I'm inclining towards an active vaporizer and have not begun to consider a passive vaporizer. Nor will I ever.
I'm aiming at bettering treatment times and being capable of treating hundreds of hives a day. By sublimating oxalic acid, treatment needs to be quick and effective.
Their already exists such a vaporizer, but units costs thousands. Nary will many accept the idea nor find it worthwhile. Maybe I'm off base here, but personally I would not consider spending thousands for such a unit.
Neither will I waste my money substituting for a piece of equipment that I will outgrow too quickly. There exists a gap in between that allows one to treat with oxalic acid quickly, efficiently, cheaply and more compact than the vm vaporizer.
I'm not satisfied with either alternative and so here I am setting out on a journey to fill that gap that I believe many are willing to consider.
This shouldn't be difficult to remedy as a unit already exists in Europe. Problem is they charge over 500 dollars for their unit.
I believe a unit could be made for less than 200 dollars. I have yet to see any units available in the US of this nature. We need to develop one and offer this idea to others to better facilitate oa treatments.
With this unit, all that's needed is one of three different power sources to run the unit. Outlet power from a grid source, battery power with an inverter, or use of a small generator. All on par with the same needs of a passive vaporizer.
Alright, so basing our idea from the European model:
We have most ofthe cat in the bag so to speak.
We start with the Heat gun to sublime the oa:
Next the biggest challenge, identifying the housing used for the oa. I've done some searching, and with some previous conversation, it looks like it could be a water meter housing.
After, it's simple. A pipe attached and then through a piece of wood to block the entrance.
Anyone care to join me in finding a housing that would be appropriate for this purpose?
YouTube videos are available of this unit in action.
