SORG Group has successfully delivered and commissioned a second furnace (F6) for Vetri Speciali, supporting the expansion of the company’s Gardolo production site in northern Italy. This project highlights the ongoing partnership between the two companies and reflects SORG’s leadership in advanced glass melting technology.
The new regenerative endport furnace spans 70 square metres and is designed to produce a wide range of glass colours including flint, amber, green, and dark green. It includes a working end and four forehearths, all engineered to maintain high efficiency, long-term durability, and consistent glass quality.
SORG’s comprehensive engineering package encompassed the planning of refractory and steel components, including platforms, furnace structures, and feeder equipment. The project execution, from steel assembly and refractory installation to final commissioning, was supervised by Nikolaus SORG.
The scope of supply included complete furnace equipment with advanced combustion systems (gas and heavy oil), electrical boosting, and control instrumentation. The glass conditioning system comprises one STW distribution channel, two SORG 340S+® forehearths, and two SORG 240+® forehearths—all equipped with Conti-Drain® technology. EME provided the EME-NEND-S2® batch charger. 
SKS was responsible for the full steel construction and hot insulation, covering the regenerators through to the gob points. They also ensured technical assistance during heat-up.
For control, SORG supplied a dual-redundant SCADA WINCC system with the ES III™ expert system, ensuring precise performance monitoring.
SORG expressed its gratitude to Vetri Speciali for their collaboration and looks forward to a long and efficient furnace campaign ahead.
