The air curtain COR-3.5-1000 N from Soler & Palau, reference 5226631900, is a thermal barrier system designed for installation at commercial premises entrances or public interior spaces. It provides a controlled air stream that thermally separates the indoor environment from the outside, preventing heat or cold loss and reducing energy consumption in air conditioning.

This model incorporates an electric heating system with a heating power of 3.5 kW, making it ideal for providing thermal comfort in frequent passage areas. It is suitable for installations up to 3 m in height and features three operating speeds to adapt to different flow and temperature needs. Additionally, its compact design and white RAL 9003 finish make it visually discreet and integrable into any environment.

The curtain can operate in both cold and hot modes (C/H) and includes a built-in remote speed selector, facilitating configuration from the installation point. It is also equipped with a thermal safety fuse and allows connection with an external room thermostat for greater precision in comfort management.
