It is used when the flow rates of the system are higher than those achievable by the boiler and its sizing must take into account the average speed of the fluid both inside the main body and on the connection attachment.
Complete with insulation, thanks to the compactness and installation flexibility, they allow the protection of the boiler body and the durability of the generator. The particular design of the plates allows to obtain high performances in terms of heat exchange and reduced pressure drops.
