This Avantco 17811872 17 1/4" evaporator coil is a perfect replacement for the one that came with select CFD-1RR and CFD-1RR-G series units! 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.
