Solex to highlight sand conditioning at AFS Metalcasting Congress

Metlcasting Congress LARGE

Three takeaways on how indirect heat exchange is changing the game

Solex Thermal Science is looking forward to celebrating the theme of Made for Today. Ready for Tomorrow at the American Foundry Society’s 2021 Metalcasting Congress – the first virtual version of the signature event in the association’s 125-year history.

Taking place from April 12-22, this year’s premier conference and trade show for the metalcasting supply chain will bring the best in technical education, management expertise, networking and sales under one virtual roof.

Solex will be on hand as an exhibitor in the Mold, Core & Sand Preparation area of the Exhibit Hall where company representatives will showcase how we provide an innovative way to condition foundry sand more efficiently and effectively

Here are three takeaways you can expect after visiting Solex’s booth. We look forward to seeing you there!

1. There’s a better way to control temperature

Indirect plate heat-exchange technology acts as a temperature-controlled, sand-conditioning system that can deliver accurate and consistent temperatures within ±1°F of the desired setpoint temperature.

“Sand temperatures provided by current technologies can vary by ±20°F, which can lead to expensive inefficiencies such as productivity losses, core scrap, and casting scrap and rework,” says Scott Harris, Regional Director, Americas for Solex Thermal Science.

“With Solex’s technology, the temperature is maintained at all times, even when the sand throughput is intermittent, running continuously or stopped for a long period of time. This provides great flexibility for managing production operations."

2. You can control dust

Direct-contact heat exchange solutions result in large amounts of silica dust being emitted from the process. In addition to the need for additional equipment required to clean the air, this also contributes to undesirable employee exposure to respirable crystalline silica.

“With indirect heat-exchange technology, the sand product does not come into direct contact with air during heat transfer,” says Gerald Marinitsch, Global Director, Industrials for Solex Thermal Science.

“And because air is not used in the heating or cooling process, there’s no need for blowers, ducting and expensive air-handling and -cleaning equipment and the related complexity of operating these integrated systems”

3. Do more in less space

With a footprint of just three feet by three feet, the modular design and vertical orientation of plate heat exchangers make them an ideal choice for debottlenecking or revamping plant operations.

“You can easily increase sand cooling capacity without sacrificing additional floor space,” says Harris.

“Plant operators gain the dual benefit of being able to retrofit their existing operations with minimal modifications, while also handling much higher throughputs because of the ability for plates to offer more heat transfer area than the equipment being used today.”
