Moisture problem in the glasshouse have always existed , but certainly in wintertime it is a challenge for many growers to dehumidify their greenhouse air . antecedently the slogan was : the heating high , the screen ajar and the air windows open . But that is not very energy effective , and a good deal of valuable CO2 is lose . That is why Royal Brinkman has , for a number of years now , the DryGair air dehumidification units in their smorgasbord . today , many ornamental and veggie grower have large moisture collectors , which are now even localise in the middle of the cap space ( and if applicable because of the peak ) in between the crop . Eef : " When install a building block on the concrete path or on an ebb and flow floor , it just come down to using the forklift and it is done . to also identify the units in the crop , we have squall on Van der Goes Europa bv to apply their expertness in lay cogeneration unit , to put the DryGair units . "
At Royal Brinkman , Eef Zwinkels is dealing with the unit of Israeli origin . " The idea comes from Israel , where they have a lot of air - conditioning expertise . DryGair works like a cold beer nursing bottle that you take out of the fridge . Like the moisture from the zephyr condenses on the cold glass , so the moisture in the greenhouse condenses on inhuman dialog box in DryGair . damp air is sucked in at the side and at the top blown back into the greenhouse , dry and somewhat warm up . "
With the units growers can remove 4.5 liters of wet from the air with one kW hour at 18 degrees and an RH of 80 per centum . The water runs along the panels in the unit to a container where it is accumulate and discharged via a hose . Besides drier glasshouse air , the main advantage is energy saving , says Eef . " I have examples where in the DryGair section the tube temperature is at 0 degree while in the control department a subway system of 30 degree is needed . In addition , the moisture guzzlers have a incontrovertible core on the RH , AH , MD.“Predominantly cosmetic growers have the units set up , about 95 pct according to Eef ’s estimation . " In the gerberas alone , seventeen units are now being installed in the weeks after the IPM . " But units are also used in greenhouse veg refinement . " It is true that the more full the craw is , the greater the wet trouble . With many vegetable growers , the harvest is still small and new for a considerable part of the twelvemonth , so moisture in the nursery breeze is less of a problem . "
Growers will have to moot whether the investment outweighs the energy saving and the good greenhouse air quality for the crop . " Too much wet in the air promotes fungus kingdom , so if the nursery air is well under control , growers can write on crop protection agents . It is also potential to connect a liter comeback to the whole , as cultivator themselves like to see the effect . "
The rise of inflammation in greenhouse vegetable finish to grow yr - round mean that Eef also expect an increase in the number of unit in the cultivation of vegetables . On average , there are three units per hectare , but each crop is different . " At a young plant life grower in Poland , they grow vegetable plants with six unit on two hectares , but in basil polish , for example , it is five unit per hectare . "
The use of DryGair works on two fronts . first off , the nursery tune is dehumidified , without the need for cold extraneous aura . second , the glasshouse air is well mixed by the fan . This results in an even mood without cold corners . This participating climate run to resilient crops . Users regularly say : ' I am in control with DryGair' .
