Schmidt® SIGMASHELL All-Welded Plate & Shell Heat Exchanger Our SIGMASHELL all-welded plate and shell heat exchangers offer a unique combination of the ruggedness and high-pressure capability of a shell and tube with the compactness and high thermal efficiency of a plate heat exchanger. Features:  Cylindrical shell design to handle high-pressure applications  High thermal efficiency and surface density  Fishbone corrugation for superior high and low heat transfer characteristics  Shell construction flexibility - All-welded for a gasket-free design - Accessible to one or two sides for...

Quality Construction Ensures Superior Performance and Reliability Our Schmidt® SIGMASHELL is a laser-welded design, providing greater cross-sectional weld area at minimum heat input and resulting in little change to material microstructure. Its smaller weld pool volume reduces the risk of sink holes and pores during solidification to prevent leaks. Our laser welding is more capable and stronger against failures along the circumferential weld seams. These advantages result in plate packs with a higher degree of integrity and a longer life cycle. from 150 (depending on number of plates and...

Cleaning of Heat Exchangers When cleaning heat exchanger plates, fouling layers are removed from the heat transfer surface, i.e., deposits formed during operation, which hinder the heat transfer. During operation any combination of the following kinds of fouling are possible:  Crystallisation fouling  Particle fouling (also sedimentating fouling)  Corrosion fouling  Biological fouling For welded plate heat exchangers basically two cleaning methods can be used: Chemical cleaning Mechanical cleaning Depending on the design of the Plate & Shell heat exchanger, chemical cleaning can be...
