Starting Air Compressor · Compressors
Hamworthy 4TG12 is a marine starting-air compressor. It is normally installed in the engine room close to the starting-air receivers and associated cooling, drainage and control equipment. Its primary purpose is to recharge the compressed-air receivers used for starting large marine diesel engines. Compared with service-air machinery, starting-air compressors are part of the engine-starting safety chain and are normally arranged with dedicated pressure, temperature and lubrication protection. The supplied record already contains the available concise model or rating information, so those existing figures are not duplicated here and no additional meaning is inferred from the model code. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.
What our service work and the manufacturer documentation say about keeping this model running.
Inspect filters, valves, pistons or compression elements, lubrication, intercoolers, aftercoolers, drains, relief devices, non-return valves and foundations. Check receiver charging behaviour and compare cylinder or stage temperatures for imbalance. Test automatic start/stop and safety trips under an approved procedure. Refer to the manufacturer documentation for the exact figure for valve clearances, pressures and wear limits.
Carry suction filters, valve plates or valve kits as applicable, piston-ring or seal kits, approved lubricant, belts or coupling parts, drain-valve parts, gaskets, pressure switches and control relays.
