This Avantco 19386303 evaporator coil is a direct replacement for the one that came with your Avantco air curtain merchandiser. An essential part of any refrigeration system, the evaporator coil runs refrigerant through a coiled frame, absorbing heat from the interior of the unit and cooling it down. It can be used to quickly and easily replace a broken coil, minimizing downtime. It's compatible with Avantco HAC-28W and HAC-28B air curtain merchandisers.
