The following tables may be used to quickly select a TL-cooler. The data is based on the assumption that oil inlet temperature does not exceed 70 °C for hydraulic and 110 °C for lubrication applications. Please use the following heat rejection figures if no details are available: - Agricultural and construction machinery: 1/3 of Diesel engine power - Hydraulic pumps driven by an electric motor: 1/3 of electric motor power Heat rejection [kW @ 40 °C ambient temperature] Building Machines, Compressors, Cranes, Crawlers, Drills, Excavators, Graders,

For a more detailed and customised cooler selection exact temperatures and flows are necessary. Please select your cooler according to the example on page 10 or seek advice from AKG or its representatives.

The pressure drop curves are based on a viscosity of 30 mnf/s = 30 cSt. Please use conversion factor f from page 11, to calculate pressure drop at other viscosity's.

To select a cooler for your application, the following data is required: • Heat rejection: • Oil flow: • Oil inlet temperature: • Cooling air flow temperature: Alternative terminology is dissipation Circulating oil flow determines the cooler size Temperature of the oil entering the cooler Air temperature at cooler face before entering matrix 1.

The pressure drop curves on pages 9 are based on a viscosity of 30 mm2/s = 30 cSt. Please use conversion factor f to calculate pressure drop at other viscosities. Example: Pressure drop of type TL4 is 0.75 bar @ 90 l/min and 30 mm2/s. Assume an oil type ISO VG 46 is used @ 60 °C having a viscosity of 20 mm2/s. To calculate new pressure drop multiply 0.75 bar by f = 0.75 to obtain the actual pressure drop 0.6 bar approximately. Chaffcutters, Combines, Forestry Machines, Harvest Machines, Tractors
