Gast Launches Jun-Air Modular Dryer Range

Gast has launched a new Jun-Air range of high-purity, heatless desiccant air dryers featuring a system that combines the filter and desiccant in one easily exchanged, externally fitted cartridge. The IQdryer's design incorporates patented technologies and modern materials to deliver pulse-free, high-quality compressed air with increased reliability, lower running costs and simplified maintenance procedures. The dryer also meets high standards of purity and delivers air in accordance with ISO 8573:1-2001, Class 2 dirt (1 micron) and Class 2 water (-40C pressure dew point).

It has a maximum working pressure of 12 barg. It features: high-tensile extruded aluminium columns containing twin dryer chambers anodised for corrosion protection; a pressure-maintaining device that ensures desiccant bed velocities are controlled to maintain dew-point performance; and two filter/desiccant cartridges (one per column) containing desiccant and inlet/outlet filtration.

The chamber design also ensures that replacement filter/desiccant cartridges can only be fitted in one direction to eliminate installation errors in the field. Other features that are said to ensure optimum reliability include the collection of condensate in a 'quiet zone' that is then vented frequently by timed solenoid valves to eliminate the risk of float-drain malfunction; and purge adjustment screws located after fine dust filtration to eliminate contamination and loss of performance.

An all-in-one service kit is also available with full instructions, and replacement cartridges sealed in airtight foil bags to prolong shelf life. The IQdryer is available on all Jun-Air cabinet compressors with immediate effect, and will be rolled out to the company's open compressor models - including the oil-less OF300 and OF1200 series - from September 2010.

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.
