The R911395732 Heat Exchanger HAH02.1-WA012-020-15-S1-N-48-S004 is designed to efficiently transfer the power dissipation of water-cooled components in a drive system. It operates on the principle of transferring to an external cooling medium. In the case of water-water heat exchangers, it can be used for process water or in heat recovery systems. Water-air heat exchangers transfer the dissipated heat into the ambient air. Original Bosch Rexroth product with local support through CreatX Technology SRL. Suitable for IndraDrive ML, HMU05.
