Dry Fog Humidification That Never Gets Anything Wet
Smart Fog’s patented dry fog technology adds moisture as an ultra-fine fog that evaporates before it lands. You get precise humidity control without wet floors, dripping equipment or mineral dust.
Humidity Control Without the Usual Trade-Offs
Conventional humidifiers make you choose between accuracy, cleanliness and running cost. Dry fog removes that compromise.
Precise Humidity Control
Hold relative humidity steady across the whole space, so processes and materials stay in spec.
Zero Wetting
Droplets evaporate before they land, so floors, products and equipment stay dry and mold has nothing to grow on.
Evaporative Cooling
The same fog that adds moisture also absorbs heat, cutting heat stress and cooling loads.
Low Energy Use
No steam boilers to run. Dry fog uses a fraction of the energy of steam humidification.
Moisture So Fine It Evaporates in the Air
Dry fog is a fog of water droplets small enough to evaporate almost instantly, before they can settle on a surface. Because the water turns to vapor in the air, it raises humidity without leaving anything wet behind.
Smart Fog developed and patented this dry fog technology, with the smallest water droplet size in the industry. That is what lets our systems humidify large commercial and industrial spaces evenly, with no puddles, drips or white dust.
What dry fog delivers
- Even humidity with no hot and cold spots
- No puddles, drips or slip hazards
- No mineral dust on products or equipment
- Self-cleaning nozzles and very low maintenance
- Clean, residue-free operation
From Dry Air to Stable Humidity in Three Steps
Every system is engineered around your space, airflow and humidity targets.
Measure
Humidity sensors monitor your space continuously and tell the system exactly how much moisture to add.
Atomize
Patented Smart Fog nozzles turn water into dry fog. Self-cleaning nozzles keep output consistent with minimal maintenance.
Absorb
The fog evaporates into the air before it reaches any surface, holding relative humidity within ±1-2% of your setpoint.
Traditional Humidifiers vs. Smart Fog Dry Fog
Here is what changes when you switch from steam, spray or ultrasonic humidification to dry fog.
Traditional Systems
- Wet floors and slip hazards from large droplets
- Mineral dust deposits on equipment
- Nozzle clogging and frequent maintenance
- Uneven humidity with hot and cold spots
- Bacteria and mold growth from standing water
- High energy use from steam boilers
- ±5-10% RH accuracy at best
Smart Fog Dry Fog
- Zero wetting: droplets evaporate before landing
- No mineral dust: clean, residue-free operation
- Self-cleaning nozzles, very low maintenance
- Uniform coverage across the whole space
- No standing water, no bacterial growth
- 99% less energy than steam
- ±1-2% RH precision

Straight answers to what facility and engineering teams ask us most.
What is dry fog humidification?
Dry fog humidification adds moisture to the air as droplets so fine that they evaporate before they can land on surfaces. It raises relative humidity without wetting floors, products or equipment.
Will dry fog make my equipment or products wet?
No. Because the droplets evaporate in the air, nothing gets wet. That is the core difference between dry fog and spray or misting systems.
How accurately can Smart Fog control humidity?
Smart Fog systems hold relative humidity within ±1-2% of your setpoint, compared with around ±5-10% for many traditional systems.
Does dry fog leave white mineral dust?
No. Smart Fog dry fog operates clean and residue-free, so you do not get the mineral dust deposits common with some other humidifier types.
How much maintenance does a dry fog system need?
Very little. Smart Fog nozzles are self-cleaning, which keeps maintenance low and output consistent.
Which Smart Fog system is right for my facility?
It depends on your space, airflow and humidity targets. In-room (ES100), in-duct (TS100), mobile (ES100M) and custom grid (MS100) systems cover most needs. Talk to an engineer for a sizing recommendation.
