Reverse Flow Filtration Systems Intelligent microfine filtration

Reverse Flow Filtration Plants FRANKEN Reverse Flow Filtration Systems: a perfect combination of filter technology and expertise in plant engineering and construction. Our RF reverse flow filters are engineered to meet the demand for state-of-the-art liquid superfilters. Reverse flow filtration system RFA 600-14000 for roll texturing machine Users benefit from these advantages: • Superfiltering with no need for filter aid • Fully automatic/operator-free operation • Low running costs • Low maintenance costs • Guaranteed service life for filter elements This filter technology, fully able to...

The supply of connected machines Customer-specific supply stations for connected machines or rolling mills often form an integral part of reverse flow filtration plants. We are able to supply • Clean and dirty tanks to your requirements, including mutiple tanks • Pumping stations with all fittings, pipes, measurement and control devices • Heating and cooling systems Milling oil storage tank with pumps, heating, cooler, adsorption filter System Control Fully-automatic SPC systems with user-friendly help programs which provide operating mode and malfunction monitoring displays are standard....

Technology Process limit values: Viscosity Solids Temperature RF filter elements easy-to-install reliably sealed ( O ring ) Our reverse flow filter technology is based on a modified gap filter principle: extremely thin filter disks are stacked on a perforated central pipe and pressed down at a defined force. The degree of filtering depends on the width of gap between the filter disks. Modification of average filter gap width (and thus the fineness of filtration) can be achieved by applying filter disks of various surface roughness and modifying the pre-pressure. Filter disk materials:...

Reverse flow The process is engineered to ensure that the filtering effect is 100% with each new start of the filtering cycle. Filtration Pre-draining Reverse Flow Clean Tank Dirty Tank Application example: Filtration of rolling oil Rolled material Copper, copper alloys Filter output 3500 l/min Viscosity of rolling oil 8.5 cSt ( 40°C) Fineness of filtration 1 µm Filter area 2 x 66m2 Residual contaminant < 20 mg/l AN < 0.1 after 5 years The filtrate which compressed air forces through the filter elements during reverse flow is stored in the head of the filter housing. Advantages: • defined...

Reverse Flow Filters and Driers Reverse flow filters Filter elements This filtering technology, and in particular the uniquely engineered reverse flow, are key in the realization of filter areas (even if extensive) within a single housing at no sacrifice in terms of efficiency. We are therefore in a position to supply reverse flow filtration plants of very high throughput. Our filter elements are built to engineering principles according to which mechanical failure, even after use over periods of many years, can be more or less excluded. This is why we are able to offer a long-term warranty...

Driers The design of our range of vacuum driers follows on from our RF filter engineering: • fully automatic • no filter aid required • self-monitoring • low maintenance costs while integrating all components necessary to the process. The multiple safety design of the driers satisfies the highest requirements. Reverse Flow Drier FTA 1000-B Chain drive + reversing cylinder Spray lance with cleaning nozzles Drying process Container Filtered Liquid Special waste tank SAP 450 as integral drier component and with monitored park position Driers need to be able to completely separate all solids...
