CNUD EFCO GFT applications

Everything to do with float glass: That’s our line.

Passion becomes experience: CNUD and Grenzebach have helped make the industrial float glass process a success story from the very beginning; EFCO has added its experience with the tin bath roof. The result is enormous process knowledge that benefits you in all production steps.
Integrated solutions

Glass is magic. We help make it happen.

From the tin bath to the annealing lehr to the cold end and the transport of the finished product to the warehouse: now you get everything from one source. This means uniform control concepts, fewer interfaces, more synergies, and fewer coordination efforts – whether you need the complete package or solutions for specific stages.

Your plant does the work, SERICY does the thinking.

Digital solutions that really make a difference: SERICY, Grenzebach’s digitalization platform, is the control center for the factory of the future. Cold end data can be linked to upstream information, and insights can be used directly for optimization – all based on CNUD EFCO GFT’s excellent process knowledge.
Climate protection and sustainability

Waste is a thing of the past. Aim for the future.

Responsible resource use, reduction of energy consumption and the lowest possible emissions: these are what companies in the glass industry are increasingly being judged by. The experts from Grenzebach and CNUD EFCO GFT provide effective solutions in this area and jointly drive forward the development of energy-efficient technology.
