Enclosed Top Cone Bottom Tanks are designed for stationary applications and are selected when a more complete drain-out of stored liquid is required; other applications include: water treatment, wine making, beer brewing, biodiesel / bio-fuels (WVO), liquid fertilizer, liquid feed, batch / mixing tanks, Slurry / Sludge (Settling Tanks), DEF Tanks (Diesel Exhaust Fluid), agricultural grains, and agricultural / industrial compatible chemicals. Cone Bottom or Conical Bottom Tanks come in various degrees of slope depending on the capacity and drain out speed intention. Tie-down slots or lifting lugs are available on some larger tanks. Tanks are manufactured from high-density polyethylene with U.V. inhibitors. Tank walls are translucent for level viewing and equipped with gallon and/or liter indicators. Cone Bottom style requires the use of a stand for support. Steel stands and additional fittings are sold separately.
