If using the RSL-526, be sure to provide a bypass circuit.*The cooling effects differ depending on the temperature and the water flow rate.■RSL-303● Economy coolers with a function-oriented simplified design can be installed in any orientation.● If using an air-cooling cooler, be sure to provide a bypass circuit. (The valve for bypass circuit is available.)*The cooling effects differ depending on the ambient temperature.■AN-355Modelϕ ARSL-303RSL-304RSL-305RSL-408RSL-415RSL-526*The required water flow rate is a calculated value if all maximum loads of each electric pump are converted into energy.Air-Cooling Oil Coolers 87.9114.3139.8Maximum Modeloperating pressure MPaADC-187-11K-1ADC-187-11K-2ADC-187-11K-3*Surge pressure is included.ADC-217-17K-3AN-305AN-355■RSL modelC Oil inletDimensionsC (Rc) D (Rc) 3/43/4951603/41-1/41801-1/2■ADC model2191770.98249255383455296430510322C Oil outletD Water outletD Water inletCompatible pumpMP-10 and lower models149MP-12 (H)MP-15 (H)MP-17 (H)MP-20 (H)212MP-40 and higher models265■AN modelConnection port sizeRc1871/22173601303/4410150■Hydraulic symbol of ■RSL-526 hydraulic symbolLBHBH1ABCDLm——113 liOlRequired water flow rateL/min121315183050Compatible Motor pumpspecificationsSingle-phase100 VACSingle-phase200 VACMP-4EMP-5EMP-6Three-phase200 VACMP-10MP-12 (H)MP-15 (H)RSL-303 to 415Approx. weightkg7.07.58.514.519.533.0■Hydraulic symbolApprox. weightCable lengthkg1.72.61619Oil CoolersWater-Cooling Oil Coolers Make-to-order product Make-to-order product 102
