Discover a new dimension in ultrafine filtration with our precoat filter and benefit from innovative technology. As an integral part of our modular system, this system can be seamlessly combined with other systems such as compact filters, sedimentation tanks or endless belts. Optimize your existing system to efficiently handle even the most demanding filtration processes. With our many years of experience and technical expertise, we are at your side to continuously improve your production processes and sustainably reduce your operating costs.
The contaminated process medium enters a dirt tank where it is enriched with a filter aid. Due to defined carrier particles, agglomerates are formed from precoatings and small particles, which have a filterable size. With the aid of a pump, the contaminated medium is allowed to flow into the StingR® drain from below. Relatively large-pored filter elements are used in the unit, where the agglomerates are deposited as filter cake. The cleaned medium reaches the inside of the filter, is discharged there and is either collected in a clean tank or sent directly to the processing machine via a high-pressure line.
The entire StingR® system has an electrical and pneumatic control system. If a filter element is contaminated, this is detected fully automatically by the differential pressure sensor and a backwash of the system is triggered.
The backwashing process takes place via a patented pneumatic-hydraulic system. The dirt is separated from the residual liquid in a separator, leaving behind a filter cake with low residual moisture.
Technical details:
Dry filter cakes and low carry-over of cooling lubricants lead to cost-efficient production, as the service life of the cooling lubricants is extended and production costs are therefore significantly reduced. The formation of a dry filter cake makes it easier to recycle the chips, which has both economic and ecological benefits. With the system, you optimize your use of resources and actively contribute to environmental protection.
The precoat filter guarantees reliable filtration performance and thus ensures even and consistent production processes. Benefit from smooth production without unforeseen downtimes. The increased process stability leads directly to significantly improved machine availability. The extraordinary durability and long service life of the precoat filter guarantee efficient operation over a long period of time.
The precoat filters are characterized by their robust and extremely low-wear design. Thanks to the automatic backwash process, which is triggered by a differential pressure sensor, the filter is cleaned fully automatically and without the need for time-consuming manual intervention. You reduce personnel costs and benefit from extended maintenance intervals and low follow-up costs. The easily accessible filter elements and the maintenance-friendly design of the system simplify service work and save time. This also increases machine availability and productivity.
The reliable and first-class quality of the cooling lubricant, which is filtered through the precoat filter, significantly extends the service life of your tools and processing machines. With our system, you protect your investment and increase capacity utilization. This optimizes the profitability of your tools, as more components are produced per tool.
