This Avantco evaporator drain pan and copper pipe is a direct replacement for the one that came with your Avantco BC-36 bakery display case. It replaces a worn or broken part to keep your unit operating efficiently. The evaporator drain pan is designed to mount underneath the evaporator to catch the water and prevent it from collecting inside the unit. This item also comes with a copper pipe, which is resistant to corrosion and ensures water is distributed safely.
