A lover may seem like a simple product , but behind a apparently uncomplicated exterior lies plenty of work and applied science . Peter van der Putten , an area gross revenue director at the Dutch Vostermans Ventilation , recognize all about it . " You have to adjust to all EU standards regarding the effective use of energy . So , we unendingly work to have all our sports fan meet these regulations . "
Anticipating the normPeter explains that there are two relevant EU standards for fan manufacturers , which in turn get progressively levy . " In terms of efficiency , the motor has to adapt to standard IE3 , and the fan in its entirety has to conform to ERP standards . "
At Vostermans , they started working on this about ten class ago . It take a while to adjust to the standard , which find with the input of manufacturers . Nevertheless , Vostermans Ventilation already fulfill standards that are yet to be implemented , as Peter elaborates . " We ’re already doing better than is currently required . "
Being in controlTo make the fans more efficient , there are fundamentally two control to alter : the motor and the fan itself . " When it comes to the motor , we ’re talking about a bigger package , mean more copper and small tolerances for an effective motor . In this process , you ’re face for the most favorable combination between rotor and stator . "
Once you have receive the most effective motor , you move on to the lover . " you could adjust the number of blade , the blades themselves , and reduce the tolerance of atmosphere inflow . " So , there are many combinations possible for both the fan and the motor . All of this makes one matter clear , making fans more efficient is not as simple as it may sound .
This way , Vosterdams has managed to reduce the energy use of their Multifan Horticulture Ventilator by fifty percent compare to five old age ago . " The efficiency intimately doubled , which is a great measure . "
Continuously in developmentMarket feedback is essential for Vostermans to realize young developments . Certainly , efficiency is a vital tending point in the market , but strait has n’t been for a retentive clock time . " That has changed , " says Peter . " client require a fan that is as quiet as potential , so it ’s our Book of Job to make a compounding between efficiency and sound . "
To achieve that , Vostermans has entree to their own R&D department , equipped with a personal confidential information burrow . " We make everything ourselves and are also able to test everything beforehand . A epitome that exploit fine in possibility will still be try out in the wind burrow . We ’ll adjust it if necessary since theory and practice are not always in sync . "
Remove the grille?To close off , Peter share an interesting e - mail he find from a raiser , which illustrates the contemporary importance of vigour . " The grower need : ' How much energy could I save if I removed the grille from the fans ? ' It appears that it can save up to 15 Watt per fan . This may not seem much , but if the rooter are on most of the year , it can save you up to 5 - 6 % per yr , depending on the craw and time of the year . If the fan are hanging high enough , 2,70 metre above working height , this is also still permit . "
