The 5 Series product line now joins the 3 Series products in offering the next generation of aluminum air coils. All-aluminum coils were first developed to meet the rigorous demands of commercial products. They provide a durable, single-metal solution that eliminates the threat of formicary corrosion and reduces the chance of galvanic corrosion. The new air coils are easier to recycle and use less material than comparable copper coils. The rollout of aluminum air coils in the 5 Series 500A11 product line are: Models 012 – 030; Models 038 – 049; and Models 060 – 072, which are set to roll out January 1, 2016.
