SIGMADUAL Semi-Welded Plate Heat Exchangers

Product catalog summary

Overview: The SIGMADUAL series is a line of welded plate heat exchangers developed for the thermal treatment of sophisticated media. These exchangers feature pair-wise welded plate modules, enhancing their suitability for complex applications.

Design and Construction: The product side of the heat exchanger is sealed using laser welds around the flow channels and ring gaskets in the port areas. The service side flow channels are sealed with elastomer gaskets, while the ports are laser-welded. This design increases operating safety through double welding for product separation.

Modular Flexibility: The modular construction of SIGMADUAL allows for high flexibility, enabling easy adjustments to operating parameters by changing or adding modules.

Applications: SIGMADUAL heat exchangers are applicable across various industries, particularly in process and refrigeration sectors.

Materials and Standards: Available in various plate and gasket materials such as NBR, EPDM, and FKM. The exchangers can be delivered according to PED or ASME Sec. III Div. 1 UG-11(c) standards.

Specifications: The document lists several models with specific port sizes, maximum operating pressures, and design temperatures. For instance, the SIGMADUAL M 25 model has a port size of 4 inches, a maximum operating pressure of 450 psig for stainless steel, and a design temperature range from -22°F to 390°F.
