VIDEO OF COOLING PAD

PRODUCT INTRODUCTION

Our greenhouse cooling pad is made of water absorbing kraft paper. It boasts a series of superior quality, such as strong hydroscopicity, high wet stiffness, corrosion resistance and long usable life etc. It absorbs the water naturally and the water absorbing capacity is 60-70mm/5min or 200mm/1.5h. The cooling efficiency is by up to 80%. Our greenhouse cooling pad no surfactant and harmful chemicals like phenol and no harmful to health during installation and application. It belongs to green and environmental products, meanwhile, it has approved "RoHS" certified.

1. What is a Greenhouse Cooling Pad?

A greenhouse cooling pad is a climate control system designed to reduce the internal temperature of a greenhouse during hot weather. Cooling pads work through a process known as evaporative cooling, where warm air is passed through a wet pad, and as the air evaporates the water, it cools the air before entering the greenhouse. The cool, moist air helps to maintain ideal growing conditions, especially in regions with high temperatures.

2. Material Composition 

Greenhouse cooling pads are typically made from corrugated cellulose paper or aspen wood fibers, which are designed to hold water and provide a large surface area for air to pass through. Some newer models use synthetic materials like PVC, which are resistant to decay and longer-lasting.

5. Core parts of the cooling pad

The effectiveness of cooling pads depends on their structure and core components. Here are the key parts:

Cooling Media (Pads)

These are typically made of cellulose, wood fibers, or synthetic materials. They are designed to absorb water and create maximum surface area for air to pass through.

Water Distribution System

 This is responsible for evenly distributing water across the cooling media. It ensures that the pads remain moist and effective in cooling the air.

Frame and Housing

The structure that holds the pads in place and ensures they remain secure. Typically made of durable metal or plastic.

THE SCIENCE BEHIND EVAPORATIVE COOLING

Evaporation requires energy in the form of heat. As the water evaporates, it absorbs heat from the surrounding air, lowering the air's temperature. This is why cooling pads are so effective in reducing internal greenhouse temperatures, especially during dry, hot weather.

  • Warm air is drawn into the cooling pads, usually via an exhaust fan system.

  • The wet surface of the pads evaporates the water, which cools the air.

  • The cooled air enters the greenhouse, lowering the internal temperature.

ADVANTAGES OF THE COOLING PADS   

Greenhouse wet pads offer several advantages over other cooling systems, such as air conditioning or misting systems.

Our greenhouse cooling pads wet curtain pads are widely used in film and glass greenhouses for their excellent properties, we have served many regular customers, they often buy the greenhouse cooling pad from us.

1. High efficiency

The unit can generally reach 4-13C, and the cooling can reach 4-15C in hot and dry areas, and the rapid cooling effect can reach 90%-97%.

2. Energy saving

low power consumption, a group of machines only 1 degree of electricity per hour,

3. Environmental protection

no compressor, no refrigerant, no pollution, low noise.

4. Health

Constantly provide fresh and clean air and increase the oxygen content of the air.

5. Save money

Installing wet curtain + fan in the same area is 2/5 of the total investment in central air conditioning.

6. Simple

easy to install, less maintenance, convenient operation, no need for professional maintenance.


APPLICATION OF THE COOLING PAD   

Greenhouse wet pads are used in a variety of agricultural applications. They are most commonly found in:

1. Commercial Agriculture

Large-scale growers use these pads in conjunction with climate control systems to maintain precise temperature and humidity levels.

2. Research and Laboratory Greenhouses

Maintaining a stable microclimate is key in experimental setups.

3. Horticultural Greenhouses

Cooling pads are perfect for floriculture and ornamental plants that need cool, moist air.

4. Urban Rooftop Greenhouses

In city environments where ambient temperatures can be extreme, these systems offer a compact solution for regulating heat.

FACTORS TO CONSIDER BEFORE INSTALLATION

  • Water Quality: Hard water can clog pads.

  • Airflow: Must be uniform for best performance.

  • Humidity Levels: In very humid areas, the cooling effect can be reduced.

  • Pad Maintenance: Algae and scale buildup need to be cleaned regularly.

FAQS OF GREENHOUSE COODING PAD

1. Are cooling pads safe for all plant types?

Yes, but ideal for crops that thrive in humid, cool conditions.

2. Can I build a DIY cooling pad system?

Yes, though commercial systems are more reliable and durable.

3. What’s the best type of pad for extreme climates?

Thicker cellulose pads paired with powerful fans work best in hot, dry regions.

4. How do cooling pads help with humidity?

Cooling pads not only lower the temperature but also increase the humidity inside the greenhouse. This is particularly beneficial for plants that thrive in high-humidity environments. The evaporative cooling process releases moisture into the air, balancing both temperature and humidity levels.

5. How long do greenhouse cooling pads last?

The lifespan of a cooling pad depends on the material used and how well it is maintained. High-quality pads made from cellulose or synthetic materials can last anywhere from 3 to 7 years, but regular maintenance is essential to prolong their lifespan.
