PAD-XS Adiabatic Dry Cooler

PAD-XS adiabatic dry cooler: how it works

PAD-XS exploits the principle of adiabatic cooling to improve heat exchange efficiency: during warm seasons or the hottest times of the day, outside air is pre-cooled through a humidification process before being fed onto the finned coils. At other times of the year and day, PAD-XS operates as a standard dry cooler, with outside air as the only cooling medium.

All this results in lower fluid (usually water/water-glycol) outlet temperatures than conventional dry coolers, reducing energy use.

Some of the possible applications:

• mechanical industries,
• air conditioning in offices and hospitals,
• data centers.

Each unit in the PAD-XS series is fully accessible, for internal inspections, easily, quickly and safely. Low noise levels (a key aspect for civil settings) are also guaranteed.

Technical features of PAD-XS

• Operating modes: dry (dry) and adiabatic.
• Electronically controlled (EC) fans.
• Support structure made of press-folded galvanized sheet metal and then protected by a cycle of RAL 7016 epoxy paint.
• Heat exchange coil with copper tubes and aluminum fins. Coil angle, tube diameter, thickness and fin pitch designed to provide the best heat exchange performance with reduced airflow pressure drop.
• Adiabatic section composed of PVC flocked panels.
• Aluminum air inlet grille (easily removable) as protection of the adiabatic section.
• Temperature probes to measure outside air, fluid inside the coil, and humidified air inside the machine.
• Thermal capacity: 20 kW to 50 kW.
