Description
Multi Span Greenhouse with Pad and Fan Cooling System for Hot Climate
Product Overview

The Wellgain WG-MSC-7000 is purpose-engineered for greenhouse operations in hot climates where excessive temperatures threaten crop health and productivity. This multi span greenhouse integrates an industrial-grade evaporative pad-and-fan cooling system that actively reduces internal temperatures by 5-10°C below ambient conditions, creating a favorable microclimate even during peak summer heat.

The cooling system operates on the principle of evaporative cooling: high-efficiency axial fans draw outside air through water-saturated cellulose cooling pads mounted on one end wall, causing water evaporation that absorbs heat and delivers cooled, humidified air throughout the greenhouse. Exhaust fans on the opposite end maintain consistent airflow, ensuring uniform temperature distribution across the entire growing area.

Combined with a shade screen option and reflective roof covering, the WG-MSC-7000 enables successful crop production in regions where outdoor temperatures regularly exceed 40°C. This system is particularly valuable for tomato, cucumber, pepper, and leafy green production in Middle Eastern, African, South Asian, and Australian growing conditions.

Factory Strength
Climate Engineering

We calculate cooling requirements using local climate data (temperature, humidity, solar radiation) to size pad area and fan capacity precisely for your location.

Energy Optimization

Our fan selection prioritizes energy-efficient models with EC motors, reducing electricity consumption by up to 40% compared to standard AC fan motors.

Water Management

Recirculating water system with auto-fill and bleed-off minimizes water consumption. Compatible with water treatment systems for hard water areas.

Turnkey Installation

We supply complete systems with pre-cut pads, pre-wired fan panels, pump station, and detailed installation guides for straightforward on-site assembly.

Application Cases
Date Palm Nursery – UAE

15,000 sqm cooling greenhouse for date palm tissue culture acclimatization. Pad-and-fan system maintained 28°C while outside temperatures reached 48°C. 95% plantlet survival rate achieved.

Tomato Production – Qatar

30,000 sqm greenhouse with evaporative cooling producing premium tomatoes for local market. Year-round production reduced import dependency by 40%.

Hydroponic Lettuce – Saudi Arabia

12,000 sqm NFT hydroponic greenhouse with pad-and-fan cooling. Produces 5,000 heads of lettuce daily in desert conditions with 90% less water than field farming.

Frequently Asked Questions
How effective is pad-and-fan cooling in humid climates?

Evaporative cooling is most effective in dry climates. In humid regions (RH >70%), the temperature reduction is typically 3-5°C. We can design hybrid systems with mechanical cooling for high-humidity locations.

How often do cooling pads need replacement?

Cellulose cooling pads typically last 3-5 years with proper water treatment. We recommend annual cleaning with mild acid solution to remove mineral deposits and algae.

What is the power consumption of the cooling system?

A typical 10,000 sqm greenhouse cooling system consumes approximately 15-25 kW during operation. Exact figures depend on fan specification, greenhouse dimensions, and target temperature reduction.

Can this system be retrofitted to an existing greenhouse?

Yes, pad-and-fan systems can be added to most existing multi span greenhouses. We conduct site assessments to determine feasibility and recommend necessary structural modifications.
