The Dometic RHEU16 evaporator is a draw-through, ductable cooling/heating unit with a rotatable, variable-speed blower. Electric heat is standard. Its high-efficiency blower can be rotated to discharge air at the most efficient angle. Insulating foam covers metal surfaces in the air flow to prevent secondary condensation, and the positive-flow drain pan is lined with anti-slosh, antifungal foam. A vibration-isolation mounting system reduces noise and vibration. For use only with DX split-system air conditioners that have air- or water-cooled condensers operating with R-22 or R-417A refrigerant. One or two evaporators can be used with a single condensing unit of matched capacity.
