Maximize Efficiency with Baffles in Tank Containers
Baffle Installation in Tank Containers
When the minimum loading capacity of 80% cannot be met, installing baffles becomes an effective solution. This is typically done in tanks with capacities of 30,000 liters (requiring 3 baffles) and 35,000 liters (requiring 4 baffles). However, adding baffles not only increases the weight but also raises costs. Additionally, to ensure proper maintenance and safety, companies should include cleaning hatches and spill boxes.
Regulatory Compliance for Baffled Tank Containers
The IMDG and ADR guidelines, specifically sections 4.3.2.2 and 4.3.2.4, state that tanks with capacities exceeding 7,500 liters must be filled to either at least 80% or less than 20% of their total volume. This regulation ensures safe transport and prevents accidents during shipping.
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 vapor return systems, hazard placard boards, and bottom valves. Moreover, most tanks are designed to meet ISO and UN Portable Tank standards, and many carry dual certification, which enhances safety, particularly for hazardous materials.
Advantages of Using 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
The Unportable Tank T11 is fitted with a 3 closure bottom discharge supplied by a worldwide leading manufacturer. The discharge valve includes a high-lift internal valve that can be closed remotely by a cable on the side of the tank container, a butterfly valve as 2nd closure and a 3” BSP spigot as the third closure.
Regularly we modify the connections at customer request to a Cleanflow version or change the BSP connection to a quick release coupling. Our team is here to assist.
Most tank containers are built for future fitment of a bottom cabinet (floor and door) to facilitate clean operation an easier installation of TIR seals.
The frame is made of mild steel and meet the ISO dimensions of a 20ft box container. The barrel is connected to the frame and is a part of the integral construction; therefore are top rails are not needed but can be added upon request.
The front and the rear of the tank vessel are protected by additional frame members as bull bars.
Each tank container is fitted with an anti-slip ladder on the rear side for easy access to the top of the container.
Each container is fitted with a full-deck aluminum walkway to access the manlid, cleaning hatches, safety relief valve , and airline. On request spillbox box covers can be added for clean operation and easier fitment of TIR seals.
Upon request, one or two collapsible handrails can be fitted, both top-operated and bottom-operated.
Each tank container is fitted witha minimum of 8 steam runs to heat the product with warn or steam. The covered area is 8 SQM. Upon request, the number of steam runs can be upgraded to 12 runs. In addition a water glycol/electrical heated system can be added.
A small part of the fleet is non-insulated, while the majority has 50mm insulation and cladding. The insulation materials vary and include PU(polyurethane), rock wool, glass wool,or a combination of these. The cladding materials are either aluminum, GRP (glass-reinforced plastic),or stainless steel.
