| The heated air is evenly distributed throughout the chamber by means of a ductwork distribution system linked to a Primary Fan ‘down stream’ of the heat source. In this way the heated air is thoroughly pre-mixed with recirculation air from the chamber to minimise the temperature differential of the two airflows before re-entry into the chamber. A manually operated butterfly-balancing damper is fitted to each of the supply ducts into the chamber to ensure evenly heated air distribution throughout the system.
Recirculation air is then drawn from the chamber to be re-heated to the desired supply temperature before re-entry. |
