Upgraded performance and lower maintenance
The PrimeFilter D builds on ANDRITZ disc filter technology, that has been proven over decades, and brings together several key technological innovations into one unit to improve throughput and reduce both investment and operating costs:
- HHw technology for advanced feeding and optimum flow conditions within the filter. Thus, the PrimeFilter D can handle higher feed consistencies and higher freeness pulp even in most demanding applications.
- CC bagless sectors offering significant improvements in terms of operation thanks to very homogenous fiber mat build-up as well as fast mat knock-off. The special construction of the sectors eliminates the need of a filter bag and reduces maintenance to almost zero.
- Two-level shaft sealing. The innovative double sealing arrangement is easily accessible and ensures higher reliability at superior filtrate quality.
