Mixing cooler

Mixing coolers are used to cool hot wastewater before it is discharged into the drain.

Typical applications include, for example, process plants where contaminated, hot wastewater is being formed and steam boiler plants where the blowdown is cooled with untreated water while recovering the mixing cooler’s flash steam.

If the Gestra VDM is used to cool the blowdown from a boiler with the help of cooling water, it may cause the formation of sludge through the precipitation of carbonates. This can be avoided by flushing the unit regularly or by the addition of acid.
