HVAC systems are an integral facet of the modern industrial world; subsequently, proper maintenance is mandatory. Ascertaining the materials of construction in a system will determine the procedure to chemically clean and passivate. Ultimately, a cleaned and passivated system will increase heat transfer abilities and help protect the system from corrosion, plus increase flow rates with less pump power requirements, and provide a more efficient process.
