Alfa Laval, a leading global provider of specialized products and engineering solutions, developed AlfaDisc, a new hybrid heat exchanger to combine the thermal efficiency of a plate heat exchanger with the pressure and temperature resistance of a shell & tube unit. The new AlfaDisc all-welded exchanger is ideal for duties involving high pressures and temperatures such as steam heating, gas and refrigerant cooling, condensation and applications handling aggressive fluids.

A feature of the design is that when only one side of the exchanger is subject to corrosive conditions, the two exchanger elements can be fabricated from different materials. This means standard materials can be employed on the non-corrosive side with exotic materials restricted to the corrosive side, enabling significant cost savings to be made.
