Daardoor ontstaan op enkele plekken warmtestuwing en neemt het risico op broei toe. De beluchtingsspeer van Jansen&amp;Heuning is speciaal ontwikkeld om dit snel en doelgericht aan te pakken.<\/p>\n<p data-start=\"955\" data-end=\"1246\">Onze speer is eenvoudig in te zetten als aanvulling op bestaand ventilatiesysteem, maar is ook uitstekend inzetbaar als zelfstandig middel om graan te koelen en te drogen. De speer combineert praktische bruikbaarheid met technische kracht, ideaal voor gebruik in zowel silo\u2019s als vlakopslag.<\/p>\n<h2 data-start=\"955\" data-end=\"1246\">Hoe werkt de beluchtingsspeer<\/h2>\n<p>In de onderstaande video wordt een visueel beeld gegeven van de beluchtingsspeer in werking.<\/p>\n<p data-start=\"955\" data-end=\"1246\"><iframe src=\"https:\/\/www.youtube.com\/embed\/nU_hmZMuQNk\" width=\"560\" height=\"315\" frameborder=\"0\" data-mce-fragment=\"1\"><\/iframe><\/p>\n<h3 data-start=\"1248\" data-end=\"1578\"><strong data-start=\"1248\" data-end=\"1287\">Testresultaten uit Deens onderzoek<\/strong><\/h3>\n<ul>\n<li>Koelt circa 100\u202fton graan per positie<\/li>\n<li>Op 3\u202fm afstand nog 30\u202fm\u00b3\/luchtdoorvoer per uur per m\u00b2 oppervlak<\/li>\n<li>In een silo van 7,5\u202fm daalde de temperatuur binnen 22\u202fuur van 18\u202f\u00b0C naar 17\u202f\u00b0C in de bovenlaag en van 28\u202f\u00b0C naar 20\u202f\u00b0C onderin \u2013 wat aantoont dat koude lucht de warmte opdrijft<\/li>\n<\/ul>\n<h2 data-start=\"1900\" data-end=\"1935\">Waarom deze beluchtingsspeer?<\/h2>\n<ul>\n<li data-start=\"1939\" data-end=\"2033\">Gericht gebruiken in kritische zones waar vocht en temperatuur boven de veilige norm stijgen<\/li>\n<li data-start=\"2036\" data-end=\"2114\">Verhoogt de effectiviteit bij bewaring van graan, voorkomt kwaliteitsverlies<\/li>\n<li data-start=\"2117\" data-end=\"2210\">Te gebruiken naast of zonder bestaande beluchtingsinstallatie \u2014 volledig modulair inzetbaar<\/li>\n<li data-start=\"2213\" data-end=\"2291\">Technisch op niveau dankzij gecontroleerde luchtstroom en solide performance<\/li>\n<\/ul>\n<h3 data-start=\"1580\" data-end=\"1893\"><strong data-start=\"1580\" data-end=\"1598\">Specificaties beluchtingsspeer\u00a0<\/strong><\/h3>\n<ul>\n<li>Ventilator 1,1\u202fkW, 2.800\u202fRPM \u2013 luchtcapaciteit 1.500\u20131.700\u202fm\u00b3\/uur<\/li>\n<li>Perforatie 1,5\u202fmm<\/li>\n<li>Compleet geleverd met boorhulpmiddelen \u2013 optioneel met kabel en stekker<\/li>\n<li>Gewicht 23,9\u202fkg<\/li>\n<li>Standaard lengte 2\u202fm<\/li>\n<li>Grafiek toont luchtsnelheid in het graan op verschillende afstanden tot de speer.<\/li>\n<\/ul>\n<p><iframe src=\"https:\/\/www.youtube.com\/embed\/_8dAjRwwWz8\" width=\"560\" height=\"315\" frameborder=\"0\"><\/iframe><\/p>\n<h3 data-start=\"1871\" data-end=\"1968\"><strong data-start=\"1871\" data-end=\"1882\">Contact <\/strong><\/h3>\n<p data-start=\"1871\" data-end=\"1968\"><span style=\"font-size: 16px;\">Heeft u vragen over graanbeluchting in uw opslag?
