CETAG – Casthouse Engineering and Technology AG, Switzerland

CETAG - Casthouse Engineering and Technology AG of Switzerland is a well established supplier of casthouse process know-how and equipment servicing the worldwide aluminum industry. Our employees gained their in-depth knowledge over decades of being members of the aluminum industry community and offering their services to global customers to improve their processes and equipment. Our focus is not only on a single activity or piece of equipment but on the evaluation and improvement of complex cast house operations.

Casthouse Engineering and Consulting
CETAG provides studies, equipment evaluation reports and services to optimize existing production processes or plants. Examples of our services include preparing a feasibility study for a new casthouse or identifying measures for optimizing operations (e.g. to increase energy efficiency of a melting furnace, dross handling and processing, ...).

Equipment Supply
CETAG supplies various types of melting, holding furnaces and associated equipment. These furnaces are optimized for operator friendly operation, ease of maintenance, low metal losses and to minimize energy consumption.

CETAG is a supplier of the well-established dross cooling technology. This allows for cooling of dross to temperatures around 100ºC within 15 minutes. This quick and gentle process assures that a large portion of the "free" aluminum contained within the dross will be saved from oxidation and available for further recovery. Simultaneously the dross is reduced to a granulate and can be classified into aluminum granulate and fines, allowing for easy handling during further processing.

CETAG offers more than dross cooling technology. Part of our evaluation process involves examining existing equipment and preparing recommendations on how production processes and equipment can be improved to minimize metal loss and the amount of dross created during the melting process.

Pyrotek Celebrates 60+ Years of Innovation
When Pyrotek® was founded in 1956 in Spokane, Washington, USA, it manufactured one product: high quality, low cost sewn fibreglass bags for molten aluminium filtration. At the time, the aluminium industry within the USA's Pacific Northwest was robust, with Kaiser Aluminum Corp., Alcoa Inc. and Reynolds Metals Co. plants taking advantage of the region's inexpensive hydroelectric power. Pyrotek soon found it had a niche, expanding its product offerings and strategically opening branches near aluminium plants around the USA.

By the end of the 1960s, Pyrotek had crossed the ocean, entering Australian, Scandinavian, African and other international markets. Today, the company operates more than 80 sales offices, research centres, and manufacturing plants in 35 countries.
