{"product_id":"dramm-ulva-rotary-atomizer-sprayer","title":"Dramm - ULVA+ Rotary Atomizer Sprayer","description":"\u003ch2\u003eULVA+ Rotary Atomizer Sprayer\u003c\/h2\u003e\u003cp\u003eThe ULVA+ is a battery powered rotary disk atomizer for low volume and ultra low volume application of insecticides and fungicides. A spinning disk shears the liquid into 50 to 60 micron droplets at an output of 25 to 60 ml per minute, so droplet size is set mechanically rather than by pressure through a nozzle. Those droplets are light enough to drift on the air movement already in the crop and settle on all plant surfaces as they fall, which is why the machine belongs outdoors or in a house with real air movement rather than in a sealed still space. One 1 liter bottle treats up to 6,000 sq ft.\u003c\/p\u003e\u003cp\u003eThis page lists the machine complete, supplied with its batteries and charger, so there is nothing else to buy before the first pass. Dramm rates a charge at about 40 hours of spraying, which covers a long run of weekly rounds before the charger comes out again. Choose the ULVA+ by site rather than by crop: it relies on natural air movement to carry and place the droplets, so outdoor row crops, cut flower blocks and vented houses suit it, while a sealed, still greenhouse is fogger work instead. Because the disk fixes the droplet spectrum, the variables you actually control in the field are the flow rate setting, walking speed and pass spacing, not a pressure knob, and the low output means a 1 liter fill covers ground that would take many gallons through a hydraulic sprayer.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eConfiguration\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eComplete machine, supplied with batteries and charger\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eType\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eBattery powered rotary disk atomizer\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDroplet size\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e50 to 60 microns\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOutput rate\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e25 to 60 ml per minute, variable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBottle capacity\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1 liter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCoverage\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eUp to 6,000 sq ft per 1 liter fill\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePower\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eD cell batteries; batteries and charger supplied\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRun time\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eAbout 40 hours of spraying per charge\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eShipping weight\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e5 lb\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eA spinning disk rather than a nozzle sets droplet size mechanically, so it does not shift when supply pressure does.\u003c\/li\u003e\n\u003cli\u003e50 to 60 micron droplets stay airborne long enough to move through a canopy and settle on all plant surfaces.\u003c\/li\u003e\n\u003cli\u003eOutput of 25 to 60 ml per minute means one 1 liter fill treats up to 6,000 sq ft.\u003c\/li\u003e\n\u003cli\u003eVariable flow rate, so output can be matched to walking speed and row width.\u003c\/li\u003e\n\u003cli\u003eRuns on D cell batteries for about 40 hours of spraying per charge, with batteries and charger in the box.\u003c\/li\u003e\n\u003cli\u003eNo pump, hose or compressor and a 5 lb shipping weight, so one operator carries the whole outfit.\u003c\/li\u003e\n\u003cli\u003eHandles the low volume and ultra low volume rates that cut the water hauled onto a block.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eIdeal Applications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eInsecticide and fungicide rounds on outdoor row crops\u003c\/li\u003e\n\u003cli\u003eCut flower blocks and field beds\u003c\/li\u003e\n\u003cli\u003eVented greenhouses and hoop houses with natural air movement\u003c\/li\u003e\n\u003cli\u003eSpot and perimeter treatment where setting up a cart sprayer is not worth it\u003c\/li\u003e\n\u003cli\u003eLow and ultra low volume programs where water volume on site is the constraint\u003c\/li\u003e\n\u003cli\u003eFollow-up passes between full hydraulic sprays\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cem\u003eGrowers who also need to treat sealed houses pair the ULVA+ with a Dramm Autofog or Coldfogger, and keep an MSO hydraulic sprayer for the drench, wetting agent and sanitizer work that needs volume rather than droplet drift.\u003c\/em\u003e\u003c\/p\u003e","brand":"Dramm","offers":[{"title":"Complete with batteries and charger","offer_id":52800842694967,"sku":"ULVA+","price":501.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/0341\/5863\/files\/dramm-brand-placeholder_2558ea8f-7341-40b5-9b8f-b8390b127a7e.png?v=1786400658","url":"https:\/\/www.blacklabelsupply.io\/products\/dramm-ulva-rotary-atomizer-sprayer","provider":"BLACK LABEL","version":"1.0","type":"link"}
