AlfaDisc is an all-welded circular plate heat exchanger based on the plate-and-shell concept, making it ideal for uses involving high pressures and temperatures.
The AlfaDisc all-welded plate heat exchanger provides the exceptional thermal efficiency and compactness of a plate-and-frame unit under conditions that would normally require a bulky, traditional shell-and-tube unit.

These heat exchangers have the added advantages of being able to deal with high-fatigue applications and tackle asymmetric flows, as well as allowing easy cleaning on one side.
The sum total of AlfaDisc advantages makes this design a highly competitive alternative to other types of welded heat exchangers.

AlfaDisc all-welded heat exchangers are designed for use with liquids, gases and two-phase mixtures at pressures up to 100 bar (CE/PED) and 47 bar (ASME) and at temperatures up to 540°C.
This plate-and-shell unit works well with aggressive media – such as organic solvents – that are beyond the capabilities of gasketed heat exchangers.
They can be used for a wide range of duties, including many types of heating and cooling, condensation, evaporation, reboiling and stream heating.

AlfaDisc units are currently available in three sizes, designated AlfaDisc 50, 100 and 150.
Special units can be supplied with a removable core.
