Hagglunds Oil Cooler Used for DOb,DUe drive unit, Bosch Rexroth DUe drive unit provides the hydraulic motor(s) with required hydraulic oil flow and pressure together with system control functionality.
Hagglunds Oil Cooler Function:
• The air-oil cooler consists of a fan driven by an electric motor, blowing air through the cooler matrix.
• The cooling pipes are made by extruded aluminium sections. They are flat with narrow short sides to expose a maximum heat-emitting area and to allow low air pressure drop.
• All coolers have a 4 bar(58 psi) by-pass function to limit the oil pressure in the cooler.
• The electric motor is a 3-phase asynchronous motor.
Recommended max temperature
For oil viscosity 68 cSt the maximum recommended temperature of the inlet oil is limited to 63 °C (145 °F) and for
100 and 150 cSt limited to 66 °C (151 °F).
The temperature is limited by:
• The life of the hydraulic motor
• The recommended min. viscosity of the hydraulic fluid
Electric motor:
• Insulation: Class F
• Temperature rise: Class B
• Protection standard: IP55
