1. PURPOSE OF THE DEVICE
Ostro air curtains are designed for use in regions with moderate or cold climates in spaces where the temperature range is -10C to
+40C, in conditions that are free from external contaminants such as pollen and hydrometeor (horizontal precipitation). In winter air
curtains protect against heat loss in rooms by directing a warm air stream across door ways preventing cold air from entering the
heated space. In summer, the air curtains can be used as cooling devices to prevent the entry of hot air and pollutants from the
outside.
The air curtains are designed to protect against heat losses
in buildings of medium and high capacity and with a required
mounting height is of 4 m such as:
supermarkets, large retail space,
car showrooms and service stations,
sports and show halls,
exhibition surfaces
