COOLING UNIT
The purpose
of this unit is to reduce the temperature of the cooling water
when it circulates in a closed circuit through the plant.
A closed circuit
of chilling water for plant cooling is necessary when for local
reasons water must be saved, or its temperature is too high.
This unit operates
under vacuum to facilitate the evaporation of some water of the
cooling circuit. The partial evaporation of water removes the
latent heat from the mass still liquid.
This evaporative
cooling system can be replaced by a water chilling unit.
