Pre-cooling with FOG system

In extreme heat, many conventional air conditioners either shut down or fail due to excessive ambient loads on the condensing coil. Many engineers have attempted to solve this problem by spraying the coil with water only to find out that this causes calcification and deterioration of the coil. Calcification reduces the heat transfer efficiency and increases operating costs in a more moderate ambient temperature.

NDLE offers standard packages for industrial, commercial and private air conditioners to "pre-cool" the air without wetting the coil as it enters the unit through our FOG system. By utilizing this package the unit can operate more efficiently with an extended operating life. Tests have shown that when the NDLE FOG system is installed the EER (Energy Efficiency Rating) of the units can be reduced by up to 55%. The power usage (in kW) can also be reduced by up to 33% depending on the climatic conditions.

By coupling the FOG SYSTEM to temperature and humidity sensors, the system comes on when the a/c unit is under extra heavy ambient load. Experience has shown that the NDLE’s pre-cooling system is an energy saving device that can reduce electrical consumption and not damage the condenser coils.
