SINGLE-COIL INOX PRIMARY HEAT EXCHANGER:

A compact heat exchanger with a large water volume and a single coil, in which the cross-section of the coil is pear-shaped. The inside of the heat exchanger consists of a combustion chamber, a condensing chamber and a metal sheet covered with glass fibre separating the two chambers.
The fact that the coil is made from a single tube - including the flow and return connections - has the following advantages:

o Prevents the build-up of dirt and deposits;
o Evenly distributed water flow, ensuring uniform heat exchange;
o The water flow will remain stable throughout the life of the product;
o Reduced heat and flow losses thanks to the optimised coil;
o The strength and construction of this heat exchanger make cleaning easier.
Thanks to its shape, it can be used both in new and, if properly installed, in old heating systems.
