Difference between air-cooled and water-cooled units?

The new PRESTO units are available with air or water cooling. Air-cooled units do not require water and can be installed anywhere.
If you expect to move the unit frequently, an air-cooled unit will be the best choice. However, it is important to remember that these units draw in air and will slightly elevate the ambient temperature during operation.
Water-cooled units must be connected to an existing cooling water line. These units are even quieter and can be completely enclosed during operation. The new PRESTO uses robust, maintenance-free heat exchangers for water cooling. Clogging of the heat exchanger by particles or impure water is virtually eliminated.
