For the last two years the fight against varroa has been made with the use of oxalic acid and in particular with its sublimation. A battle with very good results as the sublimation is best accomplished with a modern Sublimox machine.
In this post I will mention some interventions - improvements made to the machine after two years of use. First I placed under the boiler a hook that secures the machine to the blister after I chose to channel oxalic acid from the side of my working base.
Secondly, the boiler is coated with a titanium thermal insulator for less heat loss to the environment and better sublimation at very low ambient temperatures.
Thirdly the removal of the part given by the manufacturer to supply the device with oxalic acid, and the construction of an aluminum cuff with two o-ring temperature-ready to receive a 3/4 valve.
This reduces the machine's oxalate feed time greatly. And fourthly, the boiler base is strengthened so that it can withstand the operating pressure of the valve.
