Fan & Pad Polyhouse

Fan & Pad Polyhouse is a fully climate control greenhouse system that uses forced-air evaporative cooling — exhaust fans on one wall and wet cellulose cooling pads on the opposite wall — to hold temperature and humidity inside a tight, crop-favourable range regardless of the outside weather. It is one of the most effective fan pad polyhouse designs for high-value crops that cannot tolerate the temperature swings of a naturally ventilated structure.

Key Features

• Wet-wall cooling pad system with continuous water circulation for evaporative cooling

• Wall-mounted exhaust fan bank that draws air across the pads for controlled airflow

• Precise temperature and humidity control, independent of outside weather

• GI pipe/truss framework with UV-stabilized film or polycarbonate covering

• Thermal/shade screens for additional heat and light management

• Fogging and misting compatibility for extra humidity control

• Automated control panel for fan cycling and pad wetting

• Insect-proof netting and drip irrigation/fertigation compatible

Benefits of Fan & Pad Polyhouse

• Maintains a stable internal microclimate even in peak summer heat

• Enables cultivation of high-value, climate-sensitive crops round the year

• Higher yield and quality compared to naturally ventilated structures

• Reduces crop stress and disease pressure from temperature and humidity swings

• Supports precision fertigation for consistent nutrition

• Extends the growing season beyond what open-field or natural ventilation allow

• Well suited for export-quality produce and protected nurseries

Suitable Crops

Fan & Pad Polyhouse is commonly suitable for:

• Capsicum

• Cherry Tomato

• Cucumber

• Exotic Vegetables

• Cut Flowers (Rose, Gerbera, Carnation)

• Tissue Culture Hardening and nursery plants

Crop suitability depends on the local climate, cultivation method and market requirements.

Fan & Pad Polyhouse Structure

A typical Fan & Pad Polyhouse consists of:

Fan & Pad Polyhouse Design

The design and dimensions of a Fan & Pad Polyhouse should be selected according to:

• Available land area and orientation for correct airflow direction

• Crop type, height and canopy density

• Peak outside temperature and humidity in the region

• Required fan capacity and pad area

• Power supply and backup availability

• Irrigation and fertigation requirements

• Farming budget

A properly engineered, site-specific design helps ensure correct fan-pad sizing, structural strength and long-term performance.

Fan & Pad Polyhouse Cost

The cost of a Fan & Pad Polyhouse depends on its span and gutter height, number and capacity of fans, pad area and material, covering (film or polycarbonate), automation level, irrigation, fertigation, and site conditions.

For an accurate price, the project should be evaluated according to the required area, crop and level of automation.
