Apparatus for concentrating an aqueous solution of higher boiling point organic antifreeze medium includes a casing having a first and second upright legs connected by a third inclined leg. The first leg is open at the upper end to provide an ambient air inlet and includes a spray discharge nozzle, heating coils, an extended evaporation surface and a sump vertically disposed with respect to each other. The second leg constitutes a multistage reflex chamber having a plurality of alternately disposed reflex cooling coils and reclaiming screens of glass fiber cloth, each screen formed in a plurality of zigzag stretches. The third leg connects the first and second legs and is inclined downwardly from the second casing to the first casing to permit migration of liquid to the sump. A pump and conduits are provided to supply liquid from the sump to the discharge nozzle. A blower is provided in the second leg to draw ambient air and evaporated solution from the air inlet through the first leg, connecting leg and second leg respectively.
