Air Curtains

In heated facilities, when external doors are opened, a large amount of cold air enters.
This creates several problems, including high energy waste due to the drop in temperature within work areas, and subsequent harmful effects on operators’ health (colds and respiratory illnesses).

The experience of Officine Termotecniche Fraccaro, gained over more than 60 years in the field of high energy-saving industrial heating systems, has led to the design of DEFENDER air curtains, suitable for solving all problems caused by door openings in heated or air-conditioned buildings.

Advantages

• Energy saving
• Eliminates heat loss to the outside caused by opening doors
• Prevents heat escape and energy waste by avoiding thermal shocks that negatively affect people's health
• Uses the air present in the upper part of the room (already warm), channeling it downwards
• Single-phase 230Vac electric motor, 3 speeds
• Wide range of models, versions, accessories, and solutions:
BA-A: air-only versions
BA-E: versions with electric heater (230Vac and 400Vac)
ATR-BAR: versions with water coil
• Adjustable bracket to allow for a variety of different inclinations depending on the characteristics of the door
• By placing multiple units side by side, doors of any width can be equipped

These are the most effective and efficient for maintaining internal temperature. They require a reinforced concrete distribution channel, to be constructed during flooring work.

Additionally, air curtains that do not require construction work are available with LATERAL or VERTICAL flow; see the brochure for more information.
