Boll filtration systems are the low-maintenance way to remove damaging debris from plastics extrusion cooling water

The Boll & Kirch range of automatic filters and strainers offers the practical, effective solution to cooling water clean-up.

Ideal for cooling systems in the plastics manufacturing industry, Boll Automatic Self-cleaning Filters efficiently remove debris from recirculating water - without the costs of blockages, regular cleaning, downtime and quality issues often associated with manual systems.

Boll filtration systems have been installed in plastic manufacturing sites throughout Europe, including the Veka plant at Sendenhorst in Germany.

Veka is the world’s largest manufacturer of PVC-U products for building and refurbishment, with eleven factories in nine countries across Europe, Asia, America and Russia.

The Veka installation comprises two Boll 6.18 Automatic Filters – Duty & Standby – fitted on the pressurised feed line to the extrusion machines to remove particulates from the cooling water and protect the spray nozzles from blocking.

However, Boll systems can also be fitted on the return line where the pressure can be as low as 0.5 bar. This alternative configuration allows the filters to remove solids after the extrusion machines, protecting the heat exchangers from blockages. The water is then in a clean condition to return to the machines without any fine particles, ensuring a high quality of surface finish on the plastic extrusion.

Trouble-free performance

Manufactured by Boll & Kirch, Bollfilter automatic filters are robustly designed for long-life performance in the most demanding conditions – offering filtration levels from 25 micron to 3mm.

The combination of back-flushing technology, quality engineering and element configuration ensures highly efficient filtration with minimal maintenance requirements.
