Specific cooling capacity Pspez [W/K] Cooling capacity Flow rate Q [l/min] The specific cooling capacity indicated in the graph was determined on the test bench, test oil ISO VG 46, oil-inlet temperature 60°C. The actual cooling capacity may deviate by approx. ± 5 % depending on the installation site and other operating parameters.

Installation instructions If possible, the heat exchanger should be integrated into the system with suitable hydraulic hoses. In the case of rigid piping, compensators are one way of eliminating introduction of forces via the piping. Pressure peaks in the system can lead to fatigue failure of the heat exchanger, even if they are below the permissible operating pressure. The frequency of the peaks is the influencing variable. 7 Support of electric engine

Partial flow cooler unit for industrial use Series ACIP The new cooler system ACIP is optimised for a wide range of hydraulic applications. An integrated motor pump unit makes it possible to cool the oil efficiently and continuously in a separate circuit. The cooling process is working independently from the operation condition of the main hydraulic power unit. • Oil-air cooler ACI with motor & pump in one unit • Gear pump, operating pressure: 4 bar • Continuous cooling process • Permissible viscosity range: 10 - 300 mm2/s • Easy to retrofit in existing systems • Extension of oil life due to...

Highest cooling capacity and • Low pressure drop over the connectors • Optimised plate design • Compact dimensions, low water consumption and low Delta T • Highly efficient heat transfer due to turbulent flow (high k value; P=k*A*Delta T) • Self cleaning effect inside the cooler due to equally distributed and highly turbulent flow Technical data

DOC® Brazed plate heat exchanger Selection diagram kW HP The diagram • is based on an oil temperature of 60°C and water temperature of 20°C. For an oil temperature of 50°C, multiply with the correction factor of 0.7. For other water temperatures, please see the correction factors on the right side. • is calculated for two different oil / water flow rates: 2:1 and 4:1. This means that for every litre of oil circulated through the oil cooler, a minimum of 0.5 litres (2:1) or 0.25 litres (4:1) of water must be circulated to agree with the data in the diagram. • is based on oil (ISO VG 32). For other...
