For decades, our Schmidt-Bretten SIGMA plate heat exchangers have been successfully used in the chemical industry. We provide solutions for the most diverse applications, including the cooling and heating of base, intermediate, and final products; heat recovery; and the tempering of containers, reactors, and autoclaves.

Our solutions offer superior efficiency and operational safety, low capital outlay, and the ability to accommodate required capacity changes. Capabilities in CIP or mechanical cleaning, as well as the utilization of special materials for critical media, have made our plate heat exchangers an important component in chemical production processes.

For extreme temperature and pressure applications, our Basco custom shell and tube heat exchangers are available. 

Thanks to our track record around the globe, we are a recognized leader within the chemical industry.
