A heat exchanger is a system used to transfer heat from one medium to another. Heat exchangers can be used in the process of both heating and cooling. One of the most widespread uses of heat exchangers is for air conditioning and refrigeration, which are commonly referred to as ‘coils’. Heating, ventilation, air conditioning and refrigeration (HVAC/R) systems employ various technologies to regulate temperature, humidity, and maintain air quality. HVAC/R systems provide heating and/or cooling for residential, commercial, industrial and institutional buildings.

Corrosion protection standards drive the development and determine the performance of coatings for this market estimated to be worth over USD 250 billion in 2022. So, how can the investment made to design, build and install these HVAC/R assets be protected?

Coatings. HVAC/R coatings are designed to protect the metal ‘tube & fin’ heat exchanger coil, which may be subjected to the stresses of an aggressive service environment, resulting in corrosion and the ultimate failure of the HVAC/R asset.
