Electricity will play a major role in the ongoing energy transition to reduce CO2 emissions. Although electric melting of glass is an old technology, many aspects have to be considered to create an efficient system that is suitable for each specific glass production.

This training focuses on supply and hardware, from the electrical grid down to the electrodes and beyond, to provide you with a pragmatic level of understanding of the whole system.


  • Purpose of electrical boosting, from sustainability to flexibility
  • Melting zone, barrier and throat boosting
  • Electrode material, types, holder and cooling systems
  • Positioning of electrodes
  • Selecting the correct type of transformer, cables and busbars
  • Granularity, efficiency and types of control systems
René Meuleman
René Meuleman started his career in the glass industry in 1968 as an employee of Vereenigde Glasfabrieken, later BSN and Owens-Illinois. He built a broad experience in the design and development of electronic quality equipment for container glass manufacturing and was involved in the implementation of their first-generation electrical furnace boosting systems, PLC and DCS systems, as well as electronic timing systems for IS-machines. In 2007 he joined the Eurotherm by Schneider Electric group where he became responsible for the technical and commercial glass business development focusing on the automation and electrification of the glass industry. He started at CelSian in early 2021.
Sjoerd Stelwagen
Sjoerd Stelwagen studied Chemical Engineering at Eindhoven University of Technology. Directly after his study he started as a Technical Specialist at the Furnace department of Ardagh Glass in Dongen, The Netherlands, where he later became Batch and Furnace Manager. He then evolved as EHS manager for the Benelux plants. With more than 16 years of practical glass making experience, he joined Celsian in 2021 to work as a project manager and trainer.
