Glass Duct Heating During Saint-Gobain Shutdown Maintenance

We’re excited to announce that Heatmasters has successfully participated in a shutdown maintenance project together with Saint-Gobain, at their production facilities in Hyvinkää, Finland!

Heatmasters provided heating for a glass duct, while maintenance activities took place at a glass-melting furnace.

During the project, we utilized four Heatmasters’ 500 kW gas burners, controlled with our legendary Rigel26 digital controllers. Heatmasters gas burners were running non-stop throughout the 6-week project. This was important, as the glass duct had to be kept at a constant temperature of 1000 °C for the entire duration, to be able to start up production immediately after maintenance activities were completed.

In glass manufacturing, the “glass duct” or “glass furnace flue” is crucial for transporting molten glass between stages of processing. Maintaining a high temperature in this duct is crucial to prevent the glass from cooling and solidifying before it reaches its intended destination.

A huge thank you to our team for their hard work and to the Hyvinkää factory personnel for their cooperation!
