Dry Cooler - VCR

The Transcalor Adiabatic Dry Cooler is an industrial water chiller comprised of honeycombs (expanded copper coils in aluminum fins) in a V-shape, with fans at the top and water sprinkler heads on the sides, built within a stainless steel structure.

The adiabatic cooler functions according to the following principles: input the desired cooling set-point of the industrial water, the fans, which have a coupled speed inverter, will start up and gradually increase or reduce rotation speed, forcing outside air to the honeycombs, with speed control based on the temperature of the outgoing cooled water, such that when the system reaches 100% it will take advantage of adiabatic cooling, spraying water externally on the fins, allowing air to take advantage of the temperature of the wet bulb, which reduces the temperature of the external air that will come into contact with the fins and tubes that make up the coil, increasing the efficiency of the heat exchange system. The sprayed water is separate from the process water that is being cooled, and comes from an independent source dedicated only to wetting the surface of the coil.


The Adiabatic Dry Cooler is calculated in advance by the Transcalor engineering team, and can include the following options:

• Remote or on-site operation and monitoring panel

• Process water pumping skid fit to the individual curve of the facility

• Water pumping kit for the adiabatic water spray system

• Automation between the dry coolers and the pumping process


Dry Coolers are used to cool water for a wide range of applications, and can be expanded in parallel and allow adjustment of flow and holding pressure.


• Lower water use

• Closed circuit, which prevents deposits on tubes and equipment

• No risk of environmental contamination (Legionella)

• Eliminates chemical treatment

• Low noise level

• Lower operating cost

• Return on investment possible within two years
