Oil/Air Cooler Units COMPLETE OIL / AIR COOLER SYSTEM Standard series WITH AXIAL FAN FOR EL Type INDUSTRIAL APPLICATIONS. Application These high performance coolers with axial fans are suitable for hydraulic cooling applications with both return line and off line versions available. Typical applications include: industrial power units, lubrication systems (i.e. gearboxes) and machine tools. OK-EL Product Features Large Range Of Sizes 16 Bar Dynamic Pressure Rating Modular Construction EL coolers use high efficiency axial fans and strong cooling elements to achieve maximum performance. Many models are available with medium or high speed fans and the modular design allows the addition of circulation pumps and filters when required. OKA OKAF Product Features Off-line Complete Package. Avoids return line pressure flow problems. Allows integration of quality Hydac filtration. The OKA version with integrated oil circulation pump allows the cooler to create an off-line cooling system that can also provide high quality filtration if required with the OKAF model having the latest high performance Hydac filter also integrated. The advantages of the off line cooling system include stable cooling (and filtration) performance irrespective of variations in flow and duty for the main hydraulic circuit. This allows the cooler to be sized to suit the heat load and not the maximum return line flow of the main circuit. A further advantage is that the off-line cooler is completely isolated from surge pressures in the return line that can potentially damage the cooler. Cooling range 2-108 kW at ∆T 40 °C Compact, efficient and powerful Standard motor flange B5/B14 Simple disassembly of components Test procedure certified following EN 1048 OIL/AIR COOLER
