Maximize efficiency with baffles in tank containers
Baffle installation in tank containers
When the minimum loading capacity of 80% can’t be met, installing baffles can be an effective solution. This is typically done in tanks with capacities of 30,000 litres (requiring 3 baffles) and 35,000 litres (requiring 4 baffles). However, adding baffles increases not only the weight but also costs. Additionally, companies should include cleaning hatches and spill boxes to ensure proper maintenance and safety.
Regulatory compliance for baffled tank containers
IMDG and ADR guidelines state that tanks with capacities exceeding 7,500 litres must be filled to either at least 80% or less than 20% of their total volume. This regulation ensures safety by preventing accidents during transport.
Safety standards for baffled tank containers
To comply with ADR and European transport regulations, baffled tanks must include essential safety features, such as handrails, ground-operated vapour return systems, hazard placard boards, and bottom valves. Moreover, most tanks are designed to meet ISO and UN portable tank standards, and many are dual-certified for that extra level of safety assurance ‒ particularly useful when carrying hazardous materials.
Benefits of baffled tank containers
Baffles reduce liquid movement, improving stability and safety during transport. They minimize spill risks, ensure safe handling of hazardous materials, and guarantee compliance with international regulations.

Details of baffled swap body tank containers
A 20”/DN500 manlid is fitted with 8 swing bolts. The manlid is fitted with a standard braided PTFE gasket. This can be changed to other gasket material as an option.
We can modify the connections to a cleanflow version or change the BSP connection to a quick-release coupling at your request. Our team is here to help.
Most tank containers are built for future fitting of a bottom cabinet (floor and door) – for a clean operation and easier installation of TIR seals.
Each container is fitted with a full-deck aluminium walkway to access the manlid, cleaning hatches, safety relief valve, and airline. Spill box covers can be added on request for clean operation and easier installation of TIR seals.
Upon request, one or two collapsible handrails can be fitted, both top-operated and bottom-operated.
