Orelis’ Pleiade® MP4 filtration module is star performer

Orelis of France is launching a new individual filtration module, the Pleiade® MP4, for the ultrafiltration of electrophoretic paint. The competitively priced module is available in two versions – MP450 and MP470 – and is easy to use and clean (both plates and frame), while offering the compactness of spiral modules.

Based on the tried and tested Pleiade® technology, the filtering surface of the Pleiade® MP4 is a stack of separate membranes. A unique feature is that users can see the quality of permeate from each membrane through a window and isolate individual membranes by means of a small valve. This means that there is never any production stoppage. The MP4 module is designed as an alternative and replacement to spiral systems and retains the modular concept offering flexibility and ease of maintenance. The module can be put immediately into service as new or replacement equipment.

The MP4’s major components are manufactured from plastics and composites. The MP4 is strong and extremely resistant to any type of corrosion and its design makes it interchangeable and modular. The price is competitive and provides a rapid return on investment. It is light and compact (weighing less than 100kg), and is very easy to handle. The membranes are supported on flat plates with an open paint channel, which offers more stable performance and more effective membrane cleaning. The surfaces are fast and easy to clean with the permeate. This ’green’ module does not emit polluting effluent.

Orelis filtration modules have many applications in the field of surface treatment. In the automotive and mechanical engineering sectors, systems produce the ultrafiltrate needed for rinsing after cataphoretic painting, and recycle demineralised water. They also separate water from oil or recycle degreasing baths. To date, Orelis has supplied all the major automotive manufacturers and more than 100 of its modules are in operation across the world.

Orelis also offers different types of membranes suitable for new types of paint. These new membranes can be used to enhance the filtrate or concentrate in widely diverse applications. Orelis’ expertise covers a wide range of membranes, and includes advice for use and implementation. Orelis also offers a complete range of services, from audits to operator training.
