One-stream air-heating units АО 2 (water) and АО2-П (steam) are applied for air heating of industrial premises, which are not constantly attended by people (or have no fixed operating area) or are attended by people constantly, provided that the height of the premises makes up to 6 m, as well as for stand-by heating of industrial premises. Heating unit of АО2 type are designated for operation using such a heat-transfer agent as «hot water or superheated water with the temperature of 95-150 ° Сand complete usage of recirculation air for the territories with moderate climate «У» of the 3rdcategory of location as per GOST 15150-69.
Air-heating unit is hanged or installed on the brackets. During the operation of heating unit the air,supplied by a fan, is heated passing the calorifer and delivered to the premises. Air-heating units have high heat productivity and efficiency, ensured by an optimal distance between fan and calorifer, excluding dead zones while air flowing in the unit,as well as by application of high-quality calorifers and axial fans.
Heating units manufactured by «Concern Medved» haveprotective mesh, which protects electric motor from strokes and deformations, as well as prevents the unit from ingress of foreign objects. Forthe purpose of convenience there is a box for unit connecting to mains.
Heating units of АО2 type are manufactured in right-hand option – if to look at the unit from the side of an axial fan calorifer delivery pipes are located from the right side of the unit, and for left-hand one delivery pipes are located from the left side.
