Watertechnical units

Flexible partner in technical solutions for horticulture


Avant Projects designs and builds all of its water technical units itself. These are assembled and built entirely to the customer’s requirements. Our units are equipped with control panels made by ourselves. Because we use a standardised basic design for our units, we can produce the entire unit in our own workshop in a relatively short time. This way, the water technical unit only needs to be connected on site.
