For decades, paper (cellulose) evaporative cooling pads have been the industry standard for poultry houses, pig farms, greenhouses, and industrial facilities. However, a new generation of plastic cooling pads is rapidly gaining popularity—and this is no coincidence. Service Life: 1–3 Years vs. 10–15 Years This is the most significant difference between the two materials. Paper cooling pads typically last only …

Plastic Evaporative Cooling Pads—a next-generation solution designed to outperform traditional cooling media, offering superior durability, enhanced performance, and smarter design. Plastic evaporative cooling pads operate on the same fundamental principle as paper pads but offer greater reliability. Water circulates from a reservoir to the top of the pad and flows down across the large surface area of ​​the plastic material. …

You Are Cordially Invited to Visit the WUSEN Booth at SIAVS 2026 in São Paulo, Brazil Dear Partners, We cordially invite you to visit the WUSEN booth at SIAVS 2026 (International Animal Protein Trade Show), taking place in São Paulo, Brazil, from August 4 to 6, 2026. As the most influential livestock industry exhibition in South America, SIAVS serves as …

Different seasons, weather conditions, and bird ages require different ventilation strategies. WUSEN air inlets feature an independent baffle design, allowing for precise control over intake volume and direction.     Equipped with adjustable flaps, these inlets enable farmers to regulate the volume of fresh air entering the poultry house. Whether you need maximum airflow during hot summers or minimal ventilation …

Cooling Efficiency Modern plastic evaporative cooling pads offer cooling efficiencies of up to 78–85%. High-quality plastic pads feature unique honeycomb or 3D mesh structures that maximize evaporative surface area, enabling an immediate temperature drop of 4–12°C depending on ambient conditions. Crucially, the cooling efficiency of plastic pads remains stable over the long term. Unlike paper cooling pads, which degrade and …

The farm odor control and purification system is a device or equipment for treating the malodorous gas produced in poultry. Its main purpose is to improve the breeding environment and reduce the negative impact of odor on the surrounding environment and human health. 1. Understand the source of farm odor The generation of malodorous gas in the farm is mainly …

Polyurethane (PU) air inlets boast exceptional resistance to UV radiation, corrosion, moisture, and aging. Even when subjected to prolonged extreme weather conditions and the harsh environment of a poultry farm, they remain free from deformation, cracking, rusting, or fading. The high-toughness PU material maintains its structural integrity and stability even after countless opening and closing cycles, while also offering superior …

In modern livestock farming, environmental control is an essential prerequisite for ensuring animal health, welfare, and productivity. Although exhaust fans—acting as the “engine” of mechanical ventilation systems—often garner the most attention, air inlets—serving as the equally vital “lungs”—are frequently overlooked. Even if the fans are appropriately selected, poorly designed or managed air inlets can still lead to drafts, uneven air …

May 18–20, 2026 — The 23rd China Animal Husbandry Expo (CAHE) and the 2026 China International Animal Husbandry Exhibition officially opened at the Western China International Expo City in Chengdu. WUSEN presented its comprehensive range of livestock environmental control equipment and customized facility-wide solutions, leveraging its exceptional technical prowess to unveil new possibilities for the industry’s future development. Focusing on …

I. Why Do Greenhouses Need Evaporative Cooling? High summer temperatures are the number one killer in greenhouse cultivation. When greenhouse temperatures exceed 35°C, the photosynthesis of most crops declines significantly; pollination is hindered, fruit quality deteriorates, and in severe cases, entire plants may even wither and die. Traditional ventilation and cooling methods can only lower the temperature to match that …

The principle behind evaporative cooling is that when water evaporates, it absorbs heat from its surrounding environment. As dry, hot air flows through a water-saturated cooling pad, the water undergoes a phase transition from a liquid to a gas (water vapor). This phase-change process directly extracts thermal energy from the air, resulting in a significant drop in air temperature—typically ranging …

Effective ventilation begins with proper air inlet design. It determines the location, velocity, and uniformity of the fresh air entering the poultry house. Side-Wall Inlets (Minimum Ventilation Mode) Primarily used during cold weather or the brooding period. These small, adjustable vents are installed high up on the side walls. When opened by negative pressure, they direct incoming cold air upward …
