A heat exchanger system facilitates the transfer of heat energy from one system to another.
You can use them for both heating and cooling processes.
Although you can make heat exchangers from different metals, these systems are made from titanium metal.
Unlike the other predecessors, titanium heat exchangers are totally immune to corrosion.
However, to work at full efficiency the device requires more surface area and a higher fluid flow rate.
In most cases, you will find coil patterns.
This is because they maximize the surface area of the tubes.
