Relentless innovation – That is what makes BÖWE different

Ever since dry cleaning machines have been in existence, the problem of distillation boil over (also: black-over) has been known in the industry. Due to the addition of low temperature boilers such as water, high humidity, dosing additives and substances removed from the garments during the dry cleaning process, the boiling behaviour of the solvents and the low boiler mixture can change. This results in froth and a black-over of the distillation. This problem is particularly known in the case of alternative solvents, which have been used more and more in the last few years.

BÖWE decided to tackle this situation and developed a new photoelectric sensor. During the distillation process, the surface of the liquid in the distillation is monitored. If there is increased bubble formation, the sensor detects this situation and automatically breaks the vacuum for a short time. This leads to an increase in the boiling point and a collapse of the foam head. Black-over and dirt transfer are thus prevented. This eliminates the need for annoying and expensive cleaning of the water separators and clean tanks, which lead to odour formation if poorly maintained. In addition, energy-intensive distillation of contaminated tank contents is no longer necessary which saves a lot of energy, time and cooling water.

As has been the case for decades, BÖWE has once again set a milestone in textile cleaning technology with this innovation. Register cooling in the 1950s, drying controller device in the 1960s, refrigeration technology in the 1980s, fully closed textile cleaning machines in the 1990s, cataphoresis coatings on the components to prevent lint build-up from 2010 onwards, turbidity measurement for automated distillation in 2016 and now the black-over protection of the distillation are just a few examples of innovations that have found their way into the industry through BÖWE.

The new developments can be viewed and tested in the BÖWE showroom in Sasbach in the Black Forest in Germany.
