Dalsem AIR Semi-Closed System

Including CO2 dosing directly into moving air

A new era for Semi-Close greenhouse growing!
The Dalsem AIR Semi-Close Greenhouse Solution with the Dalsem AIR Semi-Closed System adds new dimensions to the current approaches for greenhouse growing.

• The perfect symbiosis of knowledge, technology and data control.
  No resources are wasted, water is re-used and energy consumption is kept to a minimum.
  Yield and production quality are optimized due to the use of Data Driven Growing without need of a highly experienced grower.
• The Data Driven Growing Strategy will improve yield, avoids human error and therefore will attract more capital to the greenhouse industry.
• Sustainability due to our solution and the introduction of the Dalsem AIR Semi-Closed System.
  Your greenhouse will generate more production compared to current greenhouses, in some cases up to 10%, whilst saving energy (up to 20%) and CO2.

NEW: CO₂ DOSING (PATENT PENDING)

Dalsem has developed a new method for CO₂ dosing, which is more effective than any other CO₂ distribution method used in horticulture today. From the distribution point in the greenhouse, a pipe system is installed underground and leads upwards over the columns to the Dalsem AIR Semi-Closed System. By dosing the CO₂ in front of the fan blades, the CO₂ mixes directly with the air blown from the Dalsem AIR Semi-Closed System and evenly distributes the CO₂ in the greenhouse. 

Inserting CO₂ into flowing air is perfect for the plant photosynthesis. The moving air reduces the boundary layer resistance and increases the efficiency of photosynthesis, whilst bringing CO₂ to the stomata. An additional advantage is the distribution of the CO₂ from top to bottom in the greenhouse, contrary to other methods currently available. By using this method, the CO₂ accurately reaches the stomata or leaf pores of the plant and is absorbed most effectively.
