We are based on 35 years experience in heat treatment of the glass. Until this year, we have produced more than 150 lehrs.


A Glass annealing lehr is a part of the production process needed for the manufacture of packaging, ovenware, decorative and possibly other kinds of glass. The lehr ensures controlled cooling of glassware that eliminates inner material tension.

The lehr is equipped with direct gas heating and a system of maximum/ minimum/off and by proportionally controlled cooling, or with an on - off system. Electrical heating can be supplied as an alternative.

The lehr is produced in belt width 800 ÷ 4500 mm.





in a company with more than 60 years of tradition in engineering production, specialized not only in the supply of machines for the glass and bakery industry, but also in the custom production of parts and entire machines according to customer documentation.
