DawMed International approached Tritec when they needed to design the control electronics and firmware for their new range of medical washing machines.

Now renamed as Wassenburg Medical, DawMed International are a leading manufacturer of medical washing machines, with a wealth of experience in the mechanical design and market requirements for these products. 

Hardware – Digital and Analogue

Tritec undertook the design of the two main PCB’s – the microprocessor control circuit and the switching board.

Both the microprocessor control circuit and a separate switching board were designed and laid out, and the prototype circuit boards built in-house at Tritec. 

Once the firmware for the microprocessor was written, system integration, commission and test were undertaken in conjunction with the client’s engineers.

Once the product was ready for volume manufacture, assistance was provided in handing over the PCB designs to specialist contractors for production runs.

Software – Embedded and PC

Embedded software (firmware) for the project was developed by Tritec’s software engineers, then tested on the prototype PCBs. 

Realising that the customer was likely to create a range of machines using the same set of electronics, our engineers developed the firmware with flexibility in mind. 

The relationship with the client has continued for over ten years. During this time the same circuit board has been designed into several new products, each with different software requirements. This early design decision for flexibility has allowed the firmware to be easily modified and extended, reducing both development time and costs for the client. 

“Tritec have helped to keep our products ahead of the competition”

Following on from the original project, PC software to communicate with and control several modules at once was commissioned from Tritec. The most recent variant of the products is controlled from a Windows based touch screen.
