100% RH with No Wet Surfaces—the Science Behind Dry Fog | Newsletter Vol. 31

How Can Fog Be “Dry”?
Most people think mist leaves surfaces wet. So calling our ultra-fine fog “Dry Fog” can sound like a contradiction.

The fastest way to understand it is to watch what happens in a real space.
In this demonstration, we intentionally raised the room to 100% relative humidity (RH) — without getting anything wet.

Product used: AKIMist® “E” Dry Fog Humidifier

Ultra-fine droplets behave differently. When droplets become small enough, evaporation dynamics change — and surfaces can remain dry.

From Physics to Real Growing Environments

So what does ultra-fine Dry Fog actually enable in greenhouses?
In controlled agriculture, humidity consistency matters — but excess moisture can create problems for both crops and facilities.

That’s why Soil Doctor Consulting highlights IKEUCHI’s AKIMist® “E” as a recommended solution for precise humidity control.
It produces ultra-fine droplets that evaporate instantly without wetting plants or surfaces, helping maintain stable humidity levels.
It’s also low-maintenance and proven in commercial greenhouse operations.

Scaling the Principle to Industrial Power

Now scale that same principle to industrial power generation.
On hot days, gas turbine output drops as intake air density decreases. Gas Turbine Inlet Air Cooling (GTIAC) uses controlled fogging to cool the intake air, increasing density and helping maintain performance in extreme heat.

Our GTIAC solution combines engineered nozzle design, ultra-fine spray designed for full evaporation, and automatic flow control for efficient, uniform cooling — supporting stable power generation when temperatures peak.
