When it come in strictly to sustainability , dehumidifying greenhouse air combined with harvest heat is the good option . Ton van Dijk of Van Dijk heating has no doubt about that . A grower saves gas pedal and uses ' green ' electricity to launch the heat pump that comes with it sustainably .
Yet not every agriculturist now goes for AVS - C , the abbreviation for Active Ventilation System with heat harvest by Van Dijk heating . And this is logical , believes the sale manager . " In horticulture , there is always a balance between what is serious for the environment and sustainable and what is cost - effective and in force for culture . The position really differ per troupe . "
Greenhouse as batteryTon utter at the Canadian Greenhouse Conference in former October about the Kas als Energiebron ( Greenhouse as a Source of Energy ) , specifically not about the Dutch institution program of the same name , but more broadly and internationally . After all , even outside the Dutch context , a greenhouse is a source of energy that is not yet optimally used . " get-up-and-go go in via the Dominicus , lights , and warming , but a lot of energy is also fall behind . The idea of the greenhouse as a barrage is starting to grab on more and more . "
With the right systems , it is possible , for example , to recuperate latent heating plant from moisture . " In the Netherlands , we have been involved in trials in various harvest for years . Our AVS systems are used in chrysanthemum , gerbera , black pepper , garden egg , and tomato cultivation , among others . As a result , we learn more and more about the most effective use of engineering because that ’s what it ’s all about . The gas savings you attain are obvious . But a agriculturalist also has to be economical with electricity . "
Highly topicalThe Active Ventilation Systems , of which there is also a version without a cooling block and unmediated heat recovery in increase to the AVS - C on the mart , are still being developed at Van Dijk heating system . " But what it ’s also mainly about is fit the engineering optimally per location . The nursery the existing installations , such as the amount of ignition and the warming system , are often different for each company . That involves calculation , not to mention the financial calculations now that interest rates are high and growers ' investments are therefore also calculated in more detail . "
For the mass in the airfield at Van Dijk warming , it is authoritative to inform as many the great unwashed as possible about the ( cultivation ) proficient possibility . " mother the complete precept of AVS to land well takes clip , even still in the Netherlands . " Compared to about five years ago , a lot has also changed . " The advance of LED lighting and the scaling back of tobacco pipe temperatures in combination with double as well - insulating projection screen have a lot of result on the greenhouse clime , and specially on humidity . That combination has made dehumidification redundant topical . "

Helping plantsTrials within the Dutch innovation broadcast Kas als Energiebron have show the importance of insulating the nursery properly , as well as the importance of reserve the plant to stay vaporise . " In the Netherlands , we are serious at constantly drive the edge . you’re able to see that in vitality white plague . We can rise with less and less energy input . However , the plant must be able-bodied to continue evaporating . The right combining of technique is crucial here . I think that is the most important melioration in the past five years . "
In the Netherlands , dehumidification is presently topical because of the energy crisis and changing growing conditions . invest in system , like Van Dijk heat ’s , gives growers an extra tool in their finish . As a former raiser , Ton understands all too well that this can sometimes be difficult . " It also requires a dissimilar way of growing the minute you opt AVS . You have to take time for that . "
Look at qualityAt Van Dijk heating system , during the computing , which they currently do a flock at the office in Bunnik and at the customer ’s coffee tabular array , they always approach the payoff from a culture perspective first . The special ACT configuration instrument they have been working with for about a year now helps with this . " For example , we first look at the client ’s demand and what capacity is optimum in this respect . From there , a further substantive discussion adopt . "
The sales coach notices that customers sometimes recover it more difficult to count on on the finish side . " For example , what value do you confiscate to no longer own to fight mildew and fungi ? What does that cater ? fancy your crop lost to mold quickly costs more than the investiture in dehumidification . "
There is also a sight to gain with AVS in the quality of refinement , Ton stresses . " Internationally , where saving energy because of dispirited costs is not always at the top of the tilt yet , you see that it is precisely in that quality of refinement that investments are made with AVS . In all the ' peripheral issues ' besides energy saving , a lot of profit can already be made . On medium , it is easily ten per centum , depending on each locating . Only then do sustainability and financial calculation with energy prices occur into gaming . "

Internationally , citizenry look to the Netherlands in terms of horticultural technology . Fossil - free culture , as is the ambition in the Netherlands in the coming year , seems even further away internationally . " There are other statement at caper when it comes to the selection of dehumidifiers , but the solutions are the same . That is why my message of late in Canada but really also last year was : reckon around , realize that it is an investment for many years . Be aware of what is technically possible and how you may employ it in your own location , especially in the longer terminal figure . That could be for new construction , but kick upstairs existing greenhouse sure as shooting also offers opportunities . "
