Greenhouse Cooling System | Fan & Pad System

Our greenhouse fan and water curtain cooling system provides highly effective evaporative cooling and forced negative-pressure ventilation for commercial agricultural structures. The system is composed of high-efficiency wet cooling pads, a dedicated water circulation supply system, heavy-duty exhaust fans, and installation accessories. By drawing warm outside air through water-saturated cooling pads, the system rapidly lowers internal temperatures while humidifying and purifying the incoming air, ensuring a optimal microclimate during hot summer months.

Core Advantages & Structural Features

• Complete Evaporative Cooling Architecture Consists of wet cooling pads, water pumps, distribution pipes, water return troughs, and heavy-duty negative-pressure exhaust fans working in sync to create rapid air exchange and thermal reduction.

• Optimized Placement & Anti-Shading Layout Designed with wet cooling pads installed along the north wall and exhaust fans positioned along the south wall. This strategic orientation prevents the pad frames from shading crops, ensuring maximum natural sunlight exposure.

• Winter Insulation & Protection Options To maintain interior warmth during cold seasons, protective outer layers—such as external plastic film, sliding windows, or rack-driven outward-opening windows—can be installed outside the wet curtains to seal out cold drafts.

• High Cooling Efficiency & Air Purification Delivers significant temperature drops through natural water evaporation while simultaneously filtering dust particles and increasing relative humidity inside the greenhouse.

• Forced Negative-Pressure Ventilation High-volume exhaust fans pull large quantities of hot, stagnant air out of the greenhouse, maintaining constant fresh airflow, preventing heat pockets, and lowering disease risks.

Primary Applications

This fan and water curtain system is ideal for:

• High-Temperature Regional Agriculture: Essential cooling for commercial multi-span greenhouses operating in hot, dry climate zones.

• Temperature-Sensitive Crop Production: Protecting flowers, tomatoes, cucumbers, and leafy greens from high heat stress.

• Livestock & Nursery Facilities: Providing controlled air exchange, temperature reduction, and air purification for animal husbandry and plant propagation.
