ECOOLER: THE ECO-FRIENDLY ADIABATIC PRODUCT RANGE
Units designed to meet the increasing demand for free-cooling applications, they optimise the benefits coming from the adiabatic saturation of the air adopting a water recirculation system and electronically commutated fans. The water and power consumption are thus minimised, resulting in Energy Ratio maximisation and the possibility to use “free-cooling” applications throughout all the year.

How does it work
The PADS adiabatic panels , placed in front of the heat exchangers above the air flow, are uniformly wetted through a distribution system with water recovery. The air, passing through the panels, is humidified and cooled with values that change depending on the operating conditions. The water consumption is limited to evaporated water only.
This results in water savings of up to 90% compared to the consumption of products such as evaporative towers.
- Self-draining system: no risk of water stagnation. All the water is automatically drained every 24 hours.
- The system prevents the proliferation of legionella by avoiding droplets in the airflow.
- Ease of maintenance thanks to the full access to the inside of the unit; all the components of the hydraulic system are inspectable.

Adiabatic Saturation Theory
- Adiabatic saturation temperature is a thermodynamic property of humid air. It represents the temperature that can be achieved by air when it reaches saturation condition through an adiabatic transformation.
- The adiabatic saturation temperature falls – since evaporating water removes heat – though it is still higher than the dew temperature, as evaporation itself raises the partial pressure of water vapor.
