A CargoMaxx-equipped vessel is fitted with re-loader tanks, one set per system. These are installed abreast in a row in the centre of the bulk room between the cargo tanks. The re-loader tanks are designed for working pressures between 0.20 and 6.6 bar(a) and come with a classification society approval certificate.

When the loading procedure starts, the product is first sucked into either one of the two re-loader tanks. Once filled, the re-loader tank is pressurised by air from the convey air compressor. Upon reaching a pre-set pressure, the pipeline to the storage tank will be opened and the product blown into the cargo tank.

For the receipt of the air/material mix and de-dusting of the suction air, the re-loader tank has a special filter installed, sized for the maximum capacity of the unit and with a dust emission of less than 5 mg/nm³. The dust-laden air is drawn through the filter elements of the filtration system, capturing the dust on the outer surface of the elements. The air passes through the fabric and is released into the atmosphere via vacuum pumps.

The filters are maintained in optimum condition, as each element is regularly cleaned by reverse jets of compressed air. the condition of the filters is permanently monitored in two ways: measuring pressure differences over the filters as an indicator of contamination, and checking for leakages or damage by a dust detection system, fitted in the pipeline between filters and vacuum pumps. If any irregularities are detected, the central control system automatically takes remedial action.

For inspection of the filter system, a manhole is fitted to the side of the re-loader tank. Filter elements can be replaced through the side opening.

All re-loader tanks are equipped with pressure and level monitoring devices, manholes, etc.
