FAQs

The water should have low levels of calcium and magnesium since these minerals can form a hard scale that is difficult to remove from the heat exchanger fins. Mee Industries can help design a water treatment system that will ensure long life and minimal maintenance.

Yes. MeeFog systems can be easily retrofit to existing air-cooled heat exchangers.

Small droplets are important because they expose more of the water’s surface to the surrounding air. Water only evaporates from the surface, so exposing more surface area means the air can be cooled faster and less water drips off the heat exchanger. Dripping water is lost to the evaporative cooling process, so minimizing it saves water and ensures maximum cooling for a given water flow rate.

Fog systems can be designed to provide several stages of cooling. For instance, a system capable of 10 °F of cooling can be designed with two cooling stages of 5 °F each. This allows the operator to do only as much cooling as is needed, thereby conserving water usage.

Evaporatively cooling the airflow to an air cooled condenser allows the condenser to release heat more effectively which makes the chiller more effective on a hot day.

On a hot afternoon it’s possible to cool by 30°F (17°C) or more in an arid climate, at least 20°F (11°C) in a temperate climate, and at least 10°F (5.6°C) in a tropical climate.

Heat exchanger pre-cooling consists of cooling the air flowing to the heat exchangers to improve their performance on a hot day. MeeFog systems atomize water to create a fog of liquid water droplets that evaporate and cool the air.

The main difference in fog vs. steam humidification comes down to energy and efficiency. Steam Humidification: requires boiling water, has high energy costs, requires frequent maintenance, and uses chemicals to prevent scale buildup. Fog Humidification: uses high-pressure pumps to create a fine mist, consumes a fraction of the energy, and requires less maintenance. Both methods add moisture to the air, but fog humidification is more cost-effective, energy-efficient, and environmentally sustainable. For facilities seeking to replace steam humidifiers, fog systems offer equal performance at a much lower operating cost.

Fog humidification is ideal for buildings aiming for energy efficiency and sustainability. Because it doesn’t rely on boiling water, but instead uses a low-grade heat source like hot water loops directly in the air handler or warm return air, it dramatically reduces carbon emissions, utility bills, and maintenance costs. Whether in data centers, museums, hospitals, or manufacturing facilities, customers report measurable energy savings in humidification while maintaining precise humidity levels.
