Four core components work together:
Wet pad system: High-surface-area honeycomb curtains made of specialized fiber materials are continuously moistened by circulating water.
Water circulation unit: A pump evenly distributes water to the top of the wet pad, forming a water film.
High-efficiency fan: Typically a low-noise axial flow fan, it generates a stable airflow and drives the air flow.
Intake and exhaust structure: Ensures a continuous intake of fresh air while hot and humid air is discharged in an orderly manner.
This process simulates the natural cooling effect of water evaporation, which not only reduces the temperature but also moderately increases the air humidity (relative humidity of about 75%) due to the evaporation of water. It is particularly suitable for industrial environments that require humidity regulation, such as textile workshops.
Key application scenarios
The high air volume (18,000-40,000 m³/h for a single unit) and fresh air operation characteristics of industrial air coolers make them an efficient and energy-saving cooling option in various industrial sites:
1. Warehousing and Logistics Centers
Large warehouses often have a problem with accumulated cargo hindering natural ventilation. A fan-cooling combination (industrial air coolers + large ceiling fans) can achieve three-dimensional ventilation:
The air coolers are installed along the walls or roof to continuously supply cool, fresh air. Large industrial ceiling fans promote air mixing and eliminate hot air stratification.
2. Manufacturing Workshops
Labor-intensive workshops (such as shoemaking and textiles): Workstation air supply is designed to directly blow air to workstations, improving cooling efficiency in crowded areas.
High-heat workshops (metallurgy and plastics processing): A high air exchange rate of 50-60 times/hour is used to quickly dissipate heat generated by equipment.
Semi-open workshops: Direct air supply to assembly lines eliminates the need for enclosed spaces.
3. Special Environments
Agricultural and livestock farms: Maintain stable temperature and humidity to prevent heat stress in animals. Stadiums or waiting halls: A 30-40 air changes per hour ensures fresh air in crowded areas. Food processing areas: Water cooling eliminates the risk of CFC contamination and meets hygiene standards.

Specific advantages include:
1. Outstanding Energy Savings and Economical Performance
For a 2,000 square meter space, for example, 20 air coolers consume approximately 20 kW/h of electricity. A traditional 180-horsepower central air conditioner with the same coverage consumes 180 kW/h, resulting in a monthly electricity savings of over 48,000 yuan.
2. Quick Installation and Zero-Footprint Design
Flexible wall-mounted, rooftop, or mobile installation options eliminate the need for complex piping or dedicated equipment rooms.
3. Excellent environmental compatibility
Can operate with doors and windows open, maintaining safe ventilation (e.g., in chemical workshops)
No compressor vibration noise, improving workshop call clarity
