ENERGY-SAVING solutions FOR GLASS TEMPERING 

Tempering is one of the most important processes in a glass processing factory. It is the only way to increase the safety, strength and durability of the end product. At the same time, this process requires a lot of energy. After all, glass needs to be heated up to +600 °C and then cooled down back to room temperature.

Therefore, when looking for ways to save energy in a glass processing factory, a tempering line often offers the most significant potential. 

MODERN HEATING TECHNOLOGY TO SAVE ENERGY

VORTEX PRO CONVECTION

The Glaston Vortex Pro convection upgrade is one of the easiest and most cost-efficient ways to improve the productivity and energy efficiency of your RC tempering line.

ROLLER HEAT CONTROL (RHC) TECHNOLOGY

Roller Heat Control technology automatically controls roller heat using an accurate measurement system. 

  • Roller heat information is transmitted to the furnace control system, which automatically adjusts the bottom heat levels to balance roller temperatures
  • Better heat control increases glass quality, increases yield and minimizes energy costs
  • Available as an option for new Glaston tempering lines and as an upgrade for existing tempering lines

HEATING CHAMBER REPLACEMENTS 

The Glaston FC- and RC-zones heating chamber upgrade – with the latest Insight iControL automation system – is designed to be a quick and cost-efficient modification for your existing tempering line.

MODERN COOLING TECHNOLOGY TO SAVE ENERGY

QUENCH ENERGY OPTIMIZATION

1. Quench Energy Optimization for new machines

Quench Energy Optimization reduces energy consumption by optimizing the quenching and cooling area based on loading length.

2. Quench Energy Optimization for existing machines

The UPG Quench Energy Optimization reduces energy consumption by optimizing the high-pressure flow during the quench cycle.

ENERGY-SAVING IMPELLER

Modernizing the blower impeller effectively saves energy. 

  • The carbon fiber impeller structure withstands higher accelerations and decelerations than a comparable steel impeller 
  • Steeper control ramps allow a lower idle speed for significant energy savings – especially in the production of thin glass 
  • Energy savings can be up to 20% per operational cycle for 4-mm production, for example
  • The lightweight impeller construction increases working safety in case of an impeller-induced blower failure
  • Available as an option for new Glaston tempering lines and as an upgrade for existing tempering lines

VARIABLE SPEED BLOWER CONTROL

The Variable Speed Blower Control System (S™) upgrade ensures the highest quench energy efficiency, higher productivity with less changeover time and reduced peak power. 

Reference stories

Martin G, Sweden

“The RHC upgrade is a very nice package. A way to transform our 2008 furnace into a 2017 model that is up to modern standards. And no need for a bigger machine. It’s got the same layout without requiring any extra power. In fact, the furnace uses less power now.”
