Adiabatic Cooling Systems

Un sistema di raffreddamento adiabatico (dry cooler adiabatico per liquidi, condensatore adiabatico per gas) è un sistema che combina il principio di un dry cooler (raffreddatore a secco) con il pre-raffreddamento adiabatico dell’aria esterna.

Both systems use water, but in different amounts, in different ways, and with different levels of efficiency. The direct evaporative

Some main advantages can be enumerated, related to reduced water use and optimized operation during different seasons and times of the day.

Modern evaporative coolers use automatic blowdown systems controlled by conductivity sensors, partial recovery of discharge water, and optimized make-up strategies. Adiabatic systems, on the other hand—with the proper use of sensors and PLC-based parameter settings—use water only during periods of maximum thermal load, reducing overall consumption compared to traditional cooling towers (though with some loss of efficiency). The adoption of recovery circuits also allows part of the water to be reused in any cooling system that relies on this resource.

Adiabatic cooling systems (adiabatic dry coolers for liquids, adiabatic condensers for gases) are the optimal solution where the goal is to save water, either due to the absence of that resource or to risks associated with its management.

In an evaporative system, approximately 2% of the mass to be cooled evaporates and is released back into the environment.

During the design phase, the use of selection and configuration software makes it possible to compare different solutions—chillers, cooling towers, adiabatic coolers, or dry coolers—by simulating their seasonal performance and heat loads. These digital tools also estimate energy and water consumption and help optimize system sizing.

Alchemist is a patented solution from MITA Cooling Technologies that combines the useful effect of subcooling with the natural and efficient operating principle of an adiabatic cooler in a single device.

A fan draws in a portion of air from the outside environment and then runs it through a finned coil inside which circulates the refrigerant to be subcooled.
