"These droplets evaporate rapidly, lowering air temperature and raising humidity without wetting the plants."

This rapid evaporation stabilizes the vapour pressure deficit (VPD), a critical factor for minimizing plant stress and optimizing growth potential. The modular design allows growers to adapt the system for different greenhouse sizes and climate conditions. High-pressure fogging can operate independently or in combination with pad systems, ensuring flexible adaptation to localized conditions within the greenhouse.
Pad cooling for efficient airflow management
Pad cooling works on a similar principle of evaporative cooling, but through a different mechanism. "Air is drawn through wetted pads, and as part of the water evaporates, the air is cooled and humidified," he explains. "Our water distribution ensures even wetting across the pad surface, which enhances cooling efficiency while reducing energy use."
LUBING GreenTec Plastic Pads are designed for durability and performance. Their material and surface structure maintain optimal water flow, resist UV degradation, and allow cleaning with high-pressure washing, extending their service life compared to traditional paper pads.

System integration and climate automation
"Both the Fogging- and Pad-Systems integrate seamlessly with climate computers, which process temperature and humidity sensor data to trigger activation automatically," he notes. "Our systems also support zone control, so different areas of the greenhouse respond independently to local conditions. This enables growers to coordinate fogging or pad cooling with ventilation, shading, and CO₂ delivery for optimal results."
According to Alexander, durability is central to LUBING GreenTec's engineering approach. "Components are made from stainless steel to resist corrosion, while modular pump assemblies and clip-profile pad mounts simplify servicing." He adds that routine checks of filters, nozzles, and pumps prevent wear-related failures, and plastic pads tolerate pressure washing without damage. "In practice, growers report that our systems require relatively little maintenance, and our technical support helps minimize downtime."

LUBING GreenTec Pad System
Proven outcomes in greenhouse operations
Several case studies highlight the systems' effectiveness. In a tomato greenhouse in Mexico, the installation of a LUBING GreenTec Fogging-System under extreme heat conditions led to a yield increase of approximately 25%, while operational costs fell by 15–25% compared to previous systems. In Europe, flower growers in Germany, Italy, and Switzerland have successfully maintained optimal humidity ranges (50–80%) throughout the growth cycle, improving plant quality and simplifying climate control integration.
Sustainability and resource efficiency
Sustainability is a growing concern in greenhouse management. Alexander emphasizes that their high-pressure Fogging System maximizes water evaporation, reducing water use compared to conventional low-pressure systems. Additionally, the LUBING GreenTec Plastic Pad-System is made from recycled materials and features low-pressure loss, which reduces fan energy requirements.
