Introduction

The accepted method of checking the cleanliness of aviation fuel is the 'clear and bright' test, where fuel is swirled around in an open bucket or clear glass jar and visually inspected. However this procedure carries the risk of sample contamination from the elements or from dirty sample points. There is also a high probability of fuel spillage and contact with operations staff. The Closed circuit Sampler 'CCS' has been developed to overcome these problems and actually improives sampling procedures, and as a result it is in widespread use with refueling companies all over the world. JIG Bulletin 123 & JIG TID No 3 detail the design, use, and maintenance of the CCS. With this in mind, the manufacturer has developed this 2026> updated version to assist with visual appearance checks.

Description and Operation

The CCS consists of a clear glass tube fitted with a white epoxy coated conical base to assist in the detection of dirt and water, sediment and suspended matter. The CCS is fitted with a hinged cover that fully opens to allow for easy cleaning. The base incorporates a tangential inlet port to promote vortexing of the incoming fuel, and a close coupled stainless steel drain valve. The inlet port should be connected to the sample points using small bore tubing (typically 10mm diameter), and we recommend fitting spring close inlet valves close to the CCS to control the filling operation, which we can also supply. The drain port should be connected into the hydrant dispenser dump tank, depot product recovery system, or storage tank using 20mm inside diameter pipework. It is recommended that the CCS is located such that gravity drainage is possible. If not, we are able to supply a rotary pump and non return valve to drain the CCS.

When fuel is drawn into the CCS under pressure from the sample points the tangential inlet port promotes vortexing of the incoming fuel. This concentrates and contamination in the center of the base making detection very easy. After the fuel has been visually inspected the drain valve is opened to release the sample. Internal cleaning of the CCS is accomplished through the hinged lid.

A number of options are also available;

• A secondary chamber for Hydrometer and Thermometer for density and temperature checks can be provided. The secondary chamber fills at the same rate as the main chamber, and crucially, does not affect the vortex required to conduct the visual appearance check.
• External fitting for Shell Water Detector Capsules for Jet Fuels, Box of 80 Capsules or Velcon Hydrokit.
• The CCS is available with BSPP or NPT threads.
