| 02/08 Compressed Air Industry BULK HANDLING | RESOURCES FOR ENERGY ENGINEERS PRODUCT PICKS Performance-Certified Rotary Screw Air Compressors Available in flows from 424–1024 cfm and pressures to 217 psig, the new DSD series compressors are part of the new CAGI Certified Performance Verification Program. Feature optimized Sigma Profile airend, patentpending Sigma Control system and the latest one-to-one direct drive technology. DSD units are true direct drive compressors with an oversized airend connected directly to the motor via a maintenance-free coupling for maximum efficiency. Remote grease fittings for the drive and fan motor also increase bearing life. A unique cooling airflow design significantly reduces noise levels and provides superior cooling. Plus, all units are fitted with a re-designed, high-efficiency separator system for extremely low oil-carry over. Gas Detection Instrument High-Capacity Inverters The SJ700 extends Hitachi’s model range up to 500 hp, and significantly expands on the performance, capabilities and functions of the SJ300. Three models — 250 hp, 400 hp and 500 hp — are being released at this time. The SJ300 remains to cover the range from 200 hp and below. An improved Sensorless Vector (SLV) control algorithm enables the SJ700 to develop more than 150% starting GfG’s new intrinsically safe G460 is a rugged, compact instrument for simultaneous detection of up to 6 gases. Installed sensor options include infrared (NDIR) for CO2 and PID for VOC measurements. The G460 offers completely automatic calibration, one-button operation, top mounted display and interchangeable battery packs. GfG’s concussion-proof boot, along with the highly dust and water-resistant housing protect the instrument in the harshest environments. Data logging and event logging are standard.
