Covering the complete power spectrum

Trouble-free assembly, simple to install and use Bosch Rexroth's frequency converters meet your engineering demands and your customer requirements through optimum, precise handling.

The EFC range provides an ideal variable frequency drive for pumps, fans and compressors up to 90 kW. Typical applications include building-material machines and technology; environmental and process engineering; food and beverage; manufacturing; general automation; machine tools; packaging machines; etc.

The 750 W – 160 kW Fe variable frequency drive is used in conveyor belts, agitators, extruders, pumps, fans and crushers/shredders. Typical applications include ventilation and A/C technology; pumps and fans; transport, storage and conveyor technology; machine tools; paper, printing and converting machines; etc.

The Fv VSD, which covers power systems up to 90 kW, is used in material transportation; hydraulics applications; rubber and plastics processing machines; paper, printing and converting machines; textile machines; and so on.

Bosch Rexroth's variable frequency drives support maximum connectivity through a Multi-Ethernet interface, including Sercos, PROFINET, EtherCAT, EtherNet/IP and Modbus TCP.

Using valuable energy efficiently

Rising energy costs and the need to move towards a more environmentally friendly production is compelling businesses to make use of or optimise machines that maximise energy efficiency across plant and factory automation systems. This is especially applicable in the field of drive technology.

Speed control of AC motors is essential in optimising their energy use by efficiently overcoming mechanical inertia. Bosch Rexroth's VFD range delivers a precise, efficient ramping of motor speed via controlled input frequency, reducing a process’s peak power demand, to deliver huge operational cost savings: up to 7 times lower energy consumption!

Bosch Rexroth variables frequency drives – on your doorstep!

Bosch Rexroth is one of the world’s leading variable frequency drive manufacturers, helping industries across the world maximise their production and plant efficiency through reduced energy consumption and increased motor life.

Tectra Automation provides OEM-level supply, integration and support of the company’s VFD range to the region’s industrial operations.

As Africa’s largest hydraulics and automation supplier, the Bosch Rexroth Africa has over 35 Group branches and 20 strategic distributors and sales partners throughout Africa. Each branch and distributor is strategically located near the region’s industrial centres. This means expert distribution and product and process support, on your doorstep!

Feature-rich motor speed control

Bosch Rexroth's variable frequency drives combine exceptional engineering quality with ease of use through a range of operational features that allow you to quickly set up the exact AC motor speed control parameters your application requires.

These features include a detachable VFD control interface, which can be mounted on the forward door of the electrical control panel. This gives the user access to the potentiometer, stop/start control buttons and display screen enabling quick parameter settings access and manipulation, convenient copy function, easy diagnosis and additional functions.

This detachment function also allows parameters to be copied and transferred between each VFD using the panel’s memory and copy function in installations that comprise multiple motor drives configured for identical tasks. Additionally, in the event of component failure, parameters can be retained from the old frequency converter through the simple insertion of its display panel into a new device.

Additional braking resistors are available for applications where the controlled motor is required to stop instantly, dissipating the voltage produced via electromotive force.

Tectra Automation retains large stockholdings of variable frequency drives up to 15 kW, with the higher-powered, larger units imported from Germany to order, with short delivery periods. With Bosch Rexroth's variable speed drives, Africa's industrial, factory and production line operations can attain precise, high-quality, and efficient machine automation, up to 7 times lower energy consumption!
