SORG marks one year of successful operation for another CLEAN Melter®, this time at CRISAL, replacing the previous regenerative F1 Endport furnace. This investment was supported by the Recovery and Resilience Plan (PRR) under the ECP Agenda – Ecocerâmica e Cristalaria de Portugal.

CRISAL is the one-of-a-kind Portuguese glassware producer, located in Marinha Grande, a well-known area for its glass industry. It is part of the Leerdam Crisal Group (LCGlass), a world-renowned glassware manufacturer.

The CLEAN Melter® is an oxi-hybrid melter designed for an electricity share of up to 80%, with the remainder provided by gas, and with the capability for later heating with hydrogen power built in from the start.

With a melting surface of approx. 55 m², the melter represents a significant step forward in reducing CRISAL’s CO₂ emissions as part of its sustainability strategy.

SORG supplied the design and equipment (including the electrical and fossil heating systems) as well as the SCADA furnace control software. SORG also provided the conditioning system, consisting of an STW®-type distribution channel and five forehearths,  STF® type.

The dismantling of the previous melting tank and construction of the CLEAN Melter®, including heating-up and filling, was carried out by SKS, a company of the SORG Group.

We would like to thank CRISAL and LCGLASS for their good cooperation in the project.
