Manufactured by:Dalsem based inDen Hoorn, NETHERLANDS
The roof of a Venlo greenhouse is self-supporting and is made from aluminium. The aluminium box gutter is a structural element. The design takes account of the fact that a greenhouse roof cleaner and/or a repair shuttle can travel through the gutter and that a service rail can be attached at the end of the gutter. The gutter collects rainwater and feeds it down the slope towards the gable ...

Water is one of the most vital ingredients for growing plants. In order to create optimal growing conditions, it is of the utmost importance that each crop receives the right amount of water containing the right amount of fertiliser at the right time. Hence, irrigation is an essential part of the cultivation ...

Ventilation is an important factor in maintaining the greenhouse temperature at the ideal level for the vegetables, flowers or pot plants. Depending on the desired ventilation capacity for your specific crop, there are various ...

In crop production, it is important to ensure that there is enough carbon dioxide (CO2) in the air since that is essential for photosynthesis and hence for plant growth. CO2 is generated whenever the boiler is in operation since it is contained in the flue ...

In the production of vegetables, flowers and pot plants, it is important that the temperature can be regulated day and night and that the heating system has sufficient capacity. Furthermore, it is important to create a homogeneous greenhouse climate without any cold spots. Water heated in the heating system is transported through pipes to the areas where heat is required. The heat warms the air ...

Fresh water is a scarce resource in many parts of the world. Water storage is essential for every horticultural company, whether in the form of rainwater storage, drainage water storage or the storage of recirculation water, since sufficient irrigation water must be available round the clock. It is also important to create a closed-loop cultivation system which allows the water to be ...

In the design phase, there are extensive discussions with the customer and, if relevant, their advisors to determine all the relevant greenhouse requirements and design parameters. Wind, snow load, elevation, crop type, cultivation method, the customer’s specific needs and local rules and regulations are just some of the factors that can influence the design and construction of a ...

Decontamination of drainage water is an important operational process in every greenhouse. Since the irrigation water is fundamental to crop growth, it must be of a high quality. Decontamination must provide sufficient protection against the spread of harmful microorganisms such as bacteria, viruses, moulds and nematodes in the recirculation of drainage water since many such microorganisms can ...

The application of light-emitting diodes (LED’s) as potential source for assimilation lighting in greenhouse production systems opens up a range of new possibilities. LED’s produce light in a very narrow wavelength range and do not directly emit heat radiation. The heat which is produced by LED’s due to their limited energy conversion efficiency, can be drawn away via convective ...

If the climate is both hot and humid, mechanical cooling is an option. In this case, electricity is used to cool water which is then transported to, and passed through, heat exchangers. This reduces the relative humidity which in turn reduces the temperature of the air in the ...
