Fritz Winter Eisengießerei GmbH & Co. KG continues to invest in a future-oriented production strategy. At its headquarters in Stadtallendorf, the company is currently expanding and modernizing its manufacturing lines. A key component of this program is the delivery of around two dozen pneumatic conveying systems of the SP-HL type from KLEIN Anlagenbau AG.

Energy-efficient conveying with SP-HL technology

The robust SP-HL conveyors, used worldwide, enable continuous, gentle material transport thanks to their sophisticated design. This not only reduces system wear, but also significantly lowers energy consumption—by up to 50 percent on long conveying distances compared to conventional pressure vessel systems. As such, they make a vital contribution to both economic efficiency and the environmental performance of the foundry.

A shared goal: greener foundry operations

Fritz Winter and KLEIN Anlagenbau are pursuing a joint mission to optimize manufacturing processes while improving sustainability. The new systems:

minimize dust emissions and support compliance with strict air pollution control regulations,
reduce waste such as residual dusts,
and significantly lower overall energy requirements.

This approach enhances both production performance and environmental responsibility.

Centralized binder handling for the new core shop

In parallel with the conveying systems, the newly constructed core shop at Fritz Winter was equipped with a fully integrated binder unloading, storage, and supply system from KLEIN Anlagenbau. This installation includes:

a dedicated unloading station for silo trucks,
two double-walled 30 m³ storage tanks for the binder components,
and fully enclosed, double-walled supply lines with leak detection to the core production cells.

All system components have been designed with maximum environmental and operational safety in mind—an essential factor given the strict environmental regulations at the site.

With its investment in state-of-the-art pneumatic conveying and binder logistics technology, Fritz Winter strengthens its long-standing collaboration with KLEIN Anlagenbau. The result: improved material handling, reduced operating costs, and a further step toward a cleaner, more sustainable foundry operation.
