RZK01.1-132-BW

The RZK01.1-132-BW, Bosch Rexroth Indramat, RZK Heat Exchangers is engineered as a dedicated thermal management solution for frequency inverter applications. Designed specifically for integration with RD 500 series drives, it provides efficient dissipation of waste heat to maintain optimal drive performance. The exchanger’s outside cabinet mounting configuration ensures straightforward installation on external panels, preserving internal cabinet space. Strict adherence to safety guidelines—including a minimum ten-minute cool-down before service—is required to avoid contact with hot surfaces and ensure operator protection.

With a 132 kW power-handling capacity, the unit delivers 4 kW of cooling power while weighing just 16 kg. The built-in braking resistor features a 2.2 Ω resistance, supports 2 kW continuous dissipation and withstands 270 kW peak surges with a 13.6 s thermal time constant. Installation is simplified via pre-drilled templates and standard coolant hose connections for seamless integration into existing fluid circuits. Multiple frequency converters may share the heat exchanger provided total converter losses remain within the 4 kW cooling envelope.

Engineers benefit from rapid plug-and-play integration, consistent temperature control and extended inverter service life. The external mounting design frees valuable internal cabinet real estate and streamlines routine maintenance without system downtime. Backed by a one-year global warranty, the RZK01.1-132-BW ensures reliable operation and peace of mind in demanding industrial environments.
