Stainless Steel Heat Exchanger Vs Aluminium Heat Exchanger

Stainless steel resists corrosion in a wide range of pH levels, while aluminum will corrode if the proper fluids are not used to produce and maintain a narrow pH range. Aluminum heat exchangers require the use of special manufacturer- recommended heat transfer fluids and inhibitors when starting up and maintaining the system. If the proper fluids are not used, there is a risk of damage to the heat exchanger, and manufacturers of aluminum heat exchangers may not honor their warranties if the proper fluids have not been used. Stainless steel heat exchangers, on the other hand, do not require the use of special fluids and are compatible with plain clean water and commonly available propylene glycol.
