Bosch Rexroth expands into filtration market

Collaboration aids safe drinking water solutionsBosch Rexroth has expanded

its product portfolio in the UK market to include its own range of filtration systems.

The range expansion is the result of Bosch Rexroth’s acquisition of K & H Eppensteiner GmbH & Co in 2009, one of Europe’s most established filter manufacturers.

Dow Water & Process Solutions (DW&PS) has entered into a collaboration agreement with Ahlstrom to use Ahlstrom Disruptor® technology for drinking water applications.

The company says that the agreement combines DW&PS industry-leading market, R&D, and manufacturing expertise with Ahlstrom’s nonwoven fibre technology to address an unmet need in drinking water applications.

According to the United Nations, nearly one billion of the Earth’s seven billion-plus people do not have access to clean water and our world’s population is expected to grow by another 3 billion people within the next 40 years. In order to keep up with rising populations, affluence and demand, the World Business Council for Sustainable Development (WBCSD) estimates that our world will need 30 percent more water. Consequently, the United Nations has designated 2013 as the International Year of Water Cooperation.

DW&PS will incorporate Ahlstrom’s high-performance, filter medium into a new set of drinking water purification products that offer excellent pathogen rejection while operating at high flow and low pressure. The main benefits are:• Health and safety: Virtual removes microorganisms that can cause sickness by removing 99.9999% of all bacteria, 99.99% of all viruses and 99.9% of all cysts in a water stream.• High performance: Operation at a high flow rate even at low pressure for drinking water applications. • Sustainable: Suitable for use in areas with no electricity, requires zero chemicals, and does not generate wastewater.

Mott introduces sterilising grade all-metal filtration membraneMott Corporation has developed an all-metal sterilising grade membrane for medical filtration applications. The membrane is produced using nano-materials and a proprietary manufacturing process developed by Mott. The membrane meets or exceeds a 0.2 μm filtration challenge and meets ASTM F838-05 for bacterial retention. Mott says that this material is ideally suited for applications in medical, life sciences, biotechnology and pharmaceutical industries and can be used in implantable devices as well as for filtration of liquids or gases in which cleanliness and removal of bacteria is critical. It is also being used in various industry developments within aerospace and new energy research.

The filter is intended for circumstances requiring ultra-fine,

sub-micron filtration. It is made of stainless steel or titanium and is capable of achieving extremely efficient levels of filtration and separation (> 7 LRV @ 0.2 micron).

Mott adds that its sterilising grade filters offer a solution for industry devices that require a stronger, more durable and longer lasting product. It is biocompatible, impervious to solvents, and compatible with most organic compounds and complex drug chemistries.

Mott’s sintered porous metal products are currently being integrated in various implantable devices, as filters to prevent plugging of catheters, in drug delivery devices, in medical

instrumentation, as bacteria filters, as sparging devices for cell culture processing, and as gas flow restrictor devices for gas delivery in life-critical systems. It has also been used to filter carrier gases and cryogenic fluids, as well as site markers used in the human body. Potential uses are countless and diverse.

Each application has unique requirements and is reviewed by a specialist team of engineering and technical experts. In addition, Mott’s porous metal products can be autoclaved, sterilised or completely recycled; an important attribute for maintaining cleanliness standards as well as conservation of resources, energy and space.

The Eppensteiner range of filtration products is now being rebranded Bosch Rexroth.

As a result, the Eppensteiner range of filtration products is now being rebranded Bosch Rexroth and being made available in the UK.

The breadth of the range covers all aspects of filtration with high flow rates and several pressure ranges in return and pressure types

such as inline, manifold, tank mounted, duplex and all with indication options. They can be applied to a range of applications, from agriculture through to rail, mobile and industrial. The new product portfolio also contains all filter accessories, including filter programs, oil purification, measuring instruments and specific condition monitoring systems.

The expanded range will include the LE (N) 0040-0400 series filtration system, which has an innovative filter head design resulting in a ‘cyclone effect’ which diverts the inlet flow in a specific direction which enhances the flow properties and dirt absorption capacity. In addition, the filter also boasts a newly designed bowl which improves element mounting and stability which keeps the element in place ensuring constant pressure distribution.
