EDITOR’S CHOICE Eco-Friendly Eco-Mag Cuts Filtration Costs, Reduces Environmental Impact is that a system based on a magnetic cooling cycle can be relatively small. Such systems are ideal for a variety of applications ranging from the cooling of electronic components to refrigerators and air conditioners.” As this technology does not use gaseous refrigerants, it is quieter and causes fewer vibrations than conventional compressor type refrigerators. Magnetic Products, Inc. (MPI), a provider of both magnetic and non-magnetic material handling solutions, has introduced the Eco-Mag. The Eco-Mag is a highintensity magnetic filter that improves filtration efficiency over conventional systems. It uses high-power neodymium Rare Earth magnets to remove ferrous and para-magnetic contamination from fluids and is particularly effective with machine tool oils, coolants and hydraulic fluid machinery systems. The environmentally friendly Eco-Mag does not use filter consumables. Furthermore, removed contamination can be recycled, eliminating disposal costs. The high filtration efficiency provided by the Eco-Mag means lubricants and coolants last longer. Any industry that uses fluids can benefit from installation of the Eco-Mag filter system. Flat Wire Inductors Excel at High Temperatures New Magnetic Materials for Efficient Cooling The Foundation for Fundamental Research on Matter (FOM) in the Netherlands and BASF will start another joint research program on magnetocaloric materials. This new class of materials may help to make today's cooling systems more efficient and quieter. This is the second joint research project between FOM and BASF and it has a duration of four years. “We aim to achieve an even better understanding of the fundamental magnetocaloric principles, which will help us to develop new materials with improved properties and we will investigate the best routes for large-scale production,” said program leader Prof. Dr. Ekkes Brück (Delft University of Technology). FOM and BASF started their cooperation in 2008. The previous research program yielded new insights into the physics underlying the giant magnetocaloric effect. Together with their industrial partners the researchers are working on the market introduction of the first devices based on magnetocaloric materials. Magnetocaloric materials heat up in a magnetic field and cool down again when they are removed from it. A heat pump based on magnetocaloric materials may therefore be an alternative for traditional cooling cycles. Cooling systems based on the magnetocaloric effect could significantly reduce energy consumption. “Theoretical considerations reveal an energy savings potential of up to fifty percent,” said Dr. Thomas Weber, managing director of BASF Future Business GmbH. “An added benefit Featuring a flat wire design that is coiled and mounted directly to the circuit board to allow efficient heat dissipation, the new DR79892 and DR79893 Flat Wire inductors from Datatronic Distribution, Inc., are designed for performance in power supplies, industrial controls and instrumentation applications. Flat wire inductors are well suited for power supply applications where high temperatures often effect performance. Their compact flat wire design provides for better thermal management, which results in improved performance and reliability. The DR79892 and DR79893 inductors are insulated to a minimum of 100M Ohm at 500 VDC between coil and core. Rated to Insulation Class E, they are operable to a high temperature of 120°C. These design characteristics make them useful for equipment produced for use in heavy-duty commercial orrugged industrial environments. The Model DR79892 Flat Wire inductor features an inductance of 4.0 µH and a rated inductance of 2.5 µH. It offers a 45 A rated current, a 0.8 m Ohm maximum DC resistance and 500 Vac isolation between coil and core. These inductors are sized at 0.63 inch (16 mm) width by 1.14 inch (29 mm) length by 1.16 inch (29.5 mm) seated height. The Model DR79893 Flat Wire inductor features an inductance of 45 µH and a rated inductance of 40 µH. It offers a 30 A rated current, a 4.0 Ohm maximum DC resistance and 500 VAC isolation between coil and core These inductors are sized at 1.14 inch (29 mm) width by 1.69 inch (43 mm) length by 1.97 inch (50 mm) seated height. In 10,000 piece quantity, the Datatronic DR79892 Flat Wire inductor is available beginning at $3.50 each, and the DR79893 Flat Wire Inductor in 10,000 piece quantity is available beginning at $7.60 each. Lead-time is stock to six weeks. Volume OEM pricing is available upon request. 4 Magnetics Business & Technology • Fall 2011 www.MagneticsMagazine.com http://www.MagneticsMagazine.com
