Air Vacuum Removes Flammable Chemicals

Huntsman Advanced Materials has utilised a Nilfisk CFM air vacuum cleaner to safely collect and dispose of highly flammable residue, water and toluene. As well as producing Araldite adhesives, Huntsman also manufactures and markets a wide range of differentiated chemicals to automotive, coatings, construction, aerospace, electronics and wind energy sectors. The site is strictly regulated by the Environment Agency and regularly audited for Comah compliance. Standards in place include ISO14001, OHSAS 18001 and aerospace certification EN 9100.

Huntsman recently had two production issues that needed an improved resolution. Highly flammable resin residue, water and toluene needed to be safely collected and disposed of. Flame permits had previously been necessary until Nilfisk CFM provided the A17 DAU (absolute filtration) air vacuum cleaner. The industrial machine is completely air driven, therefore intrinsically safe and rated for Atex Zones 1 and 2 as well as dust zones 21 and 22.

The body of the unit is manufactured from 316 grade stainless steel and was supplied with a mechanical float system and drain plug. After collection, waste products are wetted out with water and sent to an in-house effluent plant for contaminated waste treatment. Fine chemical powders rising to and settling on high level overhead pipe work was also a risk factor. To combat this risk, Nilfisk CFM supplied an integrated 2m extension tube with specialist pipe brushes attached. This enables Huntsman staff to stay safely at ground level at all times during the cleaning process.

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.
