UniWeld

UniWeld combines the advantages of conventional shell and tube heat exchangers with plate heat exchangers due to its design and construction : high pressure and temperature with small dimensions, high heat transfer coefficients and low fouling. UniWeld heat exchangers are formed by welded round plates installed in a shell, forming 2 separate circuits. There are no gaskets or brazing and all connections are welded, avoiding leakages and interruptions of the production. Opeanble shell for maintenance and cleaning is available on request.

UniWeld – Hybrid
UniWeld-Hybrid are fully welded plate heat exchangers, enclosed in a shell.
This mixed construction is based on the design of the heat-transfer channels, which are on one side in the tube design (shell side) and on the other side in a plate design (plate side). UniWeld Hybrid exchangers utilize in this way the advantage of tubular heat-exchangers (high temperature, pressure resistant and solid construction) and plate heat-exchangers (high heat transfer, minimal space and low logarithmic temperature difference) in a compact system.
