Convection tubes or air distribution hoses allow for a better air distribution in your greenhouse. It is important for your plants that there is an even temperature and humidity distribution all throughout the greenhouse as well as that there is air movement around the plants. Our patented Double air distribution hoses allow for the best pressure and air development. Single air hoses are also available.
Greenhouse accessory suppliers use different terms for similar products. At Enerdes we prefer the term Air Hoses and for our optimized and patented product: Double Air Distribution Hoses. Below is a list that all refer to air hoses for greenhouses:
Convection tubes are plastic foil tubes made of polyethylene that can be filled with air. These tubes are installed in greenhouses in order to provide fresh air and air circulation to the crops. Some are unpunched for air transport. The tube foil can also punched in specific patterns to provide optimal air distribution and air circulation around the crops. The tubes can either be placed in the top of the greenhouse to provide heating and cooling in a very energy efficient and cost saving way. Or they can be placed under the crop gutters, in order to provide moving air around the plants and improve moisture concentrations. The convection tubes functions in the following way:
A convection tube system provides an energy efficient way of air ventilation and cooling and heating in a greenhouse. The poly convection tubing implements a uniform air distribution throughout the entire greenhouse and around all crops. It also causes air mixing which in turn ensures better CO2 balances and a homogeneous temperature distribution around all plants. This results in constant and reliable quality of crops.
The moisture balance or humidity levels in the greenhouse also improve when a proper convection tube system is installed in the greenhouse. This enhances crop quality and reduces the risk of mold or plant disease development.
Air distribution hoses can provide a constant flow of fresh air and thus eliminate stagnant air, improves humidity levels, removes dry and cold areas or hot and wet ones. This all results in a more consistent environment for your crops.
In conclusion, installing a proper air distribution hose system in your greenhouse will increase product quality and crop yield and save you energy as well as money. It is an environmentally friendly and a cost effective investment.
Two types of air hose foil are available, transparent and white. Both are available in varying material thicknesses. The punctore hole pattern can be adjusted on request or optimized to your specific application. The best choice depends on the greenhouse climate and the customers application.
Air hose Type: | Transparent | White |
Greenhouse Location | Top | Bottom |
Function | Crops will still receive 58 % of sunlight | Crops receive reflected sunlight |
Maintenance | Easy to see when hoses need to be replaced | Harder to see, depending on greenhouse climate. Standard is once every year?? |
Heat capacity | Higher | Lower |
Other suppliers do not have the right to produce our patented DADH’s and can only deliver single air hoses that have a worse performance and are less energy efficient. They are mainly based in USA. Enerdes supplies air hoses globally, including the United States and Canada:
