The SPRAY project will demonstrate the feasibility of a new system based on an innovative water inlet, which allows to directly spray fresh water into the center of the laundry.

A second water path, as today conventional washer have, still provides a means to enter the detergent into the wash process conventionally, thus maintaining the same washing performances.

Compared with the best technologies present on the market, the SPRAY solution will be unique in keeping the same customer satisfaction on wash and rinse performances, while reducing at the same time the water consumption significantly, as well as energy. For a typical household, this will result in such an annual water reduction per year, a potential water saving of approx 400 Mln m3 in EU can be expected.

The Overall Objectives of the project are:

  • To demonstrate to the market the technical and economical feasibility of the application of the SPRAY technology for a consistent water reduction in household appliances;
  • To confirm and set up the best production process for the solution proposed, in terms of performances, energy consumption, resources utilization, environmental impacts;
  • To ensure the most effective introduction of the innovative SPRAY solution into the target markets, through the development of a complete business plan, exploitation and dissemination activity.
