The Process Therm exchanger is derived from exchangers with a calender and is additionally equipped with sections for the distribution of incoming and outgoing air, in turn integrated with service equipment such as the washing system (hoses and nozzles), demisters, manholes and more.

Process-Therms are used in particular where relative humidity and dust are present in the gas stream: a typical example is spray-drying installations for the production of milk powder.  With Process-Therm, it is possible to recover some of the energy from the air extracted from the process that would otherwise be dispersed into the atmosphere, and which is used to preheat the fresh process air entering the plant.

FIC is able to carry out the thermal and constructive sizing of both the downstream and upstream sections.

FIC heat exchangers can be built with any type of stainless steel or duplex, and for operating conditions that fall within a wide range of pressures and temperatures. They are designed using calculation codes linked to the PED 2014/68/EU regulation and in compliance with AD2000, ASME and EN calculation codes.
