What API Schmidt-Bretten does

API Schmidt-Bretten GmbH & Co. KG is a German manufacturer of customized plate heat exchangers, headquartered in Bretten with 160 employees at its main site. Founded in 1879 by Wilhelm Schmidt based on a patented cooler invention, the company has operated continuously for more than 145 years and is organized as a family-run limited partnership (GmbH & Co. KG) registered in Mannheim. It operates as a subsidiary of the US-based API Heat Transfer Inc., an international group with manufacturing capacities across Europe, Asia, and America.

The company's product portfolio centers on four plate heat exchanger families covering a spectrum of pressure and temperature requirements: SIGMA (gasketed), SIGMADUAL (semi-welded), SIGMASHELL (plate and shell hybrid), and SIGMAWIG (fully welded). These are sold as customized thermal treatment solutions for pumpable media, primarily to customers in beverages and food processing, industrial manufacturing, and energy and power generation. Support offerings include spare parts, on-site maintenance, hotline services, and the SIGMACOVER annual service programme, which guarantees a 48-hour on-site response time and 10-20% OEM discount on plates and gaskets for programme members.

Revenue is generated through three channels: one-time capital equipment sales of new heat exchangers, recurring subscription revenue from SIGMACOVER and annual maintenance contracts, and transaction-based spare parts and emergency repair services billed on time-and-materials. The go-to-market is enterprise field sales with consultative customization, supported by the company's website, industry-specific finder tool, and downloadable technical resources. Pricing is quote-based for equipment; service programmes are invoiced annually in advance.

Core offering

API Schmidt-Bretten designs and manufactures customized plate heat exchangers — gasketed (SIGMA), semi-welded (SIGMADUAL), plate-and-shell (SIGMASHELL), and fully welded (SIGMAWIG) — for the thermal treatment of pumpable media across beverages and food, industrial, and energy/power generation applications. The company supports its installed base of more than 85,000 units worldwide with a SIGMACOVER annual service programme, OEM spare parts, and on-site maintenance and emergency repair services.

Product overview

API Schmidt-Bretten is a manufacturer of highly customized and efficient quality heat transfer solutions, offering gasketed and welded plate heat exchangers. The product portfolio consists of four core plate heat exchanger product lines: SIGMA (gasketed), SIGMADUAL (semi-welded), SIGMASHELL (plate and shell hybrid), and SIGMAWIG (all-welded). These products range from standard gasketed configurations for lower-pressure applications to fully welded designs for demanding high-pressure and high-temperature industrial environments. The company also provides supporting services including spare parts, emergency repair services, and the SIGMACOVER annual service program that guarantees a maintenance rhythm for heat exchanger fleets, including OEM parts and gaskets at discounted rates with guaranteed response times.
