HIGH PERFORMANCES ANTILEGIONELLA® HEAT
EXCHANGER
D.H.W. OPTIMIZED ACCUMULATION
Cordivari Heat Exchanger , with tubes bent to the bottom, is able to heat the complete quantity of water in an homogenous way, also in the bottom area of the calorifier. This will
ensure total production of the storaged of D.H.W. in the calorifier. (10%-15% more than standard heat exchangers). Maximal hygiene will be gauranteed.
