PAD-XS Adiabatic Cooler

PAD-XS adiabatic cooler: operation

With the PAD-XS adiabatic cooler (or adiabatic dry cooler), operations managers achieve adiabatic cooling optimization even for low flow rates and thermal capacities.

As with any adiabatic system, the mode of operation is twofold, depending on the time of day and year (all parameterizable thanks to the standard PLC).

• Dry operation: outside air is drawn in and conveyed to the finned coil. The humidification process is deactivated, there is no presence of water, and the adiabatic section is dry.
• Adiabatic operation: outside air is drawn in and passed through the adiabatic section (protected inside the machine). The adiabatically cooled air (i.e., at a lower temperature than the outside air) is routed over the finned coil, thus increasing the cooling effect of the fluid.

The system involves the direct use of mains water that requires no specific treatment. In general, the amount of water is minimal and limited to the summer season at a predetermined threshold. No accumulation, no stagnation.

Each unit in the PAD-XS series is fully accessible, for internal inspections, easily, quickly and safely. Low noise levels guaranteed.
