Finding synergies between dehumidification and hermetic screens As energy prices continue to fluctuate and sustainability targets tighten, greenhouse growers are increasingly turning to advanced climate-control technologies to reduce energy consumption. This article highlights two of these technologies, modern dehumidification systems and hermetic screens, and how they work together to create a more stable, energy efficient greenhouse climate.
After discovering that a traditional, porous energy screen created too much variation in the greenhouse climate, the grower switched to a hermetic Phormium screen — a change that immediately improved climate uniformity and allowed full benefit of the system's latent-heat recovery. "Combining a hermetic screen with our dehumidification system still yields the best results," says grower Wim Pijl, who recently upgraded to a new Hermetic Clear screen in anticipation of rising energy-efficiency demands.
Why this matters: This matters when it gives operators a clearer way to manage water, nutrients, and root-zone risk. That kind of control usually improves both resource efficiency and crop consistency.
Frequently Asked Questions
Why do retrofit and environmental-control choices matter so much?
Because these decisions affect every crop cycle that follows. A better control strategy can improve consistency and efficiency, while a poor one can lock in operating drag.
What should operators focus on when reading design or retrofit stories?
They should focus on what changed operationally: better climate stability, lower energy use, improved crop balance, easier labor, or cleaner control over inputs.
