Italian aluminium radiator manufacturer Global Radiatori has installed a new Westomat dosing furnace featuring StrikoWestofen’s next-generation ProDos4 control system. The move follows energy savings of up to 30 per cent achieved after replacing gas-fired holding furnaces with Westomat dosing technology.

The new Westomat was installed as part of a new automated die casting cell at the company’s Rogno production facility in northern Italy. It follows the successful introduction of two Westomat furnaces in 2021, which delivered immediate improvements in metallurgical performance and energy efficiency.

“It was from the beginning a great success,” says Sandro Panteghini of Global Radiatori. “Coming from old gas-fired holding furnaces, we immediately recognised a great step forward in metallurgical quality. At the same time we significantly reduced energy consumption and our CO₂ emissions went to zero.”

Performance drives repeat investment

Founded in 1971, Global Radiatori manufactures aluminium radiators for domestic heating markets worldwide, exporting around 75 per cent of production to approximately 50 countries. The company produces more than 14 million radiators per year, making consistent melt quality and process stability critical to maintaining efficient high-volume production.

Following the performance of the first installations, Global Radiatori made the decision that all future die casting cells would be equipped with Westomat technology – a stance this new addition reflects.

Supporting the shift toward lower-carbon die casting

Across the die casting industry, many manufacturers are moving away from gas-fired holding furnaces toward electric dosing and melting technologies as part of wider decarbonisation strategies. Electric systems can reduce energy consumption while eliminating direct combustion emissions from furnace operation.

For Global Radiatori, the transition to Westomat dosing technology has supported both operational efficiency and sustainability objectives.

Digital integration improves dosing accuracy

At Global Radiatori, the Westomat furnaces are digitally connected to the die casting machine (DCM). Data from the machine’s PLC - specifically biscuit thickness measurements - is used to automatically adjust the aluminium quantity delivered to each shot.

This closed-loop approach enables highly accurate dosing and stable casting conditions during production.

Operators report that the ProDos control system with biscuit correction is both intuitive and flexible to operate.

“The ProDos4 control system is easy to use, precise, and very flexible to our needs,” says Panteghini. “Continuous innovation is important for us as a company, so it is good to see the technology we love evolving as well.”

Strong technical support

Global Radiatori also highlights the role of StrikoWestofen’s Italian partner, Smith & Mason, in supporting the project. “Both StrikoWestofen and Smith & Mason have been highly professional and always available,” says Panteghini. “Their support has been excellent.”

With measurable savings and improved process stability now proven in production, Westomat dosing technology has become a central part of Global Radiatori’s strategy to modernise its aluminium casting operations while reducing energy consumption and emissions.
