Helidecks is certified for the manufacture of JET-A1 refuelling systems for helicopters boarded on mega yachts pursuant to the standards Insurance certificate Lloyd's Londra.
JET-A1 SYSTEM - MOD.21619
1.1) Transfer of the Jet-A1 fuel from an external supplier: before entering the storage tanks, the fuel is subject to the first stage of filtration – elimination of solid pollutants and separation of the water present (up to 0.5 microns).
1.2) The fuel is stored in removable tanks made of AISI316L stainless steel. Electronic probes transmit the level of the product in digital format; they also reveal the presence of water and, if necessary, block the start-up of the electric refuelling pumps before the product reaches the second separator filter.
1.3) Refuelling pumps: centrifugal or volumetric depending on the project conditions. Maximum efficiency and variable flow rates up to 300 lt/min, thanks to the inverter-controlled motors. They transfer the Jet-A1 to the second separator filter, and then to the monitor filter before reaching the hose; all of the filter containers are made of AISI316L.
1.4) Overwing refuelling of the aircraft with a dispensing pistol, or underwing refuelling with rapid pressurised attachment; motorised hose reel.
1.5) Defuelling: transfer of the aspirated fuel to a suitable tank. The volumetric pump ensures a flow rate of up to 120 lt/min.
1.6) The whole system is managed and controlled by the remote supervision system (SVR) via the colour LED display. The software makes available all of the parameters required for safe refuelling: fuel temperature, differential fuel pressure, flowrate, litres dispensed and in storage. The PLC controls the motorised valves, automatically setting the various circuits: refuelling, defuelling, recirculation, transfer and unloading.
1.7) The SVR interfaces perfectly with the yacht's monitoring systems; it can be installed on a PC with the following minimum requirements: operating system Windows 2000, XP Pro, Win7 and one available RS232 (COM) serial port.
