At Van Dijk heating we specialise in air movement and distribution. As part of our unique climate-controlled greenhouse system we supply various components that can also be used in semi-closed greenhouse systems. These fans, ducts and other components can be used in a range of horticultural air and ventilation systems. The climate-controlled greenhouse system gives the grower greater control over the climate in the greenhouse and provides more options for control. Controlling the climate and humidity levels more precisely means that the crop stays in better condition and reduces the risk of disease.
