Coating sprayers

Efficient solutions for applying greenhouse roof coatings

Applying a coating to the greenhouse roof helps regulate light intensity inside the greenhouse. Light is essential for crop growth, but too much light can be harmful. Whitewashing or coating the greenhouse roof allows for better control of light levels and creates a more stable greenhouse environment.

For optimal results, it is important to apply the coating evenly across the greenhouse roof. This ensures uniform light distribution inside the greenhouse and prevents variations in light intensity.

Flexible Use of Machines
Van der Waay’s coating sprayers are designed to apply coatings quickly, accurately, and evenly. Various machines, such as roof washers and even a Glass Repair Cart, can be equipped with spray booms. This allows these machines to also be used as coating sprayers for the efficient treatment of large greenhouse surfaces. This means that a single machine can be used for multiple tasks, which increases flexibility and efficiency in greenhouse roof maintenance.

Efficient and reliable

Coating sprayers offer, among other things:

even application of greenhouse coatings;
high capacity for large greenhouse surfaces;
efficient use of coatings;
safe working at heights;
reduced physical strain on staff.

The Top Sprayer is compatible with coatings from well-known brands such as Redusystems, Hermadix, Sudiac, and White Circle, and can be combined with Van der Waay pump units for mixing and pumping coatings and coating removers.

Pomp units

Providing the greenhouse deck with an even coating is precision work. It is therefore of great importance that the spray liquid is prepared correctly and that the pump is suitable for pumping these coatings.
The Van der Waay pump sets are fully adapted to the chalk machines used to apply the coating.
