RZK01.1-200-BW

The RZK01.1-200-BW, Bosch Rexroth Indramat, RZK Heat Exchangers unit is an internal heat exchanger designed for use with RD 500 drives whenever cooling type R is selected. This compact accessory features an integrated braking resistor and mounts directly to the outside of a cabinet for streamlined installation. It comes factory-set to monitor the resistor via parameter P0036: Standard, ensuring seamless commissioning and operation. Engineered by Rexroth Indramat Bosch, the device complements existing drive electronics without requiring additional control hardware.

Detailed specifications include a Built-In Brake Resistor with a resistance of 1.6 Ohms and a nominal power rating of 2.5 kW, plus a peak power capacity of 370 kW available for 0.1 s. The heat exchanger supports a Power Data of Frequency Inverter: 200 kW and features a Line: Outside Cabinet Mounting arrangement for straightforward retrofitting. Its resistor exhibits a thermal time constant of 14.3 s, and Bosch recommends a minimum clearance of 200 mm above and 100 mm below the unit to guarantee optimal airflow and cooling performance. All parameters are detailed in load diagrams provided in the product manual for precise braking time calculations.

Integration with Bosch Rexroth converters offers real-time monitoring of resistor temperature and load, automatically shutting down the drive if thermal limits are exceeded. Worldwide shipping is supported, backed by a one-year warranty and installation by qualified personnel to ensure reliability. Ideal for high-power frequency inverter applications, the RZK01.1-200-BW enhances system uptime and simplifies maintenance in demanding industrial environments.
