Product Description:
The RZK01.1-160-NN/S101 is a Heat Exchanger device from the company Bosch Rexroth Indramat to work with frequency inverters in industrial automation applications. It is designed for mounting outside the external cabinet enclosure. This placement helps in saving internal cabinet space. The unit supports frequency inverters with a power rating of 200 kW.
The nominal power capacity of the RZK01.1-160-NN/S101 heat exchanger is 2.5 kilowatts. It delivers maximum power up to 370 kilowatts for 0.1 seconds. The cooling power of the heat exchanger is 5 kilowatts. It operates through forced ventilation using an internal fan. The fan ensures consistent airflow across the unit components. The thermal time constant of this model is 14.3 seconds. Its housing design prevents the entry of external solid materials. The product maintains 95 percent efficiency under standard conditions. The overall resistance of the RZK01.1-160-NN/S101 heat exchanger is rated at 1.6 ohms. The heat exchanger does not include an external braking resistor. Its installation requires a minimum clearance of 100 mm above. It also needs at least 200 mm clearance below the unit. The total weight of the device is approximately 23 kilograms.
The RZK01.1-160-NN/S101 heat exchanger has a length of 542 mm for external fitting. The width of the housing is measured at 276 mm. The thickness of the structure is 510 mm. The heat exchanger handles thermal regulation during continuous inverter operation. It is compatible with systems needing high-capacity thermal control. The heat exchanger operates without internal malfunctions when maintained. Troubleshooting and malfunction procedures are detailed in the user manual. Instructions are included for safe and correct operational handling. The design is ideal for drive cabinets with external ventilation needs. The fan mechanism enables fast heat dissipation during active cycles.
