- Process-specific configuration → Enables selection around temperature, pressure, fouling risk and materials
Schmidt-Bretten SIGMADUAL is relevant for plants where heat transfer has a direct effect on product quality, energy use and process continuity. It is selected for refrigeration, chemical and industrial processes where one side of the exchanger requires welded containment and the other side needs serviceable gasket access. For engineers and maintenance teams, the main value is a configurable exchanger concept that can be matched to heat duty, media properties, pressure drop and cleaning strategy without oversizing the installation.
SIGMADUAL uses semi-welded plate modules for duties with demanding media, refrigeration circuits or leakage-sensitive operation. Welded channels support containment on one side while the service side remains gasketed and modular. Schmidt-Bretten plate technology uses corrugated plate geometry to generate turbulence and support effective distribution across the heat-transfer surface. Depending on the variant, the exchanger can be configured with suitable plate material, gasket concept, connection type and frame arrangement so the thermal solution fits the actual process rather than a generic duty point.
Key technical parameters include laser-welded plate modules, double-welded seams, temperature range from -29 °C to 200 °C, vacuum to 30 bar, flow above 2,000 m³/h and DN100 to DN350 connections. Across the SIGMA family, available materials include stainless steels and special alloys, while gasket options include standard elastomers and PTFE-coated or application-specific variants where appropriate. These datapoints should be checked against the final media, temperature profile, pressure level and service requirements before selection.
From a lifecycle perspective, the value of Schmidt-Bretten SIGMADUAL is not only thermal efficiency but also access, maintainability and adaptability. Correctly selected plate geometry can reduce fouling risk, pressure loss or contamination risk, depending on the process. AxFlow can support product selection, spare-parts planning, service questions and availability so the exchanger remains aligned with process continuity and total cost of ownership.
