Immune to formicary corrosion

The issue of formicary corrosion has provided major HVAC system manufacturers with the motivation to move forward with the elimination of copper tubes from their tube and fin evaporator designs. And to replace the copper with aluminium, in an all-aluminium solution.

What this does is create a dual benefit of lower initial raw material costs and a reduction of warranty costs, since it is estimated that 10 percent of indoor heat exchangers fail prematurely due to formicary corrosion.

Aluminium is immune to formicary corrosion.
