WATER /WATER HEAT EXCHANGERS
These heat exchangers are designed for use in domestic boilers that combine heating with fast production of domestic hot water. This water runs inside a copper coil wrapped in three concentric spirals with different diameters.
The primary circuit is connected to the heating circuit and consists of a series of cylindrical baffles that force water to make multiple vertical passes in order to efficiently move against the outer surface of the copper tube.
Both internal circuits are welded to threaded connections for installing the heat exchanger in the plumbing circuit.
There is also a version for direct connection with a diverter valve for interchanging fluid flows when there is a request for domestic hot water. A version also exists for direct connection with a diverter valve for flows exchange when there is a request for domestic hot water.
