FAQs

Mee Industries regularly guarantees the amount of cooling a system will produce on a hot day. MeeFog systems have a 12-month warranty. Longer warranty terms are available on request.

MeeFog systems can be used whenever the temperature is above freezing. It is usually possible to cool by at least 10°F (5.5°C) even on humid afternoons in a tropical climate.

Yes. You can view MeeFog case studies for several installations on steam condensers, AC condensers, etc. at this link on our website.  (link here https://www.meefog.com/category/our-solutions/fog-cooling-for-gas-turbines-heat-exchangers/heat-exchanger-pre-cooling/ )

Typical lead-times are 12 weeks for smaller projects and 24 weeks for larger projects. The MeeFog pump skids are typically fully assembled. MeeFog factory installs the fog nozzles in the nozzle lines and conducts factory testing. Nozzle lines typically ship in 20-foot sections. Installation consists of bolting the pump skid to a foundation and installing the feedlines and nozzle lines. Mee Industries provides all drawings and a technical advisor for the installation.

Fog nozzles, fog nozzle lines, feedlines, and pumps are all stainless steel, which ensures long life and minimal maintenance.

Water fallout is reduced or eliminated by using many fog nozzles with flow rates that are low enough to prevent over-wetting of the coils. Overspray can provide more cooling than would be possible from just evaporatively cooling the inlet air because water can be evaporated off the hot coils themselves.

MeeFog systems can operate for more than 30 years with proper maintenance. The fog nozzles themselves do not wear out and can be used for the life of the system, assuming water treatment is maintained.

Fog systems require very little maintenance. Inlet water filters need to be changed periodically, and any water treatment equipment will need regular service. The high-pressure pumps are water-lubricated, multi-stage centrifugal pumps that can operate for many years with very little maintenance.

MeeFog systems can be controlled based on ambient temperature. For example, for a system with two stages, the first stage can be turned on when the ambient temperature exceeds 85°F (30°C), and the second stage can be turned on when the ambient temperature exceeds 90°F (32°C). The temperatures at which fog stages operate can be selected based on climate data and process requirements. MeeFog systems can also be controlled based on the temperature of the cooled fluid when it leaves the heat exchanger.
