The family have business P.H. Kuivenhoven Greenhouses inc . strive to maintain their place as the leading Gerbera grower in the business . Recently the variety of ownership to Gilbert and Wilma Kuivenhoven was complete and they now run all of the 230,000 square ft of the facility in Oxford County , Ontario . These Canadian agriculturalist set the bar luxuriously for product timber and they conjure the bar even higher with dehumidification from Nivolutions .

optimise craw increase with dehumidificationGilbert Kuivenhoven is ceaselessly looking at improving the greenhouse climate and confide in 2017 to dehumidification for the next improvement in his Gerberas production . By apply the Growing by Plant Empowerment rule and finetuning the melody circulation with dehumidification , Gilbert says : “ We wanted to optimize crop increment by being able to blackout during long outdoor day lengths , controlling the sidereal day - night cycle . ” However , using the amnesia concealment to do so leads to a make - up of warm humid air in the greenhouse . Pulling a crack in the screen is not his desired solution as this negatively move the day - nighttime cycle and leads to cold drafts that impact the clime .
To maintain the required humidity and temperature levels Gilbert need a method to dehumidify and cool the nursery , whilst being able-bodied to maintain all other climate parameter . “ This mode we can control daylength , humidness and temperature , ” he explains .
Gilbert meet Herman Dunnink , his advisor and salesman from the Canadian company Global Horticultural Inc. for advice . Together they discussed various options and look more closely into combined dehumidification and air travel circulation means . As Herman says : “ Gilbert was already making use of vertical air travel circulation fans from Nivola , the Nivolators , and back then in 2017 Nivola late released a combined dehumidification system . Gilbert was positive about the results the Nivolators delivered , so a organization that combined those devotee with dehumidification caught our pursuit . ”
This newfangled intersection , the Nivolution , works with the Nivolators and looked to gibe the bill . Marion Lestraden , managing music director from the Dutch firm Nivola , elaborates on the combined functionality of the system : “ The Nivolution pulls atmosphere from above the screen and blows it underneath the cover via a duct , like how a crevice in the screen allows for air exchange . Only now you control the amount of air exchange and all line that is mishandle in the glasshouse is evenly distributed by the vertical breeze circulation from the Nivolators . You are in control of the melodic phrase rally at all times and there is no risk of cold selective service . ”
Installation in the greenhouse“The Nivolution consist of a channel that passes in between the screen and the corbel . Gilbert and I believed it would be a design and installment challenge to not have the organization interpose with the filmdom . We contacted Nivola and Kuivenhovens CRT screen facility company about this and they direct the challenge in their collaboration , ” explain Herman from Global . “ Nivola provides a choice between a single epithelial duct that clamp to the truss on one side and a treble canal that encloses the corbel on both sides . The installation companionship advised us to use the single duct for Gilberts specific requirements . ”
After the installation of the Nivolution was read tutelage of , it was time to start using the system . The frame-up in programming provided a dissimilar form of challenge explains Gilbert : “ The relation between humidness and temperature , both inside and outside the glasshouse , is the key for getting the maximal return on this investiture . As a grower understanding the physical construct behind it can be difficult at times , as you need to allow go of some of your previous anchor points in favor of unlike ones . ”
Fortunately , the setup run swiftly as Gilbert has put the effort into larn and mastering the forcible concept . In improver , he uses climate computers from Hoogendoorn Growth Management , who have a lot of experience with this state - of - the - fine art approach .
Cooling with outdoor strain below the exterior temperatureAfter more than four years of using the Nivolution dehumidification system Gilbert is very positive about his control of the climate and the daylight - night cycle . “ We see right mood humidness and climate temperature control as we can also practice the crop now for cooling determination . With the Nivolution we can attain chilling of 4 ° C over outside temperatures using the principle of spring up by Plant Empowerment . This for us translates into production since with cool temperatures new buds are form . Another welfare from the cooling is that our quality is increase . ”
Asides from the increment in quality and production the benefits do not stop yet . “ Due to proper clime control condition we also have adept disease control , ” explains Gilbert . The habit of screens is often also associated with economise energy . Department of Energy economy were considered in the investment in the organisation , but for Gilbert the harvest come first .
As Marion observe upon reflect the undertaking : “ Even with the quislingism with Gilbert , Herman and the instalment company we could have made some tweak to make the instalment of the system easier back in 2017 . Gilbert is the first exploiter of the Nivolution outside The Netherlands and we bring out some elbow room for improvement on our end . The Nivolution is usage made for the customer and those tweaks for both assembly and shipping were directly incorporated for future projects . ”
She continues : “ As greenhouses become more and more forward-looking it becomes increasingly crucial to communicate properly with the client . By turn close together with P.H. Kuivenhoven Greenhouses Inc. and Global Horticulture Inc. we are now even more suited to append the Nivolution according to a customers ’ existing nursery needs . ”

A smile on your faceGilbert Kuivenhoven reaps the fruit of his efforts he tell : “ What especially emerges is that the wet and the temperature at night can now be regulated in a much better manner . Apart from that , we can aim the vigor pulmonary tuberculosis better since the dehumidification capacity of the Nivolution can be calculated . Before , a crack was pulled into the silver screen with the guess of the gist . ”
Every prison term Gilbert walks into the greenhouse and see the gerberas growing , he stimulate a smile on his face . Both the timber and amount of the Gerberas is increase by the additional control he has over his climate and daylight - dark cycle . And at the same clip , his energy use of goods and services is reduced . As for the time to come he is optimistic that P.H. Kuivenhoven Inc. will obligate its leading view for years to get along and that they will raising the Browning automatic rifle even further .
