Intelligent energy saving

The high number of hours per year in which Free Cooling systems can be used ensures that the air conditioning system energy consumption can be reduced by over 50%. This is reflected in an immediate environmental sustainability increase, thanks to a significant reduction in CO₂ emissions, and system operating costs.

Indirect free cooling

The Indirect Free Cooling system is characterised by a hybrid unit, consisting of a primary water circuit and a secondary direct expansion or chilled water circuit. The primary water circuit is connected to a dry cooler utilising outside air - a source of renewable energy - to cool water. The secondary circuit exploits mechanical cooling.

Self-adaptive set-point of the dry cooler

To maximise the efficiency of the Free Cooling system, the unit can directly regulate the dry cooler coupled to it. Thanks to the self-adaptive set-point function, the water temperature is optimised to the ambient conditions through the fan speed regulation. This leads to an increase in the system efficiency, allowing you to maximise the performance of both the Free Cooling and direct expansion circuits, ensuring highly efficient low condensing temperatures. In addition, the dry cooler fans will partially operate even with high ambient temperatures, thereby increasing the energy savings of the system.
