Inlet Air Cooling System

Product outline

This system uses fine fog (Semi-Dry Fog®*1) to cool gas-turbine intake air by 2–4°C and help boost electric power generation output in the summer when high outdoor temperatures reduce generation efficiency.
Using simulation-based analyses, wind tunnel tests and other such approaches, we propose nozzle layouts optimized for operating environment conditions such as air-intake filter chamber shape, while offering controls tailored to onsite operating condition requirements.


• Hydraulic intake-air cooling system utilizing Semi-Dry Fog®.(*1)
• Cools intake-chamber air by 2–4°C in gas turbines, gas engines and diesel engines.
• Mitigates declines in electric power generation output caused by high outdoor temperatures during the summer.
Although specific figures vary depending on the equipment used, an ambient temperature rise of 1°C usually educes generation output by 0.6–0.8%.
• Minimizes volumes of wastewater drainage.
• Support customers in site investigation, layout design, installation work and maintenance services.

*1) We define Semi-Dry Fog® as a fog with a mean droplet diameter (mean fog droplet size) of 10-30 μm.
This highly useful fog features fine droplets and does not include large droplets which can result in wetting of objects and surfaces.


Gas turbines: Increase in power output (by cooling the inlet air)
Gas engines: Preventing knocking, cooling the engine compartment
Diesel engines: Reducing NOx emission volumes
