Dry cooling and hybrid dry coolers
The dry cooler uses a closed cooling circuit to cool the desired medium (usually a water-glycol mixture or pure water), releasing the extracted heat to the ambient air. As with closed cooling systems, the cooling medium is passed through a separate tube bundle heat exchanger for this purpose. Fins are often mounted on the tube bundles to increase efficiency while maintaining the same space consumption.
A hybrid dry cooler is a mixed form. The heat to be dissipated can be discharged into the environment both by air heating (sensitive form) and via evaporated water (latent form).
Dry cooling has the general advantage that no water needs to be added externally to achieve the desired temperatures. As a result, they are used where water connections are lacking, or the supply of water would simply be too expensive.
MULTI Kühlsysteme GmbH currently offers dry coolers in three different series. Classic dry coolers of the TDH series are available in both horizontal and vertical versions. Particularly space-saving V-shaped models are also available as hybrid dry coolers
