Pligt Professional is a producer of flowering potted plant . With a aerofoil area of 13 hectare , spread across three locations , and a wide range of plant species , the family clientele supplies three to four hundred thousand plants every week . An important element for the organization is the delivery of a lineament ware . To realize this , various high - quality refinement techniques are give in the greenhouses . Vostermans spoke with oversee manager Gert van der Pligt about the decision to install Multifan Horizontal Circulation Fans in the recently built glasshouse that accommodates five hectares of potted roses .
Lighting and excess heatPreviously , Pligt used SON - T firing in all greenhouses . This regularly result in a substantial heat surplus . To further improve quality , the company latterly switched from SON - T to lead lighting . This further increased the scant tier without further increasing the heat generated by the SON - T lamps . Gert explicate : “ The right-hand level of light and light spectrum is very authoritative for growing potted roses . lead lighting offers many raw possibilities in this area , applying the right spectrum for each finish phase and also save substantially on energy .
Circulation for a uniform temperature distributionThe changes to the lighting organization in the greenhouse later on also make for changes to the ventilation and strain circulation . “ To withdraw the excess heat , we used an Airmix breathing system in combination with circulation fans in the glasshouse with SON - thyroxin lighting . ” With the installment of the LED lamp , the excess oestrus disappeared , and the priority of the ventilation system for Pligt Professionals now lie down in good circulation for uniform temperature distribution . In addition , horizontal circulation fans exert an active mood for the crops . For that understanding , Multifan Greenhouse Fans are now used in the young greenhouse . “ By using Harmony screen , moisture restraint will become more of a challenge . More moisture is keep on under the closed screens , and the importance of good air dispersion and breeze circulation is greatly increased . We have yet to find out whether sufficient moisture can be removed with the ventilation organization . So far , thing are going well by applying a minimal gap in the screen and a higher tube temperature with just fans . ”
Energy costsA nice welfare for Gert is the down vigour consumption of the newfangled devotee . “ Although we ’re now seeing staggeringly rising gas prices , electricity price will also be significantly higher in time . The king consumption of rooter is only a pocket-sized part of our total energy consumption , but it is still important to invest in energy - efficient solutions . Compared to the system with Airmix , the superpower consumption has more than halve . So we still hold open a lot of vigor there . ”
