LOC Series

Air Oil Cooler with AC Motor & Pump.

The LOC Air Oil Cooling System with AC-motor and pump provides cooling up to 45kW. Its robust construction makes it suitable for most applications and environments. Please use the Sizing Software on the Product Support Tab for proper cooler sizing.

The LOC cooling system with three-phase AC motor is optimized for use in the industrial sector. The system is supplied ready for installation and an integrated circulation pump makes it possible to cool and treat the oil in a separate circuit – offline cooling. The cooling system can also be equipped with a filter unit of the same brand. Together with a wide range of accessories, the LOC cooling system is suitable for installation in most applications and environments.

The maximum cooling capacity is 45 kW at ETD 40° C.

    Features and Benefits

    Quiet fan and motor -
    Integrated circulation pump produces an even flow with low pressure pulsations -
    Efficient and robust design which extends operating lifetime and reduces service and maintenance costs -
    Cooler matrix with low pressure drop and high cooling capacity -
    Easy to maintain and easy to retrofit in many applications -
    - -
    The correct working temperature produces a number of economic and environmental benefits: -
    - The hydraulic system’s useful life is extended
    - The oils useful life is extended
    - The hydraulic system’s availability increases – more operating time and fewer shutdowns
    - Service and repair costs are reduced
    - High efficiency level maintained in continuous operation – the system’s efficiency falls if the temperature exceeds the ideal working temperature
