Baffled Swap Body Tank Container
In events where the minimum loading degree of 80% cannot be met, due to weight regulations for classified products, there is an option to fit baffles in tanks containers. This is often seen in swaps with a capacity of 30.000 liters (fitted with 3 baffles) and 35.000 liters (fitted with 4 baffles). This has an impact on weight and costs. Besides the baffles there is an extra need for cleaning hatches and spill boxes on top of the tank to be able to clean the unit after discharge.
For more info on baffled tanks please contact our friendly staff or check the regulations (IMDG or ADR) section 4.3.2.2 / 4.3.2.4.: “ where shells are not divided by partitions or surge plates into sections of not more than 7.500 liters capacity, they shall be filled to not less than 80% or not more than 20% of their capacity” .
These tank containers are not used in world-wide transport and therefor often used in ADR environment/ European traffic leading higher safety standards like:
One or two handrails, often bottom operated, ground operated vapor return (GOVR), Baffles fitted, hazardous plackard boards, spillbox covers, bottom cabinet with a door etc. etc.
The standard tank containers are built to international standards: ISO,CSC, TIR, UIC, UN PORTABLE TANK (US-DOT, IMDG and ADR 6.7). Often these tank containers are built as dual certified to include ADR TANK 6.8, like L4BN.

Details of baffled Swap Body Tank Containers
a 20”/DN500 manlid is fitted with 8 swing bolds. The manlid is fitted with a standard PTFE braided manlid gasket. Optional this van be changed to other gasket material.
To be able to have a good cleaning performance at automated cleaning facilities 3 or 4 extra cleaning openings are added: 12”/DN300 manlid, fitted with 4 swing bolds. The cleaning hatch is fitted with a standard PTFE braided manlid gasket. Optional this van be changed to other gasket material.
The internal of the vessel is fitted with vertical corrugated stainless steel baffles (316L). These baffles cover 70% of the internal diameter and due to the vertical shape it is easy to access and walk in the tank.
The Unportable Tank T11 is fitted with a 3 closure bottom discharge supplied by a worldwide leading manufacturer. The discharge valve includes: a highlift 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 third closure.
Regularly we modify the connections on customer request to a cleanflow version or changing 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) for a clean operation and easier fitment of TIR seals.
A standard tank is fitted with a DN80/3” connection on top. On request a connection can be added for easy filling and or discharge form the top and a bottom operated top discharge is one of the possibilities where our team can assist.
A full bottom operated airline is fitted, a so called ground operated vapor return (GOVR) including: bottom operated airline valve, piping to the bottom/rear of the tank and manometer including a 2nd valve (dimension and connection to be discussed).
A T11 tank container is fitted with a safety valve that opens at 4.4 bar (10% above the test pressure). Besides the pressure only version is a pressure + vacuum version optional. Each tank container is prepared for future fitment of a bursting disc. (needed for both T12 and T14 specification)
The frame is made of mild steel and meet the ISO dimensions of a 20ft. box container. The barrel is connected with the frame and is a part of the integral construction, therefore are top rails not needed but can be added on request.
The front and the rear of the tank vessel are protected by additional frame members (bull bars).
Each tank container is fitted with a stick on analogue thermometer, reading from -20 to max 160 degrees
°C. On request a digital version can be added as well as thermometers with a probe to have a better reading of the product temperature.
Each tank container is fitted with an anti-slip ladder at 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 a clean operation and easier fitment of TIR seals.
On request one or 2 collapsible handrails can be fitted, top as well as bottom operated.
Each tank container is fitted with minimum 8 steam runs to be able to heat up the product with warm water or steam. The covered area is 8 SQM. On 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, the majority has 50mm insulation and cladding. The insulation material varies from PU, Rockwool, glass wool or a combination. The cladding material is either aluminum, GRP or Stainless steel.
