The Polish Krasoń Group produces around 414 million vegetable plants per year. These are mainly supplied to domestic vegetable growers.
The family is strongly committed to further expanding their operations, and sustainability and energy conservation are also key priorities. For this reason, they have invested in dehumidifiers. Thanks to these units, the leaves dry faster, and disease pressure is reduced.

To save energy, three years ago the company also purchased DryGair units from Royal Brinkman. They now have nine of these dehumidifiers at their Złotów site. “We noticed that the humidity in the greenhouses was often too high,” Krasoń says. “So we had to open the vents. But that also meant that we lost a lot of energy, not least because we have extremely cold winters in Poland. Using dehumidifiers has enabled us to keep the vents closed and save substantial amounts of energy.”
According to the plant grower, the units also have a positive effect on the greenhouse climate and plant quality. “In the spring, we often water the cool-season vegetable plants with overhead sprinklers. Thanks to the DryGairs, the leaves dry faster – especially on cloudy days – and the disease pressure is reduced. We also have less of a problem with mildew. And that in turn means we need to use less crop protection products.”
According to the grower, the units also have clear added value in the production of tomato plants. “They just grow better: after all, tomato plants don’t like very high humidity. We also have less of a problem with oedema now, which some tomato varieties are quite susceptible to.” Because the results have been so positive, additional units are now high on the company’s wish list.
Krasoń is using nine DryGair dehumidifiers at their Złotów site. There are also several tomato growers in Poland who have good experiences with these dehumidifiers. According to these growers, they now have a more similar climate, save energy, and have fewer problems with botrytis.
