If you have
A large storage tank and no appetite for an entry
Tanks up to 120 ft in diameter, crude or refined product service, sludge or paraffin on the floor, and an inspection date you cannot move.

Purpose-built equipment
Three systems, one philosophy: keep people out of the tank and keep wash water on site. PMI built two of them, RoosterEX and MudHog, in-house because the right equipment was not on the market. Compare them below, or describe your tank and we will pick the right one for you.

If you have

If you have
Compartments, baffles, agitators and weighted fluid, on a rig schedule where setup speed matters more than anything.
In every case
Whichever cleaning platform runs, the EC-AOP unit can treat the wash water on site and put it back into the wash.
Send the tank or system details and PMI confirms fit before anything mobilizes.
