The WIWA DUOMIX PU 540 is another new addition to the DUOMIX PU series. This pneumatic, compact, mobile and versatile system processes almost all polyurethane foams and fast reacting polyureas.

The newly designed, exceptionally efficient heater is based on proven and patented technology for gentle material heating. Only the exact quantity required of each individu­al component is brought quickly and economically to pro­cessing temperature.

The new design of the dosing pumps allows a further impro­ved material flow. The wear of moving parts was thereby considerably reduced.

>> Changing the mixing ratio is a matter of minutes by sim­plified exchange of the material pumps. More than 200 dif­ferent mixing ratios can be achieved in this way. <<

The layout of the WIWA DUOMIX PU 540 is clearly structured to allow the user to work quickly and comfortably. The con­trol panel was deliberately kept simple.

The increased volume output of the WIWA DUOMIX PU 540 is ideally suited for high-build and high-coverage appli­cations. The latest aspects of the EU machine directives have been incorporated in the design in order to ensure the highest safety standard. Two feed pump versions are available, diaphragm pumps and newly developed piston pumps, which can be easily transported and stored in the integrated holders. A wheel kit converts the standalone frame to a rolling chassis in minutes.

The WIWA DATALOGGER is an ideal supplement for quality management. All processing parameters, setting values and the alarm history can be read and saved via Wi-Fi with the help of commonly available smartphones, tablets or PCs.
