Optimal growing conditions near the plant

The hoses can be placed under the gutters. This provides horizontal air movement, and creates optimal growing conditions near the plant.

Enerdes air distribution hoses for semi-closed greenhouse can also be hung in the top of the greenhouse. This mixes air in the entire space and provides even temperature distribution and a homogeneous humidity distribution on a big scale. The air hoses in the top of the greenhouses provide both horizontal and vertical air circulation.

Enerdes – experts in creating the perfect air quality in greenhouses.

Best air distribution performance

A perfect air distribution in the greenhouse is essential for your crop. Enerdes air distribution hoses ensure a continuous flow of air which is necessary to, for example:

  • Reduce diseases (Botrytis)
  • Reduce mold development
  • Improve distribution of humidity
  • Improve temperature distribution
  • Air mixing
  • Dry air introduction

Due to air hose ventilation, the air is distributed perfectly over the entire length of the hose. The result is a balanced growth of the crop and reliable yield rates.

No horizontal temperature differences

The perfect insulation of the double-layer air distribution hoses ensures that there are no horizontal temperature differences in the greenhouse. Both the horizontal and the vertical temperature gradient are much smaller compared to conventional air hoses.

This delivers the following advantages:

  • Even growth behaviour of the throughout the entire greenhouse
  • No cold spots
  • No local humidity buildup

Optimal growing conditions near the plant

The hoses can be placed under the gutters. This provides horizontal air movement, and creates optimal growing conditions near the plant:

  • Proven to improve plant health
  • Reduces humidity accumulation
  • Avoids the problems that come with stagnant air in a greenhouse

Enerdes air distribution hoses for semi-closed greenhouse can also be hung in the top of the greenhouse. This mixes air in the entire space and provides even temperature distribution and a homogeneous humidity distribution on a big scale. The air hoses in the top of the greenhouses provide both horizontal and vertical air circulation.

Tailor-made hole patterns for optimal puncture hole distribution

Enerdes double air distribution hoses can be provided with any desired pattern of holes:

  • Any length
  • Large availability of hole diameters from 4 to 50mm
  • Large availability of air distribution hose diameters from 100 to 1020mm.
  • Any hole pattern, linear and variable

But some combinations are more optimal for your greenhouse than others. We will help you find the best choice so that the air is evenly distributed throughout the entire air distribution hose.

We can even model your greenhouse, gutters and plants with computational fluid dynamics (CFD) and determine the theoretically most optimal puncture hole distribution.

Enerdes air distribution hoses are being used in the whole world

Lower minimum fan speed of Enerdes air hoses

The great advantage of the Enerdes air distribution hoses is that, independent of the fan speed, you have a perfect blowout over the entire length of the air distribution hose. This enables you to set a lower minimum fan speed for the times when less air movement is desired. This is a big difference compared to single layer air distribution hoses.

The lower fan speed saves energy and this is advantageous for the energy bill. It is the most environmentally friendly and the most economical solution for greenhouses.

Enerdes also supplies the fans and everything needed to power them up and control them. You can even control the speed of each fan or fan group separately, thus controlling the air circulation in different areas of the greenhouse in any desirable way. This may come in handy if for example you have areas for different plant growth stages or different plant densities.

Fewer diseases through perfect air movement

Stagnant air in a greenhouse is the source for plant diseases. By keeping the air in motion constantly, germs and diseases as well as molds get less chance to grow.

The perfect air circulation in the greenhouse which is created by the double-layer air distribution hoses, makes sure that there are less or no diseases occurring in the greenhouse.

Longest life time for double air distribution hoses

Through the controlled movement of air in the double-layer air distribution hoses, there is no turbulence or uneven air movement. This results in the following advantages:

  • More stable hose
  • Hose is subjected to less fatigue
  • Prolonged lifespan of the hoses
  • Very low replacement cost

In addition, the maximum UV-stabilization ensures that light does not affect the air distribution hoses in semi-closed greenhouse. Furthermore, special additives make sure that the hoses are sturdy and tear less easily.

Customization with your logo

Upon request, we can print your own custom logo on the hoses. We supply the hoses both in white and transparent.

Air distribution hoses: the perfect diameter

Through our years of experience and research, we can calculate exactly what hoses ensure perfect airflow in your greenhouse.

In the table below, L is a symbol for the length of the greenhouse. Next, look at the correct distance from the centre to the centre of the gutter (in meters).

Which diameter hose fits the best in your greenhouse layout?

  • Punched holes

End Caps

Enerdes delivers tailor-made end caps and can coat them if required. We can also provide them with stickers with your (company) logo’s. We often deliver them in combination with air distribution hoses.

End caps have three major advantages:

  1. Improved quality of center aisle plants
    Each end cap has four adjustable openings. This allows you to determine how much air is allowed to escape from each air distribution hose. The extra ventilation at the end of the air distribution hose increases the quality of your plants at the center aisle.
  2. Improved working conditions
    On a center aisle in a greenhouse, it is often hot due to the sun shining full on the concrete. An additional advantage of end caps is that the often hot concrete in the aisles is cooled by the air distribution hoses. This ensures better working conditions for your employees.
  3. A better look for your company
    Normally, air distribution hoses are often terminated by means of tie wraps. This often looks unkempt. The use of end caps gives a more professional look and can also be used for marketing purposes by using stickers for example.

Greenhouse CO2 Enrichment by Enerdes

For some greenhouses, an even distribution of introduced CO2 gasses is very important as well. Instead of opening valves that blow CO2 rich gasses into the greenhouses.

CO2 tubes can be connected to the valves. These smaller poly ducts with a diameter of most commonly ø50 mm, are usually about 50 m long and have small puncture holes over the tube, similar to air distribution hoses.

The pressure distribution along CO2 tubes is critical for the CO2 introduction around your plants. We manufacture these CO2 tubes as well and we can advise you what the best length, diameter and hole pattern is for your crop.

A complete air distribution system for greenhouses includes many other components besides the air distribution hoses. These are all supplied by Enerdes as well:

  • Greenhouse fan
  • End caps
  • End caps with adjustable opening
  • Suspension hangers
  • Suspension chain
