Liquid cooled power resistors

Liquid cooling is a highly efficient method of dissipating energy from a heat source. The LCPR series liquid cooled power resistors developed by the KRAH Group make ideal use of this, allowing thermal energy to be almost completely assimilated by the coolant and only a fraction of the heat to be dissipated across the housing surface. The innovative concept also includes six single resistors which can be freely connected and are immersed in the coolant. The advantages of this fluid dynamics optimization include even thermal distribution and extremely low pressure loss.
