B&W ENGINEERING
Our shared successes.
Metering test rig.
For a major medical technology customer, we developed, built and successfully commissioned a test rig for the automatic dosing of minimal amounts of liquid for the diagnostics sector. What does the project have to do with a raindrop?
Infusion pump.
We were able to make a broad contribution to the development of this infusion pump family: harmonious collaboration through years of personal relationships, in-depth knowledge of requirements management, bringing together the different worlds of devices and disposables.

High-voltage distributor.
A project with positive tension! We took on the task of continuing the development of e-mobility in public transport with great enthusiasm. Functional safety was the main focus here, and was linked to further stakeholder requirements. We are very pleased to have been able to help make your next trip on an e-bus safe, reliable and comfortable!
metering test rig
A head start in hardware and software.
Diagnostic devices must work with the highest precision to reliably exclude incorrect measurements and subsequent incorrect treatment. To ensure this, thousands and thousands of tests have to be carried out in laboratories during the development of such devices (e.g. for blood sugar determination in diabetes patients).
For years, our customers have trusted us to develop test stations for the automatic dosing of very small quantities of liquid (as small as 1% of a raindrop). The most important requirements here were to carry out the tests quickly and safely and to control critical environmental conditions such as temperature and humidity.
The test station was integrated into a test station system developed by us. Thanks to its LabVIEW©-based features, this enables a variable system configuration as well as centrally controlled test and process plans. In this way, we have established flexible modality and a cross-system software solution at the same time. These contribute significantly to the efficiency of laboratories.
Highly precise, complex systems have many obstacles to overcome in development. B&W develops accordingly in a targeted and structured manner.
infusion pump
A wide variety of challenges.
An infusion pump works directly on people, including children. It is often used in hectic and life-threatening situations: in speeding ambulances or in intensive care units. Extreme reliability and precision are essential here. The requirements for an infusion pump are correspondingly diverse. We were responsible for the mechanical development with a correspondingly large number of interfaces in other areas. Starting with the industrial designer, through to electronics development and usability. Furthermore, precision in the most compact of spaces was the task. So we developed a device in which good design is ‘filled’ with the latest technology down to the last cubic millimetre. The infusion pump provides the required tightness, for example, against bursting infusion bags. It continues to work reliably even if it falls from a height of 1 m. And thanks to the significantly improved delivery accuracy that the device now has compared to its predecessor, the risk of incorrect dosing of highly effective drugs and their fatal consequences is significantly reduced. The result is a pump that exceeds today’s standards. We are proud to have developed the innovative technology of the future today!
The collaboration with B&W was a real win-win for all parties involved! And on top of that, we found true partners in the team.
high-voltage distributor
The positive tension project.
At the beginning of an electrified journey, there is a fully charged battery and the safe distribution of supply voltage and power in the on-board electrical system. In this truly exciting customer project, the task was to develop system components that ensure safe monitoring of the high-voltage charging voltage and the internal on-board electrical system for the other consumer modules in the vehicle – the high-voltage distributor. The high-voltage distributor, or HVV for short, is the first interface in the vehicle after the charging station and will be used in two versions in local public transport, more precisely in the 12-metre solo bus and the 18-metre articulated bus, for the product launch. The plan is to use 800V on-board power and up to 250A charging current in the first stage of development. The development included the hardware, software and mechanical engineering, with a focus on functional safety: thanks to its 100% passive cooling, the HVV can be operated decoupled from the vehicle cooling system, thus offering greater flexibility in vehicle design. The placement in the vehicle also serves this purpose: the current version of the HVV is mounted directly on the vehicle roof. This maximises the amount of space and comfort for the passengers. To reconcile function and comfort in this way, we ensured that an absolutely robust and waterproof housing of the HVV was created that provides optimal protection against the given environmental influences. To implement the safety requirements, the diagnostic functionality was also implemented independently on a hardware basis, in parallel with software monitoring, which enabled an efficient implementation of the system design. In parallel with the development, the customer’s requirements management was maintained and the test progress was logged. For developers, it is the greatest recognition to see the customer satisfied and their own concept become reality. With this in mind, we are proud that, thanks to our hands-on mentality and a high degree of parallelised work, the first vehicles with the high-voltage distributors we developed were successfully released and delivered to companies in the shortest possible time.
B&W quickly put themselves in our position and understood our challenges. This allowed us to make great progress and achieve success.
