5. The tempering glass line and Heat-Soak-Test-Oven

a. The tempering glass line
The tempering glass line consists of a modern furnace and loading and unloading conveyors.
+ The furnace can temper the maximal glass size (2900 x 5200 mm).
+ The glass is heated by High air volume Glaston Chinook™ convection system which leads to optimise heat uniformity and help to avoid hot spots in the glass. Consequently, the tempered glass has higher strength and durability than other normally annealed glass.

b. The Heat-Soak-Test-Oven

The oven of SADO GROUP uses the most advanced technology and it is manufactured by Torganuer Maschinenbau company. The oven stringently tests tempered glass and destructs all unqualified glass in order to prevent glass from a spontaneous breakage.

1. Fine Water Filtration System

SADO GROUP installed Fine Water Filtration System of EUROWATER (Germany) to provide high purity water for processing glass. Filtration process comprises water softening and Reverse Osmosis (RO – without using chemicals). This is the most modern water treatment system which is capable of removing pyrogenic substances as well as microorganisms. Washing glass with filtered water provides the best output. Therefore, physical features, colors and clearness of the glass are not changed when tempering. The system which consists of technical know-how and selected high-quality components complies with the highest industrial standards.

2. The system of recirculated water treatment

In order to protect the environment and provide clean water for processing glass, SADO GROUP installed a system of recirculated water treatment manufactured by LiSEC Corporation. Before dirty water is conveyed into the cleaning system, a flocculant is added continuously and automatically which is then mixed with dirty water using an integrated mixer. The lamellar package integrated in the cleaning system ensures a short reaction time with minimum water losses. The system filters all of glass particles in dirty water. The glass particles are solid and harmless waste which is kept in safe tanks. Then they are reused as the raw material for float glass manufacturers to save natural resources. SADO GROUP always pays special attention to saving materials and reusing natural resources. For this reason, we can prove that our factory is friendly to environment and contributes to develop "green architecture".
