About Dalsem Complete Greenhouse Projects DALSEM - COMPLETE GREENHOUSE PROJECTS Dalsem is a leading greenhouse builder that develops complete high-tech greenhouse projects since 1932 that yield the highest quality and quantity of products in the shortest time. DALSEM AIR - SEMI-CLOSED GREENHOUSE Our latest technological development is the DALSEM AIR, Semi-Closed Greenhouse. A state of the art semi-closed greenhouse in the market to date. Dalsem designed the DALSEM AIR greenhouse to maximize plant and crop growth by optimizing the greenhouse climate conditions in a sustainable way while saving earth’s natural resources. Our DALSEM AIR greenhouse is more flexible to adapt greenhouse conditions than any other conventional or semi-closed greenhouse systems. DALSEM AIR SEMI-CLOSED SYSTEM (patented) The heart of the semi-closed greenhouse is our DALSEM AIR Semi-Closed System and an essential part of the energy-efficient climate control system. A solution that combines decentralized forced air ventilation and circulation to resemble natural airflow from above to the crop. By circulating and mixing greenhouse air with outside air or air from above the screens, optimal growing conditions are created inside the greenhouse. LESS ENERGY, LESS RISK, MORE PRODUCTION! Additionally, the decentralization of the controlled outside air intake facilitates growers to cool and/or dehumidify the greenhouse air in an energy-efficient way with no limitations if the screens are open or closed. By dosing CO₂ directly into the moving airflow, the distribution will be uniform. The DALSEM AIR Semi-Closed system will ensure that less ventilation is required and high carbon dioxide (CO2) levels can be maintained for a longer period of time. This will translate directly into a substantial production increase and reduction of energy costs. UNIQUE TO DALSEM The complete control of the design, manufacturing and execution of the project on-site is unique to our company. All parts of the greenhouse are manufactured in our Dutch factory. We are a greenhouse builder that can customize the greenhouse exactly to your needs to deliver a full functioning and operational greenhouse. In each horticultural project, we strive that the customer achieves the optimum yield. Training, management and consultancy to ensure the right conditions for growth, will make your project complete.
