Mechanically Cleaned Filter Systems

Ronnigen-Petter mechanically cleaned filters are based on a simple concept: A cylindrical stainless steel housing contains a filter screen; unfiltered liquids enter the inlet; solids are deposited on the interior surface of the filtration media; and filtered fluid exits at the outlet.

When the media requires cleaning (based on time, pressure differential or manual selection) a cleaning disc travels down and up the screen removing concentrated solids. This cleaning process happens while the filter remains in service, thereby maintaining process efficiency and dramatically reducing loss of valuable product.

Designed to address the challenges of increasing environmental pressures, loss of valuable product and operator safety, the DCF is like no other filtration system.

Ronnigen-Petter DCF filter systems are offered in thousands of configurations to help meet a wide range of applications requiring filtration from 15 microns to 6,360 microns for liquids up to 1,000,000 centipose.

Twin Series

Designed for the rigours of processing highly viscous, abrasive, sticky or otherwise hard-to-process liquids, the Twin is ideal for a broad spectrum of challenging applications. To handle highly viscous or abrasive liquids the Twin Series isolates the actuation mechanism from the filtrate with a bridged actuation system. The benefit is a long operating life in challenging conditions. Various types of cartridge seals, along with an optional FluidSeal, keep the integrity of the seal. Systems are available in 800 and 1600 sizes to accommodate a wide range of flow and retention requirements to fit your applications.

Standard Series

When processing water and water-like liquids where a low initial investment is demanded, the Standard Series delivers tremendous benefits with its simple and reliable operation. Standard designs are ideal where a low initial investment is a key driving factor. Various types of cartridge seals, along with an optional FluidSeal, keep the integrity of the seal. Available in 400, 800 and 1600 models, the Standard series enables operation at a vast range of flow rates and retentions.

Media Types

Three media types are available for use in the DCF series - slotted-wedge wire, defined-pore or perforated media.

The slotted wedge wire in DCF filter screens are honed perfectly circular to guarantee contact with the cleaning disc so the slot openings are smallest at the screen's surface. This design helps prevent particle plugging of the slot openings while assuring total rated solids removal.

The tortuous path design of the defined pore media enables elimination of difficult to filter gels. The media is also calendared flat to ensure a uniform defined pore size.

Perforated screens feature precise and uniform perforation patterns for complete removal of larger solids.
