Problems with negative pressure while bunkering?
Especially bigger vessels are facing the problem of negative pressure at the bunker manifold. Traditional Drip Samplers cannot be used here. They need a positive pressure to allow the sample to flow into the sample container by gravity. The solution is the Automatic Fuel Sampler which does work with vacuum up to -0.8 bar.
The Automatic Sampler is connected to the main bunker line by a flexible hose for the mobile solution or by pipe fittings for the permanent installed version. After start it will automatically sample into the cubitainer and stop automatically after the pre-set bunker time. The sampler can sample into all size bottles or cubitainers. On special request we can provide a version which can sample into up to 5 individual sample bottles simultaneously or in a sequence.
The standard version works as time proportional sampler ensuring a representative sample. For applications with changing flow rates we also offer a flow proportional version.
Because of the ATEX regulations the sampler does not use electricity. All our samplers are pneumatically driven with normal working air between 6 and 8 bar. The samplers can be used under all weather conditions. The samplers including all fittings are made from stainless steel AISI 316. They are designed and produced to survive in a harsh environment.
Automatic Fuel Sampler Type 50
The waterproof sampler is equipped with a flushing tank and made of stainless steel. It does have a DNV type approval and complies with MARPOL Annex VI.
The sampler is also available as a wall mounted version.
The heavy duty sampler can be installed right on the manifold. It is fully pneumatic driven with bunker timer and does have an automatic stop function. This model is also produced in a low temperature version.
Automatic Fuel Sampler Type 70
This very advanced automatic Fuel Sampler, which can sample into 4 bottles simultaneously, is very popular on bunker barges but is also used on merchant ships.
The sampler can sample under all conditions even with very high negative pressure in the bunker line and does give you four most representative samples. This sampler is optional also available for 5 bottles.
The sampler is also available as a vertical wall mounted version.
In addition to the Type 50 specification it does come with a circulating pump to have a heating functionality. It does also have a DNV type approval and complies with MARPOL Annex VI.
