AIR SOLUTIONS TO GET A HOMOGENOUS MICRO CLIMATE

A good air distribution duct will determine a homogenous micro climate in your Greenhouse or Indoor- Vertical Farm. It goes further than just selling a hose with holes. At KE GrowAir it is all about dialogue, expertise and reliability. We don’t have a standard duct, components or end-products in stock, it will be customised and made for you.

GrowAir® ducts create a homogenous air distribution for cooling, heating, dehumidifying and ventilating. A patented outlet pattern provides a more homogenous micro climate in your greenhouse or Indoor- Vertical Farm. You will see better results at the horizontal and vertical temperature and humidity gradient, there are smaller compared to other air distribution systems. A more homogenous air distribution ensures a more uniform micro climate and growth pattern of your product, enabling more production in the entire facility.

WHY CHOOSE A GROWAIR DUCT SYSTEM?

1. Flexible and customised solutions
Solutions specifically customised to your project and designed to ensure homogenous air distribution and optimal micro climate.

2. Efficient air distribution
The system has a high inductive outlet pattern that provides a good mixture of the injected air with the air that is already in the growing area.
Due to the position and our hole pattern, you obtain a lower temperature in the crop of the plant.

3. Unique design
With this specifically developed duct for greenhouses we have found the right balance between the dynamic and static pressure.
This is why the air flow at the beginning and at the end of the duct is more uniform than in any other system.

4. Patent
The duct system has a uniquely designed, patented and highly inductive outlet pattern. This unique outlet pattern ensures a very good mixture of the injected air with the air that is already between the leaves and in the growing area.

5. Entrainment
Entrainment is an undesired parallel airflow along the air distribution duct in the direction of the airflow, which is usually created in air distribution ducts with only a normal hole pattern. Entrainment is a major cause of poor air distribution in greenhouses. Due to the slanted outlet, there are high air speeds and a shortage of air at the beginning of the air distribution duct and an excess of air at the end.

6. Less energy consumption
Due to the single duct concept and a balanced ratio between the selected ventilator and the air distribution duct, the power consumption of the ventilator is considerably less, resulting in lower energy consumption or a larger quantity of air supply.

7. UV-stabilised
The material is transparent or white polyethylene (PE) and is UV-stabilised [320 Kilo Langley per Year (KLY); 80 KLY is one year of UV in the Netherlands].
The thickness of the material is 150 or 180 micron. It is produced in three layers, resulting in a material that can optimally withstand cracking (breaking by continuous movements). 

8. Easy to mount
An additional advantage of a single hose is the easy mounting: you have to mount only a single duct and that will save you time. You don’t have to consider the second duct which will be inside the outer duct that can move with the installation. The weight is many times lower so that you can install a lighter suspension construction. When replacing the ducts, you have to pay only half the amount of environmental tax for transporting the discarded plastic

Vertical Farming and Indoor Growing

The growing world population and accompanying urbanization makes it necessary to come up with solutions which put less stress on arable soils in the world. Vertical farming and indoor growing holds the key. Vertical farming makes it possible to grow vertically. It is a simple way of growing crops and plants in different cultivation layers one above the other. This makes urban agriculture possible in, for example, empty office buildings in large cities such as Dubai, New York or Amsterdam. Vertical farming is also suitable in large greenhouses. In this fast growing market many companies look at LED light regimes for growth and hydroponic systems for optimal production. One other key feature in these systems is undervalued: a good micro climate and optimal homogenous air distribution and this is our high expertise at GrowAir. To distribute air and create a homogenous micro climate looks very simple and easy but is is a very complicated business where mistakes easily are made. With more than 30 years of knowledge we know how to distribute air in the best way.
 

For vertical farming and indoor growing we combine the strengths of KE Fibertec and KE GrowAir to benefit you with: 

* Flexible and customized optimal solutions

* Horticultural and optimal air distribution knowledge combined

* Homogenous air distribution in every corner, at every level of your vertical farm

* Fire approved materials

PERFECT GROWING CIRCUMSTANCES AND HOMOGENOUS MICRO CLIMATE  

Control of the internal climate in your indoor growing facility gives you influence over both the growth of your crops and the prevention of diseases and crop damage. The air movement must be homogeneous in the room so that no dry or damp spots arise. Because no project is alike, we choose for every project the best combination of air distribution system and fabric to meet your demands for the project. This ensures you to get the best homogenous air distribution and micro climate there is for optimal produce in the market.

We are able to combine the best parts of our two worlds: building climatization and horticulture. We create the perfect growing circumstances and micro climate with a full range of air distribution systems for any type of vertical farm or indoor growing facility.  

