BOC Booster is designed for both temperature controlled and mixing ventilation. The rooms are normally supplied with under tempered air. When heating is required the supply air temperature is increased and the BOC is switched to Booster level, and the warm air is pressed down into the room by the Booster nozzles.

Technical description

Design

BOC is designed for rooms with high ceilings such as industrial premises, large shops, sports halls etc. It features an octagonal shape, where the top section is fitted with Swegon’s nozzles. The top section is used to supply hot air.

The lower section has a perforated, removable front cover. Inside this there is a distribution plate which is equipped with flexible distribution system, Varizon®.

The nozzle section and the perforated section are separated by a damper function. This is controlled by means of an electric motor (1) or manual control (2).

BOC is mounted to a wall or pillar using the brackets supplied with the terminal.

Material and surface treatment

BOC is manufactured in galvanized sheet steel. The air diffuser’s nozzles and VARIZON distribution discs are made of plastic (PP Polypropylene). The whole terminal unit is powder painted.
