EXTRA1 COMPACT- HEAT EXCHANGERS TECHNICAL DATA Cordivari Heat Exchangers, with tubes bent to the bottom, is able to heat the complete quantity of volume in an homogenous way. Energy storaging is therefore improved and Ignition time data have to be referred to the complete volume of the tank, while in a traditional straight heat exchangers equipped calorifires, a range between 9-17% of Volume remain cold.
