The DLI reflectors are manufactured to have the highest possible total reflectance at all wavelengths from 400 to 700 nm giving excellent PAR rendition. The integrated hemispherical reflectance is over 95% with an absence of iridescence colours in the louvre. The DLI reflectors are made from an electrochemically brightened high purity aluminium substrate coil, and start with an anodised base coat which gives a hard support to minimize abrasion damage. The material is then treated under vacuum with specially developed processes to maximise coating adhesion and is vacuum coated with a super pure reflection layer of 99.99% pure aluminium. These reflection layers are overlaid with a dual layer oxide system tuned for maximum visible reflection enhancement. This serves to increase the overall reflectivity provided by the metallic layers and adds protection against damage.

Mixing vessel or injection unit The Dosifeed is a mixing vessel or injection unit that can be used to prepare and pump feed water to your crops. The Dosifeed is available in different capacities and can be controlled by various computer systems. Version As standard, the Dosifeed is equipped with a stainless steel frame and a work floor of galvanised grids. The Dosifeed can be equipped with a mixing vessel, in which the A and B fertiliser solutions are accurately administered by means of a number of dosing pumps. When many different feed solutions have to be prepared, the A and B solutions can be injected into a mixing chamber equipped with a static mixer. An advanced EC and pH control system ensures the reliable dosage of the required fertilisers. The water is filtered through a sand filter that rinses fully automatically, or through a self-cleaning filter. For operational safety, an extra fine filter with a throughput of 130 microns is applied. An EC pre-control system can be applied for the mixing of drain water (which has been disinfected) to ensure the pre-set and regular supply of drain water. The Dosifeed can process various types of fertilisers into the desired nutrient solution. Nowadays, solid fertilisers are often mixed with premixed fertilisers in big bags. When liquid fertilisers are processed the A and B vessels can easily be filled using the Flowfeed.

One application, twice the protection BUGLINE DUO is the first release system on the market to introduce two species of predatory mite in a single application. The combination of two predatory mites in the same product thus provides protection against several types of pest in a single application for an optimal efficacy of the crop protection programme. This product requires fewer applications and less time to install, while guaranteeing perfect dosing with no wastage and no need for specific training. DUO: exclusive combination of two predatory mites in the same product. The BUGLINE DUO innovation contains two different species of predatory mite with complementary actions. This exclusive combination in the same release system aims to protect crops from several pests with a single application. The two species are packaged separately in alternating sachets for an even distribution. BUGLINE: an easy-to-install pre-dosed strip. The BUGLINE DUO system consists of a succession of sachets joined together to form a strip. The predatory mites are distributed in the sachets at a constant dose and alternate with perfect regularity. Thus, when installing the strip, a uniform and regular dose is automatically ensured without having to worry about distributing the products. Since the paper used in Bugline has a certain water resistance and the exit holes for the predatory mites are underneath, Bugline can be used with standard irrigation systems that water the plants from above. CRS sachets: extended efficacy. BUGLINE DUO sachets contain CRS technology. This technology ensures that each sachet constitutes a mini-breeding hub of predatory

One application, twice the protection GEMINI DUO is the first release system on the market to introduce two species of predatory mite in a single application. The combination of two predatory mites in the same product thus provides protection against several types of pest in a single application for an optimal efficacy of the crop protection programme. This product requires fewer applications and less time to install, while guaranteeing perfect dosing with no wastage and no need for specific training. DUO: an exclusive combination of two predatory mites in the same product. The GEMINI DUO innovation contains two different species of predatory mite with complementary actions. This exclusive combination in the same release system aims to protect crops from several pests with a single application. The two species are packaged separately in adjacent sachets. GEMINI: an easy-to-install protection system. The GEMINI system consists of two sachets joined together to form a roof. Each species of predatory mite is distributed in the sachets at a fixed dose. Thus, when the Gemini sachets are installed, an even ratio between the two species is guaranteed. Due to the roof shape of the Gemini sachets and since the paper used has a certain water resistance and the exit holes for the predatory mites are underneath, Gemini Duo can be used with standard irrigation systems that water the plants from above. CRS sachets: extended efficacy. GEMINI DUO sachets contain CRS technology. This technology ensures that each sachet constitutes a mini-breeding hub of predatory mites. They progressively leave the sachet over several weeks, thus providing continuous crop protection.

New: Dynamic pull wire! The load on the pull wires of screen installations is increasing: installations are becoming larger and screens are opening and closing more and more often to create the perfect climate at any time of the day. H.N.T. The New Cultivation method has made a major contribution to this. We have developed a pull wire that is suitable for this use: Dynamic pull wire! After an extensive test period, it has been shown that the Dynamic pull wire can withstand up to 10 times more screen movements and can therefore last up to 10 times longer than the traditional pull wire. That makes it the ideal pullwire for installations with intensive screen use.

Large-scale e-boilers are increasingly being used as a sustainable alternative to boilers and CHPs in industrial processes. They use excess, low-cost electricity from wind and solar power to generate heat, contributing to “peakshaving” and relieving stress on the power grid. Some e-boilers can switch on and off quickly, making them suitable for providing emergency power and stabilizing the power grid. This offers companies an additional revenue model and shortens the payback period. Companies must maximize peakshaving and flexibility to create a profitable and sustainable system. This power can be traded in various energy markets. Centrica Business Solutions offers expertise to help with this. Would you like to know more about the possibilities of a e-boiler?

The ongoing development in greenhouse construction is also visible in the work by Verkade Beton. The incorporation of robotics is a development with large consequences for the flatness of a concrete floor. Also the upcoming of different cultivations demands a larger diversity of solutions in concrete floors. With almost 4 million square metres of experience we know what we are talking about. A high grade of flatness, with minimal puddle formation, and evenly watered plants. With this experience we are able to advise you about the number of gutters, the slope and the number of drains necessary. Together with you we decide upon the optimal concept per project, based on your cultivation and the size of your company. We know our business, which is important as the concrete floor is one of the most important parts in greenhouse building. The scale of our organisation is a guarantee for our work. We handle around 20 hectares per year, and whether we have projects of 500 m2 or 30,000 m², we still remain flexible in the cooperation with other suppliers and the construction crew.

In the greenhouse horticulture sector, electric boilers are often used for greenhouses heating. By using electric boilers in the imbalance market, greenhouse horticulture companies can benefit from lower electricity prices when there is a surplus of renewable energy.
