Efficiency is further enhanced with the use of magnetic bearings, which avoid fire friction of rubbing parts associated with traditional oiled bearings. Conventional bearings can use as much as 10,000 w, while magnetic residentialbrushchippershredder bearings require only 180 w. That amounts to 500 times less friction loss. Current development projects are expanding the range and duty of the compressor wheels and promise to offer even greater efficiency for water-cooled and air-cooled duties and different capacities.CONTROLSThe new residentialbrushchippershredder compressor effectively is a computer. It provides diagnostic and performance information through Modbus to the refrigeration system, which then communicates to the building automation system through Modbus, LonWorks, or BACnet.CHILLER APPLICATIONThe compressor manufacturer and a major chiller manufacturer teamed up to develop a line of ARI-certified water-cooled chillers, which were expected to be introduced in January 2004. The combination of flooded-evaporator technology and an oil-free system has allowed very close approaches and, subsequently, enhanced performance. The integrated VFD allows excellent part-load performance as power consumption drops off, depending on the head relief, near the cube root of the shaft speed.

The backhoe has a powder-coat finish in bright red and yellow. Features include: heavy-duty, self-contained residentialbrushchippershredder frame, residentialbrushchippershredder standard 9 HP Briggs industrial motor, balloon tires, highway-rated residentialbrushchippershredder tires, support residentialbrushchippershredder legs, boom arms, specially shaped bucket for increased digging, replaceable teeth, four-spool control valve, and special hydraulic cylinders. Four models are available, two of which can be towed, residentialbrushchippershredder and two can be attached to three point hitches. Options include a choice of 9 or 12 ft. reach from boom pivot and buckets in a choice of 12 in. width for digging residentialbrushchippershredder or an 8 in. width for trenching. Model BL70 backhoe, with 90-hp. engine, digs to depths of 14 1/2 ft. and lifts 7,619 lbs. Loader bucket holds 1.3 cu. yds. Cab boasts 360 [degrees] visibility. Choose from 2 backhoe control lever configurations. Spring-applied, pressure-released lock secures boom. Store tools, grease guns, and chains in tool box integrated in left steps. Heavy-duty, single-piece chassis tapers at front for 55 [degrees] steering angle. Integral bucket-mounted flipover pallet forks, which residentialbrushchippershredder measure 42 ins.

"Small and mid-sized suppliers have different needs than large enterprise suppliers, and the available electronic resources have typically neglected to offer options appropriate in both cost and ease-of-use. This dearth has created lag time in the supply chain, slowing inventory turnover and increasing overall lost revenue opportunity," said Archie Black, SPS Commerce CEO. "Northern Tool recognizes the possible return-on-investment by creating new electronic residentialbrushchippershredder transaction opportunities for their suppliers through our hosted model. We welcome Northern Tool to our customer roster, and are excited by the chance to provide them with our proven method of vendor enablement and hosted integration services."
