The exit end cooler of Type HEECO, which is installed in the narrow part of the tin bath, serves to cool down the glass ribbon to the optimal lift-out temperature (approx. 610 °C), which is crucial for ensuring smooth production.

The exit end cooler is moved by means of a motor-driven carriage on two rails, so the cooling element can easily be moved into and out of the tin bath. The travel distance on the rails is supervised by several limit switches and is limited on either end by mechanical stops.

The cooling element of the cooler is pushed laterally into the tin bath through a functional sealing box. The cooling element is positioned above the glass ribbon. Due to the precisely adjustable insertion and retraction of the cooling element, the glass ribbon temperature required for the dross box and the annealing lehr can be attained in the most efficient way.

The cooler can be operated via a panel directly at the cooler or remotely from the control room. This facilitates fast and uncomplicated control of the glass ribbon temperature.