The KE-Low Impulse System is produced using round ducts (Ø), half-round (D)
or quarter round (½D) ducts. The air distribution principle for horizontal low impulse
systems is based on passive thermal displacement where the air is supplied at a lower
temperature in relation to the air in the room. 

The KE-Inject^® System is produced in the form of round (Ø), half-round (D)
or quarter-round (½D) ducts and is made of a coated, non permeable textile
material with groups of small holes in the duct surface. From a ventilation
technology perspective, the KE Inject System can be regarded as an active
high impulse system for mixing ventilation. The KE-Inject System, unlike
its low impulse counterpart, can be used for cooling, ventilation and heating. 

The KE-DireJet^® System is produced in the form of round (Ø), half-round (D)
or quarter round (½D) ducts and is made of a coated, non-permeable textile
material with rows of conical nozzles for 100% active and directional delivery. 
From a ventilation technology perspective, the KE-DireJet System can be regarded
as an active high impulse system for mixing ventilation. KE Fibertec is the only
distributor of textile ducts that offers five different nozzle sizes: Ø12, Ø18, Ø24,
Ø48 and Ø60 mm. 

The KE-Inject^® Hybrid System is produced in the form of round (Ø), half-round (D)
or quarter-round (½D) ducts and is made of a permeable textile material with groups
of small lasercut holes in the duct surface. The lasercut holes are placed in the same
patented hole design as with the KE-Inject System. From a ventilation technology
perspective, the KE-Inject Hybrid System can be regarded as a combination of active
high impulse ventilation and passive low impulse ventilation.

The KE-DireJet^® Hybrid System is produced in the form of round (Ø), half-round (D)
or quarter-round (½D) ducts and is made of a permeable textile material with rows of
conical nozzles for  partially active and directional delivery. From a ventilation technology
perspective, the KE-DireJet Hybrid System can be regarded as a combination of active high
impulse ventilation and passive low impulse ventilation. In a nutshell, the KE-DireJet Hybrid
Systems comprise low impulse ducts which are madeactive by using conical nozzles.

Furthermore there are 3 types of fabrics available to come up with the best solution for your project:

o GreenWeave® (with 7 permeability's)
o MultiWeave® ( with 5 permeability's)
o ZeroWeave® (with PVC Coating)

Finally all our solutions for an optimal homogenous air distribution will come with:

o Food grade and fire approved materials
o One of the 1600 RAL/Pantone colors
o Cradle2Cradle materials

Technology

Technologies make a significant difference in vertical farms 
New sensors, smart energy systems, and other technologies make growing more efficient. Just like the many people using smart devices and automation to make their homes more convenient, vertical farms are typically automated to control light, temperature, and water use. They allow farmers to optimize the conditions required for growing to produce the food and quality that consumers want most at the store. The very best facilities can regulate lighting, humidity, temperature and nutrient levels to maximise the growth of thousands of plants simultaneously so that the yield is maximised and cost is reduced.

KE GrowAir has developed and patented special air distribution hoses that provide a perfectly homogeneous air distribution in every corner of your vertical growing space and microclimate on plant level. We can create excellent air circulation even if you have many growing levels in your vertical farm. Our air treatment solutions are custom designed and wil customized to the size and shape of your vertical farm and specific crob. 

Vertical farming pushes the boundaries of a microclimate
Homogeneity is what should be striven for to ensure consistency in crob quality and quantity. Minimizing the differences in climate to which the plants are exposed allows for less variation in chemical profiles between, and within batches. This should be the golden rule in cultivation of crops that are grown for their compounds, as end-users and manufacturers should be able to rely on consistency. Batch after batch.

Together with our 40 employees and more than 30 years of experience in designing, advising and supplying a good climate and an optimal homogenous air distribution – provide a specific solution for your specific project. Today, air distribution systems are used in almost all applications - from industry to sports centre’s, office facilities, laboratories, food industry, horticultural sector and many other applications that require a good indoor climate. A important challenge is how to fit all the different parts in the Vertical Farm. 

But where to start as an individual company?
For (semi closed) greenhouses, vertical farming ore indoor facility we benefit you with:

* Flexible and customized climate solutions
* Horticultural and optimal air distribution knowledge combined
* Avoid entrainment and turbulence
* Uniform air distribution and temperature (vertical and horizontal)
* Microclimate on plant level
* Equal growth of crop from beginning to end and from low to high
* Higher air quantity
* Lower energy consumption
* Lower installation and disassembly cost
* Patented diffusion holes

To distribute air looks very simple and easy, but it’s a very complicated business, mistakes are easily made and how to integrate all these different technologies. With our 30 years of knowledge we know how to distribute air best.
