GLASS SERVICE (GS) is proud to introduce ES4™, the next generation of its renowned Expert System technology, scheduled for release in early 2027. More than a control system, ES4™ is a complete performance platform designed to help glass manufacturers anticipate, optimise and improve furnace performance.
Built around future-aware predictive control, extended optimisation horizons and live fuel cost integration, ES4™ enables smarter operational decisions while improving furnace stability, reducing temperature variation and supporting higher yield.
Through the integrated ESPilot™ environment, operators and management gain real-time visibility across multiple furnaces, transforming operational data into actionable insight from anywhere in the plant.
Key benefits include:
- Future-aware control and predictive optimisation
- Dynamic fuel cost optimisation linked to live energy prices
- Real-time visibility across multiple furnaces
- Improved stability, consistency and operational transparency
ES4™ transforms Expert System from a control solution into a true performance platform, helping glass manufacturers anticipate, optimise, enforce and learn.
Existing ESIII™ customers can upgrade using their current integration architecture and OPC (Open Platform Communications) connectivity, ensuring a straightforward transition to the next generation of intelligent furnace operations.
