GE cartridge filters for extreme duties
Technology news
Filtration+Separation July/August 2011
GE cartridge filters for extreme duties GE has developed a new range of depth cartridge filters for use in extreme filtering applications, including hot water sanitising, high-temperature process chemical streams, high-viscosity fluids, highpurity environments and very dirty streams where significant pressure drops can develop. The company says that the ZCore range is available in a variety of micron ratings and lengths and can filter particles as small as 0.5 μm. The filters meet the criteria for use in USP Class VI environments and function at maximum pressure differentials ranging from 1.03 bar (15 psid) at 82°C
(180°F) to 4.14 bar (60 psid) at 30°C (86°F). ZCore filters are manufactured with GE’s patented Z.Plex meltblown, graded-density, filter technology, which feature small-diameter fibres and a three-dimensional fibre matrix design. The technology enables higher particle-removal efficiency and particle-holding capacity in high-pressure environments compared to other depth filters with similar removal efficiencies, the company says. The filters also have an injected moulded polypropylene support core for improved strength and temperature resistance. They have an all-
polypropylene construction which is resistant to chemical and thermal degradation and provides no contamination. “The graded density of the new ZCore depth filters allows larger particles to be trapped near the filter surface, while smaller particles penetrate deeper and are trapped nearer the centre of the filter. So-called depth filters without this graded-density feature really operate only as surface filters in practice,” said Bill Laidlaw, global product manager, filters and membranes for GE Power & Water. “GE’s […] manufacturing process continuously extrudes and thermally bonds pure polypropylene microfibres into a complex gradeddensity filter matrix.” The depth filters are suitable for applications such as food and beverage, chemical processing, hydrocarbon processing, microelectronics, industrial manufacturing, power generation and wastewater remediation. All GE cartridge filters are made without wetting agents, solvents, anti-static agents or binders and are FDA-compliant for food and beverage contact.

FRS available at entry level Fuel purifier manufacturer RCI Technologies now offers an entry-level line of its automatic fuel recirculating systems (FRS). The entry-level model is priced lower than the regular units, and has no touch screen or internal enclosures for the wiring inside the cabinet. The PLC controls the alarms only and power upgrades are the only option available.
The entry-level system is similar to other FRS units in that it cleans and circulates the customer’s stored fuel on a pre-programmed schedule, is PLC-controlled, has a key switch and a 24-hour, sevenday programmable clock, is UL-listed, and is housed in a NEMA 4 key-lockable cabinet. “The entry-level system enables customers working with a more limited budget
to also benefit from RCI’s patented fuel purification technology, but at a lower cost and with a simpler interface,” RCI President Robert Randle said. The EL series is available in three flow rates: 5 gpm (FRS 660-5-EL-UL), 11 gpm (FRS 660-11-EL-UL) and 25 gpm (FRS 660-25-EL-UL).
