Air Cooler Mobile OK-ELD 0-6 with DC motor

Transcription

1 ir ooler Mobile OK-ELD 0-6 with D motor Symbol General The OK-ELD air cooler series is designed specifically for mobile hydraulic applications where high performance and efficiency are required and physical size must be minimized to allow easy installation. Product Features These coolers use a combination of high performance cooling elements and high capacity, long life D electric powered fans to give long trouble free operation in arduous mobile hydraulic applications. The compact design allows the coolers to fit most equipment and provide the highest cooling performance in heat dissipation whilst minimizing space required. l ompact, efficient, high performance l ooling range 2-34 kw l D motors in 12 Volt and 24 Volt with motor lifetimes up to 16,000 hours pplication Field Hydraulic systems in mobile machines and vehicles, such as l Mobile cranes l oncrete mixers and pump trucks l Road paving machines l onstruction machines (excavators, wheel loaders) l gricultural machines l Municipal machines Operation Data Fluids Viscosity Temperature range Pressure resistance of the cooling element Fan Motor Noise levels ccessories l Oils (mineral oils, synthetic oils, high viscosity oils, biological oils, phosphate ester) l Water-glycol (cooling fluids) l HF pressure fluids 2,000 mm²/s (standard) l Minimum / maximum ambient temperature: - 20 to + 40 (standard) l Minimum / maximum temperature of the medium: + 20 to Please contact the technical sales department in the event of deviating temperatures. Notice! Fan at max. speed (max. volume of air) must be avoided when operating a cooler at which the temperature difference between the medium inlet at the cooler and the ambient temperature can be greater than 50. Quick changes in the temperature of the cooling element material can lead to a significant reduction in service life or to direct damage of the cooling element due to thermal shock. Please contact the technical sales department to receive information about controlled fan drives. l Dynamic operating pressure: 16 bar l Static operating pressure: 21 bar xial fan in suction version (standard) xial fan in pushing version on request (note: approx. 10 % less cooling capacity) l D motor l 12 V / 24 V l Protection class IP68 l Insulation class F Other versions on request. See technical data The noise levels are only reference values as the acoustic properties of a room, connections and reflection have an effect on the noise level. l Integrated pressure bypass valve (IP) or integrated thermal pressure bypass valve (IT) (cannot be retrofitted, also see options) l rushless fan l Electronic speed control (ES) l Thermostats l ir filter grid or air filter mat l Vibration damper 1

2 Options Integrated pressure bypass valve (IP) / Integrated thermal pressure bypass valve (IT) The bypass channel is integrated in the cooling element. If a particular pressure is exceeded, the IP opens the bypass channel, thereby protecting the cooling element from too high a pressure. Furthermore, the IT only opens the cooling element path once a particular temperature has been reached.
