Evaporative Wet Pad & Fan Cooling System For Greenhouse & Poultry House

What is a Wet Pad & Fan Cooling System?

A Wet Pad & Fan Cooling System (also known as an evaporative cooling system) is a highly efficient, large-scale climate control solution designed for agricultural and industrial environments. It consists of two main components: heavy-duty industrial exhaust fans installed on one side of the building, and porous evaporative cooling pads installed on the opposite wall. This integrated system provides continuous air exchange and rapid temperature drops, making it the industry standard for cooling large, open spaces where traditional air conditioning is too expensive to operate.

Working Principle

The system utilizes the natural physical phenomenon of water evaporation to absorb heat, operating on a negative pressure principle:

Air Exhaust & Negative Pressure: The powerful industrial exhaust fans pull hot, stale, and humid air out of the building. This creates a negative pressure zone (vacuum effect) inside the structure.

Outdoor Air Intake: Because of the internal negative pressure, hot and dry outdoor air is forced to enter the building through the wet cooling pads on the opposite wall.
Evaporative Cooling: As the hot air passes through the constantly wetted pad media, the water evaporates, instantly absorbing the sensible heat from the air.

Cool Air Distribution: Fresh, filtered, and significantly cooler air is continuously drawn into the facility, lowering the internal temperature evenly.

System Benefits & Advantages

Maximum Energy Savings: Consumes up to 80% less electricity than compressor-based HVAC systems because it only powers a simple water pump and exhaust fans.
Eco-Friendly Operation: Uses zero chemical refrigerants or harmful gases. It cools purely through natural water evaporation, making it safe for crops, livestock, and workers.

Rapid Temperature Reduction: Highly effective in hot, dry climates, capable of dropping internal temperatures by 5°C to 15°C depending on ambient humidity.
Improved Air Quality: Continuously flushes out dust, odors, and stale air, replacing it with fresh, filtered, and oxygen-rich outdoor air.
Low Maintenance Costs: Simple structural design means fewer mechanical parts to break, lowering long-term repair and replacement costs.

Target Application Areas

Commercial Greenhouses: Maintains the ideal microclimate for high-value agriculture, floriculture, and hydroponics. It prevents heat wilting and stabilizes plant growth cycles.

Evaporative Wet Pad & Fan Cooling System For Greenhouse & Poultry House 4

Poultry & Livestock Farms: Vital for poultry houses, chicken coops, and pig barns. It prevents catastrophic heat stress, lowers animal mortality rates, and boosts production yields.
Industrial Workshops & Warehouses: Provides cost-effective cooling and ventilation for large manufacturing facilities, logistics hubs, and garment factories.

Types of Evaporative Cooling Pads

Categorized by Material

Kraft Paper Cooling Pads (Cellulose): Made from premium imported wood pulp kraft paper treated with resin. They offer exceptional water absorption, cross-fluted structure for maximum evaporation surface, and the highest overall cooling efficiency.

Plastic Cooling Pads: Made from high-quality polymer plastics. They feature an exceptionally long operational lifespan, high resistance to algae growth, and are highly corrosion-resistant. They can be easily washed and pressure-cleaned, making them ideal for harsh environments.

Categorized by Flute Height (Wave Height)

7090 Type (7mm Flute Height): The most popular and widely used standard model. The 7090 configuration provides the perfect balance between airflow resistance and water-to-air contact area, delivering highly stable cooling performance for most agricultural applications.
5090 Type (5mm Flute Height): Features a denser wave structure with a 5mm flute height, which significantly increases the total evaporation surface area. It delivers maximum cooling efficiency in space-restricted setups or specialized industrial climate control systems.
