Flash Coolers

Flash Coolers are similar to evaporators in that they utilize a vacuum vessel to reduce the temperatures at which the liquid boils. The flash cooler’s purpose is not to concentrate products but rather to cool them, by admitting them into a vessel, in which the boiling point has been reduced by the vessel being operated under vacuum. Many liquid products benefit by prompt cooling after thermal processing, either in pasteurizers or evaporators.

Where cooling duties are particularly rigorous, Marriott Walker flash coolers can be provided in multi-stage configurations, to accomplish the required product cooling task.

Our “vapor-in-tube” surface condensers, used in conjunction with flash coolers, provide for sanitary capture and re-use of condensed flash vapors if circumstances require it.
