4 Selection Procedure Performance Curves are based on 50 SSU oil entering the cooler 100 F higher than the ambient air temperature used for cooling. This is also referred to as a 100 F ntering Temperature Difference (TD). STP 1 Determine the Heat Load. This will vary with different systems, but typically coolers are sized to remove 25 to 50% of the input nameplate horsepower. (xample: 100 HP Power Unit x.33 = 33 HP Heat load.) Convert HP to BTU/MIN: HP x 42.4 = BTU/MIN STP 2 Determine ntering Temperature Difference (TD). Desired oil entering cooler F Ambient air temp. F = Actual TD STP 3 Determine Curve Horsepower Heat Load. nter the information from above: TD Temperature Correction Factor: 100 x Cv BTU/MINcorrected = Input BTU/MIN x Desired TD nter curves at oil flow through cooler and curve horsepower. Any curve above the intersecting point will work. STP 4 Determine Oil Pressure Drop from Curves: l = 5 PSI n = 10 PSI s = 20 PSI = 30 PSI H = 50 PSI Multiply pressure drop from curve by correction factor found in oil P correction curve. xample Fluid = SA 20 oil System lectric Nameplate Horsepower = 300 HP ntering Temperature = 200 F Ambient Temperature = 75 F Flow Rate = 200 PM b Determine heat load. enerally, about 25% to 33% of the system horsepower is removed. 300 HP x 0.33 = 99 HP b Since the graphs have the heat load in terms of BTU/MIN, the units must be converted. 99 HP x 42.4 = 4,199 BTU/MIN b Calculate the entering temperature difference (TD). The TD is the inlet oil temperature minus the entering air temperature. TD= =125 b Calculate the corrected curve heat load. Corrected curve heat load = actual heat load x (100/TD) x Cv (viscosity correction factor obtained from the Cv table). 4,199 BTU/min x (100/125) x 1.02= 3,426 BTU/MIN b Find the intersection point between the corrected heat load and flow rate on the performance curves. Any curve above this point will work for this application. Usually the smallest cooler is most desired. In this case the intersecting point on the single pass graph indicates that the OCA-450 will suffice. b The pressure drop should be found next. Find the point on the curve that is directly above the intersecting point. This point on the curve indicates the pressure drop. P 6 PSI b These curves are made for SA 10 oil entering at 200 F. Therefore, the pressure drop needs to be corrected. The 1.24 is the pressure drop correction factor obtained in the Cp table. b P CORRCTD = 6 x 1.24= 7.44 PSI C V Viscosity Correction Factors ntering Liquid Temp SA 5 SA 10 SA 20 SA 30 SA 40 ISO 22 ISO 32 ISO 46 ISO 68 ISO 100 ISO 150 ISO 220 ISO 320 C P Pressure Drop Correction Factors MIL-L 7808 ster Polyglycol Phosphate 50% ntering Liquid Temp SA 5 SA 10 SA 20 SA 30 SA 40 ISO 22 ISO 32 ISO 46 ISO 68 ISO 100 ISO 150 ISO 220 ISO 320 MIL-L 7808 ster Polyglycol Phosphate 50% thermaltransfer.com ttp-sales@apiheattransfer.com

6 The OCA Advantage T-BAR is a flexible design, high performing, and a costeffective aluminum solution. Advantages Tubular Micro Channel xtrusion (T-BAR) T-BAR is manufactured with Alloy 1100 aluminum micro channel and bars, with Zinc flame-sprayed extruded tubes and zinc alloy coated fins, in our patented in-house tube-to-bar brazing process using a Nocolok CAB (Controlled Atmosphere Brazing) brazing technology furnace. Because our tubes are a solid extrusion, T-BAR is very robust with no tube seams to fail and leak. Flows high viscosity fluids T-BAR provides advantages and value far beyond typical aluminum core designs. xtruded tubes for a leak free design Low pressure drop due to absence of internal turbulator Resistance to fouling transfer fluids without plugging reat for cooling cutting fluids or gear lube Resistant to salt spray and salt air Standard Zinc infused/coated core & fins for up to 10 times protection in salt conditions Domestic built Optional core for BOL model HIH-PRFORMANC LOW-CLOIN T-BAR COR IN OCA ASSMBLY T-BAR Manufacturing Process CUTTIN STATIONS 1: CUT XTRUDD ALUMINUM TUBIN FLUX STATION 4: FLUX COR UNIT TO PRPAR FOR BRAZIN 2: CUT SPACR BARS STACKIN STATION 3: STACK ASSMBL TUB & BARS TO FORM COR UNIT thermaltransfer.com COOL-DOWN UNIT 7: COOL FURNAC 5: PR-HAT WLDIN STATION 8: WLD TANK, PORTS & BRACKTRY TO COR 6: BRAZ 1200 F ttp-sales@apiheattransfer.com
