Transcription

1 Cooler Industry OSC / OSCF 0- Symbol General The low noise coolers of OSC / OSCF series are mostly used in small and medium hydraulic systems. Compact and efficient they offer high performance with a low noise level in a modular design. The OSC models with integrated oil circulation pump provide efficient offline cooling of the hydraulic fluid. The OSCF models with integrated (insideoutside) filter provide additional filtration, using the latest high capacity filter dirt holding development. Product Features Installed off-line, the OSCF provides efficient cooling and filtration of the hydraulic fluid regardless of the duty cycle of the hydraulic system. nd, the cooler can be sized perfectly to the necessary cooling performance, rather than to the maximum return-line flow rate. Off-line installation will also eliminate flow variances of the hydraulic fluid and resulting pressure spikes which potentially could lead to a premature cooler failure. Operation Data Fluids Viscosity Temperature range Fan Motor Pump Noise levels Oils (mineral oils, synthetic oils, high viscosity oils, biological oils, phosphate ester) 00 mm²/s Minimum / maximum ambient temperature: -0 C bis +0 C (Standard) Minimum / maximum temperature of the medium: +0 C bis +90 C Please contact the technical sales department in the event of deviating temperatures for applications with water-glycol. Notice! Fan switching frequency at max. fan 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 0 C. 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. Radial fan in suction version (standard) Three-phase motor Efficiency class IE (only 0.7 kw) Protection class IP Insulation class F Other versions on request. Screw pump Operating pressure: max. 0 bar Negative suction pressure of pump: max. -0, bar 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.

8 Note: We recommend maintaining a minimum distance to ensure an unimpeded air inlet and air outlet. This is half the height of the cooling element (/). nything below the minimum distance can influence the cooling capacity and the noise emissions.
