Greenhouse Cooling Systems

Controlled Cooling, Maximum Efficiency with Evaporative Cooling Systems
Evaporative cooling systems, developed to eliminate the negative effects of high temperatures on agricultural production, are one of the fundamental components of climate control in modern greenhouses. With over 20 years of experience in climate systems and application engineering, Keyway offers evaporative cooling solutions tailored to every climate zone and crop type.

System Engineering: Balance of Humidity, Temperature, and Airflow
At Keyway, evaporative pad systems are not viewed solely as cooling tools; they are integrated into a complete system that also considers humidity and air circulation inside the greenhouse. From fan and pad placement to water circulation lines, drainage infrastructure, and automation controls, every detail is professionally engineered. Especially in large-volume glass greenhouses, evaporative pad systems are integrated with exhaust and circulation fans to ensure homogeneous temperature and humidity distribution throughout the greenhouse.

High-Quality Cooling Pads
The high-density cellulose-based evaporative pads used by Keyway absorb water quickly and evaporate it over a large surface area. This effectively lowers air temperature while preventing sudden humidity fluctuations that could negatively impact plant growth. Thanks to a special resin coating, the pads are long-lasting and resistant to UV rays and biological degradation. Available in different thicknesses and heights, the pads allow flexible application based on greenhouse type.

Automated Water Distribution and Control Systems
Evaporative systems are supported by fully automated water circulation units. Water tanks, filtration systems, distribution pumps, and water distribution channels placed above the pads ensure uniform water delivery across the system. With automation infrastructure, parameters such as operating duration, pump speed, and fan velocity can be optimized according to outdoor temperature. This minimizes energy consumption and keeps the greenhouse microclimate consistently within the desired range.

Solutions for Global Climate Conditions
Keyway’s evaporative cooling systems deliver high performance in hot and arid regions such as the Mediterranean, the Middle East, North Africa, South Asia, and South America. The engineering of each system is uniquely designed for the crop type, geographical conditions, and intended use of the greenhouse.

At Keyway, evaporative cooling is not just a product—it is a climate engineering solution. From design and installation to commissioning and technical training, Keyway stands by the grower throughout the entire process.
