PROMEOS® GLASS COOLING AND ANNEALING SYSTEM
The promeos® Glass Cooling and Annealing System is individually engineered for continuous glass production.
When hot glass moves from forming or heat-treatment zones into areas with significantly lower temperatures, uncontrolled cooling can cause thermal stresses, cracks and product losses.
promeos® solves this challenge with controlled, flameless heat inside or around the conveyor tunnel. This stabilizes the cooling curve and ensures a predictable thermal process.
HOW IT WORKS
The system applies controlled, flameless heat along the conveyor tunnel to precisely control the glass temperature profile as it transitions from forming temperatures to the required downstream process temperature.
This reduces the risk of thermal shock that can lead to cracking. Depending on the tunnel design, heat transfer is achieved by radiation, convection or a combination of both.
Different production processes require tailored integration concepts.
To meet different production requirements, promeos® offers both stationary systems for fixed production positions and movable modules that can be repositioned along the conveyor tunnel as process requirements change.
The system is suitable for container glass, tableware glass and new production lines, as well as retrofit projects requiring improved thermal control in existing cooling or annealing sections.

Why It’s Important
Excessive Cooling Can Cause Glass Cracking
Transporting glass from high forming temperatures to significantly lower downstream temperatures without controlled heat transfer creates internal thermal stresses.
The result can be cracks, breakage and scrap. Controlled heat inside the tunnel maintains a stable cooling curve.
