A striking project is nearing completion: the screen installation at the new Florensis company in Dinteloord, the Netherlands. It is not the largest project ever realised by Holland Scherming, but it is a complex project, technically and logistically.
Florensis will cultivate young plants at the Nieuw Prinsenland business location in Brabant. This will be done with a minimum use of energy and crop protection products. The greenhouse has an area of approximately 60,000 square metres and the production hall is 5,400 square metres.
Minimum truss height
From a technical point of view, the screen installation is a big challenge for Holland Scherming. The installation with three unique screens on top of each other is brought together within a truss with a height of only 66 cm. This requirement even made it necessary to mount the type of screen motor with the smallest possible housing. Using the Smart Spring system, Florensis is able to assemble each screen into a small package.
The complexity of the screen, three on top of each other, combined with the tight planning required an unusual solution from Holland Scherming. That is why three shifts - a total of 20 employees - worked on the project at the same time. This was done from seven platforms, supported by two Merlo telescopic handlers.
Eye for details
The attention to detail is striking. There was a lot of consultation with the greenhouse builder beforehand in order to arrive at a beautifully integrated installation. Holland Scherming has worked everything out down to the smallest detail. For example, custom-made metal flashings (white powder coated steel plates) were used to make the greenhouse light and energy proof at the location of the horizontal systems at the facades. The side finishes of the facade screens are also neatly sealed with flashings. The motors are nicely concealed and protected against moisture and dirt.
The numbers appeal to the imagination: for example, 12,000 Smart Springs have been incorporated into the installation, 87,000 stainless steel wire clamps and 250,000 metres of steel wire. There will soon be a total of 181,000 square metres of cloth at the top of the greenhouse. Supported by 1,000,000 metres of polyester wire.
In addition to the usual screen strips for the screen plates, screen plates have also been mounted through the (inner head) facades, for example. The truss is also prepared with axle bearing supports and chimney supports.
Despite the short implementation time and the high degree of difficulty, Holland Scherming has carried out the project perfectly on schedule. This is partly due to the good coordination from Florensis and the cooperation between the construction partners involved. Construction drawings were exchanged with the greenhouse builder at an early stage in order to achieve optimum integration of the greenhouse and the system. As a result, it turned out that everything was perfectly in line with each other during construction.
