Pligt Professionals is a producer of flower potted plants . With a surface area of 13 hectare , spread across three location , and a wide range of plant species , the family business supplies three to four hundred thousand plants every week . An important element for the organization is the obstetrical delivery of a quality product . To make this , various eminent - quality finish technique are applied in the greenhouses . Vostermans spoke with manage director Gert van der Pligt about the decision to install Multifan Horizontal Circulation Fans in the recently make greenhouse that accommodate five hectares of potted roses .

Lighting and surplusage heatPreviously , Pligt used SON - thyroxin light in all glasshouse . This on a regular basis result in a substantial heat excess . To further better character , the companionship lately switched from SON - metric ton to LED inflammation . This further increased the light level without further increasing the passion beget by the SON - T lamps . Gert explains : “ The right storey of light and light spectrum is very of import for grow potted roses . lead lighting volunteer many Modern opening in this sphere , applying the right spectrum for each cultivation phase and also save well on energy .
Circulation for a unvarying temperature distributionThe changes to the lighting organization in the greenhouse subsequently also brought changes to the ventilation and air circulation . “ To hit the supernumerary warmth , we used an Airmix ventilation system in combination with circulation fan in the greenhouses with SON - T lighting . ” With the installation of the light-emitting diode lamp , the excess heating go away , and the precedency of the ventilation organization for Pligt Professionals now lies in good circulation for unvarying temperature distribution . In add-on , horizontal circulation fans maintain an active climate for the crops . For that reason , Multifan Greenhouse Fans are now used in the new greenhouse . “ By using Harmony screens , moisture control will become more of a challenge . More wet is retained under the closed silver screen , and the importance of good air dispersion and air circulation is greatly increased . We have yet to find out whether sufficient moisture can be removed with the breathing system . So far , things are going well by apply a minimum gap in the screen and a higher tube temperature with just sports fan . ”
vigour costsA nice welfare for Gert is the lower zip white plague of the new fans . “ Although we ’re now seeing tremendously rise gas prices , electricity price will also be importantly higher in time . The power consumption of fans is only a modest part of our total energy consumption , but it is , of course , still significant to clothe in energy - efficient solutions . liken to the system with Airmix , the power consumption has more than halved . So we still economize a lot of energy there . ”
