RZK01.1-315-NN

The Bosch Rexroth Indramat RZK01.1-315-NN is part of the RZK Heat Exchangers series, designed to support high-power frequency inverters with reliable thermal management. Featuring an outside cabinet mounting line and a 315 kW power rating for the associated frequency inverter, this unit provides efficient cooling for demanding industrial applications. With a brake resistor not built-in, it integrates seamlessly into systems that employ external braking solutions, ensuring optimized heat dissipation. The primary function of this heat exchanger is to absorb and dissipate the excess heat generated by inverter electronics, maintaining safe operating temperatures and enhancing system longevity.

In terms of technical specifications, the RZK01.1-315-NN operates under IP20 protection, safeguarding against solid objects larger than 12 mm while requiring unobstructed airflow through the exhaust passage. The unit has a mass of 32 kg, allowing for straightforward handling and installation on flat surfaces. It can withstand a peak power load of 2 x 270 kW for up to 0.1 seconds, making it robust under transient overload conditions. The calculated thermal time constant of 13.6 seconds ensures a rapid response to changes in heat load, preventing thermal runaway and preserving inverter performance.

Beyond basic cooling, the RZK01.1-315-NN offers durability and compatibility tailored for industrial settings. The outside cabinet mounting configuration simplifies integration into existing control panels, while the absence of a built-in brake resistor allows customization with third-party braking modules. Compliance with IP20 standards means the device must be installed in clean, indoor environments, but also benefits from reduced maintenance due to minimal ingress. By maintaining inverter temperatures within optimal ranges, this heat exchanger enhances energy efficiency, reduces wear on electronic components, and ensures continuous operation. Overall, the RZK01.1-315-NN provides reliable thermal management, contributing to improved uptime and lower lifecycle costs in automated industrial processes.
