The tin bath bottom cooling is an industrial product which has been constructed and produced for industrial use and operation only. The tin bath bottom cooling is divided in float bath sections, so-called bays, and serves for the cooling of the lower surface of the bottom wall. The cooling is carried out through air supply by means of fans connected with the pipe. A row of nozzles is arranged under  each float batch section (bay), which can be adjusted to the cooling capacity by means of a throttle valve.

The fans provide cooling air for the cooling of the bath bottom. They are located in the fan room above the concrete duct, which serves as air supply duct. There are only two fans constantly in operating mode, the third one is reserve. The fans must be connected by a respectively trained specialist only.

In the channel duct, after the fans, a pressure transmitter is built in in each case, which serves for monitoring of the fan operation. The pressure transmitters must be connected by a respectively trained specialist only.

A pressure monitor, which monitors the pressure in the pipe, is inserted  in the distribution  feeders bay 0, bay 8 and bay 13. The pressure monitor must be connected by a respectively trained specialist only.

A pressure gauge, which serves for the indication of the pressure in the pipe, is built into the distribution feeders bay 0, bay 8 and bay 13. The pressure gauge must be connected by a respectively trained specialist only.
