Cooling tower with closed circuit–type VK–Evaporative Cooler
The water that needs to be cooled flows via an inlet into a heat-exchanger coil system (primary circuit). The water for cooling, is wetting the heat-exchanger coil system, evaporates and cools the coils (secondary circuit).
In situations where clean, non-deposit forming or corrosive fluid is required for your cooling needs, Closed Circuit Coolers provide optimal performance.
The VK Evaporative Cooler comes in a comparative compact design.
The units can be installed outdoors without requiring a large installation area. With the appropriate precautions (antifreeze), year-round operations are no problem.
Benefits

very low water outlet temperatures reachable through evaporation
-
hybrid / dry-cooling operation possible
-
low complexity and very solid system performance
-
low noise level because of closed construction
-
low energy consumption
-
very economic and efficient way to cool
-
water quality in accordance with VDI 3803 without limitation applicable
-
easy accessibility for maintenance due to design of the units
-
outside or inside installation of the units (inside installation of the units with corresponding ducts possible)
-
additional reduction of noise level possible (silencers)
-
winter-operation also possible without antifreeze (glycol)
