Parker Presents Midigas Nitrogen Generator

The Industrial Division of Parker Hannifin will exhibit its latest nitrogen-gas generator for the food sector at the Gulfood exhibition in Dubai, from 21-24 February 2010. Industrial nitrogen-gas generators are an alternative to traditional bottled or bulk storage nitrogen sources in applications such as modified atmosphere packaging, purging, blanketing and pressure transfer.

A fully operational Midigas nitrogen generator will be on display at the show and Parker will demonstrate how food-grade nitrogen can be produced from a standard compressed-air supply, safely and cost effectively. The Midigas range, in addition to the Maxigas nitrogen-gas generation models, have been developed as compact, stand-alone units that allow food processing and packaging companies to produce their own supply of nitrogen in-situ and on demand. The generators are said to be capable of producing an immediate supply of high-purity nitrogen safely and reliably.

The Midigas and Maxigas generators require power and compressed-air connections to install. They are modular in design so that each system can be extended as and when nitrogen requirements increase. The systems use pressure swing adsorption technology, with pairs of extruded aluminium modular columns filled with high-performance carbon molecular sieves to adsorb oxygen from a compressed-air supply. The larger nitrogen molecules pass through each sieve to a storage vessel, from where the nitrogen can be supplied at carefully controlled pressures as a carrier, make-up or purge gas.

The generators are part of a wide range of separation and filtration systems available from the Industrial Division of Parker Hannifin. They are backed by a worldwide network of manufacturing, sales and technical support centres.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
