The tin cooler of Type HTICO 600 operates on the physical principle of convection cooling. It is installed directly on the side walls of the tin bath. The cooling pipe is submerged directly into the liquid tin. The tin cooler extracts heat from the tin so that the tin, in turn, could extract heat from the glass ribbon.

The tin cooler consists of a functional sealing box, a cooling pipe with a flow monitor and a jackscrew for adjusting the immersion depth of the cooling pipe. Depending on the type, the immersion depth can be adjusted by means of a motor or a crank.
