Modern Duplex Filters for Large Engines
Modern Duplex Filters for Diesel, HFO and Lube Oil Filtration has a key role to play in developing and optimising heavy engine technology. The quality of the fuel has a direct effect on engine emissions. Particles in the fluid damage the enhanced fuel systems required to comply with the emissions standard. The tendency in engine technology development towards optimising consumption, exhaust gas and costs while increasing the performance characteristics continues unabated. The increasingly complex injection systems of the heavy engines work on the premise that the fuel will be virtually free of contamination particles. To offer a most efficient filtration to every large engine HYDAC provides different filter and filter element designs for different applications depending on the fluid type that is employed. We supply certified quality Selection of the modern duplex filter type depending on the fluid: Lube Oil Preference filter On inquiry Initial-Δp (@ 50 mm²/s): 0.3 bar qs-value: 6.0 l/h*cm² (W/HC), 2.4 l/h*cm² (ON/PO) Alarm: 0.8 bar (W/HC), 1.5 bar (ON/PO) RFLD Connection Optimicron Power (ON / PO) ß25(C) > 200 Wire Mesh (W / HC) 10 µm Wire Mesh (W / HC) 25 µm / 34 µm Filter size DN Flow rate [m 3 /h] 111 25 2.5 3.5 3.5 241 40 6.1 9.0 9.0 261 40 7.8 9.2 9.0 331 50 8.0 14.2 14.2 501 50 12.2 14.2 14.2 661 65 17.1 19.2 19.2 851 65 17.4 19.5 19.5 951 80 25.8 30.6 30.6 1301 80 27.6 31.8 31.8 2701 150 90.0 130.3 130.3 Diesel Fuel Initial-Δp (@ 4 mm²/s): 0.3 bar (Optimicron ), 0.1 bar (Wire Mesh) qs-value: 1.0 l/h*cm² (Optimicron ), 2.0 l/h*cm² (Wire Mesh) Alarm: 1.2 up to 1.5 bar (Optimicron ), 0.8 bar (Wire Mesh) RFLD Connection Optimicron FuelFine (ON / FF) ß4(C) > 6000 Optimicron Power (ON) ß5(C) > 200 Wire Mesh (W/HC) 10 µm / 25 µm / 34 µm Filter size DN Flow rate [m 3 /h] 111 25 1.0 1.0 2.0 241 40 2.5 2.5 5.0 261 40 3.3 3.3 6.2 331 40 3.3 3.3 7.4 501 40 5.1 5.1 11.3 331 50 3.3 3.3 7.4 501 50 5.1 5.1 11.3 661 65 7.5 7.5 16.5 851 65 9.6 9.6 21.2 951 80 11.2 11.2 23.0 1301 80 15.5 15.5 32.2 HDMD / HDPD Connection Dieselmicron 1 µm Dieselmicron 7 µm Filter size DN Flow rate [m 3 /h] HDMD 2200 M33x2 4.0 (2.0) 1) HDPD 1800 M33x2 1.8 (0.9) 1) 1) max. flow rate in dual mode (in single mode) HFO Fuel (and Diesel Fuel) Initial-Δp (@ 150 mm²/s): 0.1 bar qs-value: 1.0 l/h*cm² Alarm: max. 0.8 bar 2 RFLD Connection Wire Mesh (W / HC) 10 µm Wire Mesh (W / HC) 25 µm / 34 µm Filter size DN Flow rate [m 3 /h] 111 25 1.0 1.0 241 40 2.5 2.5 261 40 3.1 3.1 331 50 3.7 3.7 501 50 5.6 5.6 331 50 3.7 3.7 501 50 5.6 5.6 661 65 8.2 8.2 851 65 10.6 10.6 951 80 11.5 11.5 1301 80 16.1 16.1
