Our fogging systems are based on the adiabatic abatement of the air temperature obtained by atomizing the water at ambient temperature directly into the air flow feeding the compressor or condenser. This technology increase the performance of the gas turbines by recovering the loss of capacity and thermal efficiency losses resulting from a rise in the external temperature, and with the same production, reduces pollutant emissions. We provide fogging systems applicable to energy generation, in incineration and cement production both for retrofitting projects and for new installations. In waste-to-energy systems, fogging is applied under the air condenser fans and downstream of the economizer in the convective zone of steam boiler.


These systems are designed to distribute the demineralized water inside the air flow with semi-rounded arrays, swirl nozzles and high-pressure pumps. For turbines with power 30 ÷ 270 MW an increase of output power of 3 MW ÷ 18 MW can be achieved.


These systems can be installed externally of the air intake and are equipped with proprietary filters that retains all the spray droplet. For turbines power output 3 MW ÷ 20 MW an increase of output power of 0.5 MW ÷ 2 MW can be achieved.


With ECO-WETFOG™ the cooling is achieved via the evaporation of the water which is injected internally in the first stages of the compressor of the gas turbine (up to 15 - 20% of the gas turbine nominal power can be additionally achieved). For turbines power output 65 MW ÷ 270 MW an increase of output power of 5 MW ÷ 24 MW can be achieved.


The ECO-DFS ™ systems have a Double system that combines the internal air intake fogging after the filtration stage and nozzle arrays positioned on the duct walls. For turbines power output 65 MW ÷ 270 MW an increase of output power of power increase 5 MW ÷ 24 MW can be achieved.


The XXS systems have been developed for micro turbines dedicated to all small-medium capacity industrial applications such as food production, chemical industries and civil engineering buildings. With a return on investment usually within two years, or less in case of turbine > 500 kW.

These systems provide adiabatic humidification of the air but with a minimum air flow rate and a filtration system (1 or 2 Drop Safe type filters) downstream of the spray nozzles. For turbines power output 100 kW ÷ 1000 kW an increase of output power of 10 kW ÷ 80 kW can be achieved.
