iSpeed Drives Match System Output To Demand

Parker Hannifin has launched a range of intelligent variable speed drives that it says will deliver energy savings for users of commercial and industrial refrigeration and air-conditioning systems. The company said the drives can cut up to 40 per cent of the energy used by refrigeration systems with single compressor units and up to 25 per cent from the energy consumed by conventional multi-stage compressor racks.

The drives, designated iSpeed, are designed to control the operating speeds of compressors, fans and pumps, matching system output precisely to variations in demand, giving optimum energy efficiency with low maintenance and long-term reliability. In addition, the ability to ensure accurate control of refrigeration systems, with precise and smooth adjustments in compressor speed to match operating load demands, helps to minimise the problems caused by fluctuations in pressure and temperature.

In the example of food refrigeration, this preserves product integrity and improves shelf life by reducing dehydration and shrinkage. Similarly, by controlling the cycle rates of compressors, with a smooth increase and decrease in compressor speed, the iSpeed drives reduce wear and stresses on moving parts. The same technology also enables fewer compressors to be used in many applications, with one variable speed controlled compressor being temporarily run at higher capacity, rather than starting several fixed speed compressors to meet short-term increases in load demand.

In a typical installation, a single iSpeed drive can control one variable speed compressor and up to eight fixed speed compressor units. The drives can be retrofitted by end users to existing refrigeration or air-conditioning systems, or used by OEMs in new builds. In each case, iSpeed drives are easy to install, configure and operate, featuring pre-programmed modular control algorithms and interfaces to a range of standard third-party controllers. The iSpeed family of intelligent variable speed drives has been developed through a partnership between Parker Hannifin's Sporlan Valve Division and KIMO RHVAC.

Han® HC 250 high current contact

A Powerful Solution HARTING has developed the new Han® HC 250high current connector as a powerful interface that impresses by requiring little space, transmitting high current intensities and allowing flexible configuration of the number of poles. The HC 250 one-pole crimp module can be connected in various frame geometries to produce the required number of poles in a compact space – and in the existing Han® HPR housing. Technical details: - Rated current 250 A at a rated voltage of 2000 V - Termination cross-sections are: 35 mm2, 50 mm2 and 70 mm2 - Maximum four-pole interfaces in a size 24 B HPR housing, making it particularly suitable for motor connections - High quality plastic with good smoke and inflammability levels - Removal tool for simple installation and removal of the contacts and inserts - Confusion of a number of interfaces is reliably prevented by multiple coding options for the individual inserts The requirements in the railway industry are changing, as

EGCS-D0 Accelerometer Now Available in 10,000g Range

Measurement Specialties, Inc. (NASDAQ: MEAS) has recently redesigned the EGCS-D0 accelerometer to enable it to accurately and reliably measure up to ±10,000g. This rugged device is critically damped, which is the ideal mechanism to protect the accelerometer against ±20,000g impacts and prevent sensor ringing. The EGCS-D0 accelerometer is now available in ranges from ±5g to ±10,000g which makes it ideal for both critical low-g measurements and high-g impacts. These units feature a Wheatstone Bridge mV output with a standard compensated temperature range of 20ºC to 80ºC (other options available). The EGCS-D0 was specifically designed for impact and shock testing in auto safety, aerospace, military and civil engineering applications. Designed to be bolt-mounted, this device operates from 2-15Vdc excitation with electrical output ratiometric to voltage input. Optional triaxial mounting blocks (MTG-F4), signal conditioners (Model 101) and auto-zero inline amplifiers (Model 140) are avai

Ilix Cermet Reamers Are Ideal For Dry Machining Engineers Cutting Tools, the UK agent for Ilix, has introduced Ilix solid-carbide and cermet reamers for the machining of hard metals. The machine reamers 6372C and 6323 allow the production of high-precision holes with good surface finish. Compared with HSS, the solid-carbide qualities enable the increase of cutting parameters and tool life. The quality of the reamers is said to guarantee high performance, even for hard metals with a resistance more than 1200N/mm2. The Ilix carbide 6372C range of hundredth reamers is from 0.98mm through to 12.05mm in increments of 0.01mm. The reamers are manufactured to a tolerance of +0.000 - +0.004mm. The cermet reamers 6323 have new cutting geometry developed by Ilix. These reamers are said to be ideal for steel machining, having high chemical stability during the cutting process. They offer good wear resistance due to the high hardness and have low material adhesion. The Ilix cermet reamer is said to
