Expert Insights

The Expansion Tank is the key component for increasing sump capacity in UltraTech's modular IBC spill containment system, adding 65 gallons of containment volume between any two connected pallets. This low-profile tank (61" x 31" x 12.5") sits at floor level between pallets and connects via bulkhead fittings that allow spilled liquid to flow freely between the pallet and tank sumps. The 2- and 3-tote kits include expansion tanks, but the 4- and 5-tote kits include fewer or none—this standalone tank fills that gap. When ordering, also purchase Bulkhead Fittings (A1117U) for each new tank connection, and have the Assembly Kit (A1118U) on hand for the hole saw and tightening tools.
