Oil / Air Cooling Units for mechanical engineering and mobile hydraulics ViFlow Finland Oy • Kauppakartanontie 7 A 1 • 00930 Helsinki, Finland • tel. +358 40 178 0920 • fax +358 9 4789 2800 [email protected] • www.viflow.fi Oil / Air Cooling Units, OKAN Series A wide range of standard units can now meet most of the applications in the field of oil/air cooling units. 16 sizes of the OKAN series are available with a heat dissipation of max. 2.5 kW/K, subject to market requirements, in one- or multi-pass design. Furthermore, for plant engineering and for series producers we are developing project related special designs. Basic element is an aluminium cooler core. Oil tubes are fitted with a turbulence element to ensure an optimum heat transfer. To achieve high cooler capacity the fin arrangement, fan blades and power of engine are harmonised aerodynamically and thermally. OKAN II Frame design for all common applications OKAN III 65 mm core depth, specially for mobile hydraurics Applications Operating data • Cooling of oils, hydraulic fluids and emulsions using ambient air - especially in the field of mechanical engineering, plant engineering, building machinery and the special vehicle industry. • Used as additional cooler at peak load range (summer) • Where water is not available or piping is too expensive • max. cooling capacity: approx.100kW resp. 2.5 kW/K • max. operating temperatures: for oil 120°C, for emulsion 90°C • max. operating pressures: 16 bar • ambient temperatures: -20°C up to +40°C • frontal areas: 0.05 up to 1.00m2 • fan drives: three-phase motor DC motor hydraulic motor Advantages of FUNKE-OKAN series • effectively low costs per kW heat dissipation • sturdy, compact design with high standard of quality • extensive accessories and combinations available • customer-specified design • low installation and operating costs • free choice of installation • best availability at long service life • almost maintenance free Data required for offer preparation • • • • • • cooling capacity (kW) oil flow (l/min) oil inlet temperature ambient temperature max. allowed noise level type of motor / voltage / frequency Optimum equipment variants • complete system incl. temperature control and pump • explosion protected design • sea air resistant surface protection • air filter for cooler core ViFlow Finland Oy • Kauppakartanontie 7 A 1 • 00930 Helsinki, Finland • tel. +358 40 178 0920 • fax +358 9 4789 2800 [email protected] • www.viflow.fi Technical data, OKAN II series 1 Cooler block 1.1 Box 3 Guard 1.2 Turbulator 4 Three-phase AC motor 1.3 Cooling fin 5 Fan shroud 1.4 Side member 6 High-performance fan 2 Support 7 SAE counter flange Chart data applying to design with three-phase motor MODEL Frontal Area (m2) 2 3 4 5 6 7 8 9 10 11 13 14 0.050 0.080 0.100 0.160 0.200 0.250 0.315 0.400 0.500 0.600 0.800 1.000 16 23 25 35 38 46 51 68 78 138 177 189 295 380 425 350 440 470 350 510 470 455 610 540 455 710 540 550 720 575 550 850 575 660 850 635 820 870 635 820 1020 710 970 1170 810 970 1360 810 61/49 79/67 59/47 70/58 84/72 59/47 70/58 84/72 57/45 64/52 75/63 - 58/46 65/53 75/63 - 62/50 70/58 82/70 - 66/54 72/60 81/69 - 68/56 77/65 89/77 - 71/59 79/67 90/78 - 69/57 76/64 86/74 - 77/65 85/73 - 77/65 86/74 - Weight ca. kg Dimension mm B H T Noise level 1m/7m dB(A) 750 min-1 1000 min-1 1500 min-1 3000 min-1 Specific heat dissipation P01 P01 = = Pv tÖIE - tLE 20 60 - 30 = 0.67 (kW/K) (kW/K) P01 : Specific heat dissipation (kW/K) Pv (kW) : Power loss tÖIE : Oil-inlet temperature (°C) tLE : Air-inlet temperature (°C) · VÖl : Oil flow (l/min) ViFlow Finland Oy • Kauppakartanontie 7 A 1 • 00930 Helsinki, Finland • tel. +358 40 178 0920 • fax +358 9 4789 2800 [email protected] • www.viflow.fi Technical data, OKAN III series design with three-phase motor design with DC motor MODEL III - 1 III - 2 III - 3 III - 4 Frontal Area (m2) 0.08 0.11 0.15 0.21 15 21 25 31 320 423 400 368 475 425 420 543 425 500 608 425 63/51 78/66 58/45 68/54 85/70 68/48 72/58 87/74 65/52 76/63 - Weight ca. kg Dimension mm B H T Noise level 1m/7m (dB (A)) 1000 min-1 1500 min-1 3000 min-1 P01 (kW/K) Specific heat dissipation P01 P01 = = Pv tÖIE - tLE (kW/K) 3.04 1500 min-1 3.03 3000 min-1 3.04 1000 min -1 20 60 - 30 = 0.67 (kW/K) 3.02 3000 min-1 P01 : Specific heat dissipation (kW/K) Pv (kW) : Power loss tÖIE : Oil-inlet temperature (°C) tLE : Air-inlet temperature (°C) · VÖl : Oil flow (l/min) 3.01 1500 min-1 3.02 1000 min-1 3.01 3000 min-1 3.03 1000 min-1 · VÖl (l/min) ViFlow Finland Oy • Kauppakartanontie 7 A 1 • 00930 Helsinki, Finland • tel. +358 40 178 0920 • fax +358 9 4789 2800 [email protected] • www.viflow.fi Sample applications Truck agitator, Liebherr Oil supply plant, Schupp Beat uprooting loader, Holmer Snow bully, Kässbohrer Serial production of oil/air coolers with integrated oil containers Mobile deep drilling equipment, Hütte & Co ViFlow Finland Oy • Kauppakartanontie 7 A 1 • 00930 Helsinki, Finland • tel. +358 40 178 0920 • fax +358 9 4789 2800 [email protected] • www.viflow.fi Cooling unit turbo-copling, Voith Truck agitator, Liebherr ality and certificates Quality means safety.
