Making unpredictable climatic conditions predictable: that is possible with a climate control system from Hamelink Koeling. For entrepreneurs in greenhouse horticulture, we develop systems that optimize the growing conditions for your crops. The climate is changing. Temperature extremes in the summer are becoming more frequent. Not an ideal situation for your crops. The right cooling or climate control system is the solution. An efficient solution: coolers with integrated heating if desired maintain temperature and relative humidity at the desired level.

The GenaDome PRO is a resilient, fully enclosed silo cover that effectively protects the water inside a silo from contamination, algae growth, and evaporation – all year round, in any climate. With this latest generation, Genap introduces a completely redesigned concept. The key difference compared to other systems on the market lies in its construction: the GenaDome PRO is entirely free-standing and selfsupporting. The frame stands on its own support points around the silo and does not rest on the silo rim. The wind and snow loads no longer put additional weight on the silo rim but are supported by the self-supporting design. The new structure now complies with a snow load of 56 kg/m² (applicable to roofs with a slope of up to 30°). The structure has been statically calculated and engineered for long-term use in all weather conditions. The galvanized steel frame is covered with a reinforced Genatex 450 membrane that resists UV radiation and temperature fluctuations. An integrated manhole ensures continued access to the silo. And if the silo lining needs to be replaced? It can be done without removing the dome.

Genap’s GenaFlexstore® represents a revolutionary advancement in water storage technology, combining liner and cover in a patented, seamless solution. This cutting-edge system virtually negates any external impact on water quality, ensuring the integrity of the stored water is maintained at its highest level. With its integrated design, the system dramatically reduces water loss through evaporation, optimising the use of the silo’s full capacity. Unlike traditional systems, issues such as algae growth, wave action, evaporation, and wind-borne debris are things of the past with the GenaFlexstore®. It excels in its suitability for use in areas prone to rain and storms. The meticulously designed drainage system ensures that rainwater and debris accumulating on the cover are neatly channeled away through a wall drain. Moreover, the design of the GenaFlexstore® ensures that the cover does not extend beyond the edge of the silo. This significantly reduces the system’s susceptibility to wind in contrast to other cover systems which can be adversely affected by strong wind conditions. The GenaFlexstore® is crafted from a flexible and highly UV-resistant reinforced PVC membrane for both the walls and cover. The base lining is made from a geomembrane that is tailored to the application. The GenaFlexstore® is versatile, suitable for storing all types of liquids, including chlorinated water, potable water and liquid fertiliser.

The Genafloat® from Genap is an innovative, floating cover for water reservoirs. Our Genafloat® is specifically designed to combine durability with effective protection against algae growth, evaporation, and wave action. This water covering system maximises the storage capacity of the water reservoir while maintaining water quality. The semi-enclosed Genafloat® is made from a double-sided coated, open-weave fabric and conforms to the shape of the bottom of the reservoir. The Genafloat® is available in both open and semi-closed versions. For new construction projects, the semi-closed system is often preferred; this system offers extra protection against leaf debris by attaching to the slope.

Potentially one of the highest yielding varieties with a combined intermediate resistance for Cucumber Green Mottle Mosaic Virus (CGMMV) and Powdery mildew (Px).

High yield potential combined with Intermediate Resistance to Powdery mildew and Cucumber green mottle mosaic. DRCE1355 delivered up to an average of 10% higher yield potential with comparable fruit weight as reference CUC138 as observed in 2022 and 2023. The CGMMV resistance of DRCE1355 has proven to be one of the best resistance levels available on market.

Even the best greenhouses require regular maintenance for a long life. We maintain your greenhous periodically and replace or repair your parts in a timely manner to prevent defects. This way your greenhouse is always in an optimal condition and you avoid unnecessary repair costs.

GreenSwitch® is the world-first patented process based on Pure Green Agriculture technology turning manure into organically derived Nitrate fertilizers for the high-tech greenhouse sector and open-field fertigation. GreenSwitch® encourages smart-farming practices, opening a new horizon for more sustainable agriculture and precision crop nutrition.

GreenSwitch® Potassium Sulfate is a pure and fully water soluble fertilizer with a close to zero carbon footprint suitable for foliar and fertigation application.

With a Gripper you can quickly bend the branch into a nice shape. Grippers offer a perfect alternative for other pot plants, as they clamp around the branch and plant support. Your creativity is given room with these Grippers: they can be square, round, pyramid shape or heart shape – it can all be done. The Grippers are available in various colours and sizes and give each plant the look it needs.
