Recommended System Components

Cooling large open spaces like warehouses, gyms, or greenhouses can be expensive and inefficient with traditional air conditioning. That’s where mist ventilation systems come in—combining ultra-fine water mist with powerful airflow to lower ambient temperatures and improve air quality in a sustainable way.

What Is a Mist Ventilation System?

• A mist ventilation system uses high-pressure nozzles to spray fine water droplets (10–20 microns) into the air. These droplets evaporate instantly, drawing heat from the surroundings—a process known as evaporative cooling.
• When combined with airflow from fans or natural ventilation, the cooled air spreads across the space, resulting in a temperature drop of 5–12°C. This makes it ideal for semi-enclosed or open industrial environments where mechanical cooling is not feasible.
