Tanks
Assmann’s Full Drain Outlet (FDO) assembly drains tanks of 2,500 gallons and larger without mechanically installed nozzles, while Assmann’s double wall tanks, from 20 to 8,850 U.S. gallons, eliminate chemical spills without the expense of lined concrete containment. A heavier-top sidewall and dome prevent dome collapse, while a primary inner tank and a secondary locked-on outer tank protects against chemical spills.
