The Smith's Ostro range of commercial air curtains are designed for use in the entrances of shops, offices, leisure facilities, hotels, schools, hospitals and most other public buildings. Ostro is available in 3 versions - W Hydronic, E Electric and C Ambient.

Ostro air curtains are designed for use in regions with moderate or cold climates in spaces where the temperature range is -10 degrees to +40 degrees, in conditions that are free from external contaminants such as pollen and hydrometeor (horizontal precipitation).

In winter Ostro air curtains protect against heat loss in rooms by directing a warm air stream across doorways 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.

Available in hydronic versions (Ostro W) and electric versions (Ostro E), and ambient versions (Ostro C) without a heater for applications with entrances where no additional comfort heat is required.

There are 3 sizes, 1084mm, 1554mm and 2024mm available in all 3 versions.

Determining the right sort of Electric Heaters is a key decision. Once you determine that Convector Heaters give the right answer then the Smith's HPAC310016 is without doubt worth factoring in to your final decision.
