SIGMAWIG ALL WELDED PLATE HEAT EXCHANGERS

SIGMAWIG – opens up new fields of application SIGMA plate heat exchangers are recognized worldwide for quality and reliability in thermal processes such as cooling, heating, pasteurising, evaporation and condensation. To meet the increasing requirements for plate heat exchangers in special applications, a new type of plate heat exchangers without gaskets called SIGMAWIG was conceived in a cooperation of Schmidt and Tenez particularly for • • • • chemical industry pharmaceutical industry industrial cooling heat balancing systems SIGMAWIG ST12 in a heating-cooling circuit for tempering of chemical...

SIGMAWIG – one application out of a vast multitude More than 10.000 SIGMAWIG prove under tough process conditions SIGMAWIG – main connection types Standard flanged connection Flanged connection with internal expansion joints Studded port with O-ring sealing between plate pack and pressure frame Availability of a variety of flanges, ranging from standards such as EN 1092 to ASME 16.5, as well as a number of other standards upon request. A construction for applications with frequent temperature changes that is proven in more than 1,000 installations. The advantages of this connection type are not...

SIGMAWIG – the optimal choice for critical process parameters Advantages weldings replace gaskets higher security level at critical process conditions e.g. steam, thermal oil edible oil e.g. condensation of refrigerants high pressure heating- or low temperature networks compact design minimum of space required, costs, savings and foundations, installation, piping homogeneous countercurrent flow efficient heat transfer small liquid content optimized control of process, higher level of security, when handling dangerous products SIGMAWIG ST40 tempering of chemical reactor / Bayer Chemicals, Leverkusen...

Technical details SIGMAWIG all welded plate heat exchangers consist similar to gasketed plate heat exchangers of a number of corrugated plates which are in this design not equipped with gaskets, but seal hermetically by TIG welding seams without filler against each other and to the outside. The loading capacity of this connection exceeds many times the crushing strength of gaskets. The fishbone geometry of the flow channels built by the plates effects high turbulences on the fluids, which result in optimum heat transfer. The countercurrent flow arrangement allows most efficient heat transfer. The...
