FAQs

Wet compression is a gas turbine power augmentation method that injects atomized water (fog) into the compressor. The fog evaporates giving an intercooling effect, which reduces the work of compression and increases available power, further boosted by allowing more fuel to be burned due to cooler discharge air.

We guarantee 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 pre-cooling 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, we’ve documented several indirect evaporative cooling projects showing measurable performance gains on steam condensers, AC condensers, and other systems. 

To install a pre-cooling system for heat exchangers, typical lead times are about 12 weeks for smaller projects and up to 24 weeks for larger ones. MeeFog pump skids arrive fully assembled, with fog nozzles installed and factory-tested.

Nozzle lines usually ship in 20-foot sections. Installation involves bolting the pump skid to a foundation, then connecting the feedlines and nozzle lines. MeeFog supplies all required drawings and a technical advisor to support the installation process.

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

MeeFog systems reduce water fallout by using many fog nozzles with low flow rates that prevent over-wetting of coils. Any overspray that occurs can boost indirect evaporative cooling, as water evaporates from the hot coil surfaces, improving overall heat rejection and system efficiency.

A MeeFog pre-cooler for heat exchangers 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.

MeeFog pre-cooling systems need minimal maintenance. Inlet water filters should be replaced periodically, and any water treatment equipment needs routine service. The high-pressure pumps are water-lubricated, multi-stage centrifugal units designed to run for many years with little maintenance.
