A condenser misting system installed in your air conditioner not only enables more effective cooling and power savings but also reduces wear on your equipment by lowering its workload.

Evaporative pre-cooling or adiabatic pre-cooling systems can be easily installed to new or existing air-cooled condensers. Custom fabricated and installed in front of the coil faces of the condensers, the misting system atomises water at high pressure in the incoming airflow. As the water is atomised down to between 5 and 10 microns, the fog flash evaporates, cooling the air entering the coil unit.

The most effective way to operate pre-cooling systems is to evaporate the water in the air in front of the coils, before it goes through the coil unit. This works more efficiently than the method commonly used by building owners and air conditioning contractors, wherein a struggling unit is sprayed with water from an irrigation system or garden hose to cool the coils. 

Using a condenser misting system to pre-cool the air before it enters the coils delivers far more effective cooling as the full airflow is still able to flow over the coil fins. Wetting the coil fins disrupts the airflow; with far bigger droplets of water needing to be evaporated, it is far less effective than evaporating the water in front of the coils with a condenser misting system.

Unlike most air conditioning systems, evaporative pre-cooling becomes more effective the higher the ambient temperature rises; at higher temperatures, more mist can be evaporated into the air, resulting in a bigger variance between the ambient temperature and the temperature of the air entering the coils. 

By lowering the workload on the air conditioning system via lower head pressures within the compressor system in the condenser, wear and tear on the overall system is greatly reduced. High head pressures within a system will shorten the life of the compressor whereas lowering the head pressures through pre-cooling will extend the life of the condenser unit.

Coil cool evaporative cooling has been shown in tests to reduce power use by over 30% in even moderately warm temperatures of around 33 degrees C. In higher temperatures, the power savings will be even greater.
