneration plant already present in the company.

Concrete results: reduced consumption and environmental well-being

The introduction of SIRE barriers has made it possible to significantly reduce heat dispersion and improve the stability of the internal temperature , even with the doors open.
This translates into reduced energy consumption and more efficient management of the heating system, which is no longer forced to continuously compensate for heat losses.

In addition to energy savings, the benefits have extended to the well-being of the operators: the reduction of air currents and the maintenance of a more constant microclimate have improved the quality of the working environment, with a positive impact on productivity as well.

Added to these advantages is improved indoor air quality , as the barriers reduce the entry of dust, insects and impurities from outside.

An integrated approach to energy management

The project created by SIRE for Nord Legno highlights the importance of an integrated approach to energy management.
The efficiency of a plant depends not only on the performance of individual machines, but on the ability to coordinate the various systems – heating, ventilation, cogeneration, and access control – into a single, optimized ecosystem.

Thanks to the flexibility of SIRE systems, the system can now be monitored and managed centrally, allowing for rapid intervention on the settings and maintaining constant efficiency over time .

Efficiency, sustainability and business continuity

The Nord Legno case represents a concrete example of how industrial air curtains can contribute to achieving environmental sustainability and production process optimization goals.

Reducing heat loss means cutting indirect CO₂ emissions , improving energy cost management, and creating healthier, more comfortable work environments.
In contexts where internal logistics are continuous and dynamic, these solutions prove to be a long-term strategic investment.

SIRE Technology: A Concrete Response to the Energy Challenge

With the project carried out at Nord Legno, SIRE confirms its ability to offer customized solutions for energy efficiency and climate comfort in industrial environments.
The use of Indesse air curtains represents a concrete response to the sustainability, comfort, and operational continuity needs of companies looking to the future with an integrated vision of energy management.
