Passivent Develops Acoustic Ventilation Solution

Passivent has developed SoundScoop in association with Arup, a product that combines natural ventilation with noise attenuation. It significantly reduces sound transmission from one area to another, while enabling low resistance airflow - essential in naturally ventilated buildings.

This can help reduction in energy consumption as part of the continuing drive for zero carbon buildings, without compromising acoustic performance targets as described in British Standards and Building Bulletins. SoundScoop is positioned at high level in the partition/wall between two internal spaces, enabling natural air movement with minimal pressure drop. A patented sound absorbing lining optimises attenuation of mid frequency sound, typically the most problematic.

Accredited laboratory testing has demonstrated that an acoustic performance of up to Dnew44 can be realised. SoundScoop's design of an ABS sleeve with foam lining enables it to be flat-packed for easy transportation, with 16 product models available to suit most situations. The smallest 300x300x300mm unit with standard acoustic foam provides Dnew31, and an average attenuation of 34dB at mid frequencies. The largest 600x300x1,200mm with high specification acoustic foam provides Dnew42 and an average attenuation of 51dB at mid frequencies..

Further enhancing its green credentials, SoundScoop is manufactured from 100 per cent recycled ABS and recycled foam. Passivent is the UK's leading designer and supplier of natural ventilation systems for both domestic and commercial applications. The company has contributed to the BSRIA guide BG2/2005 Wind Driven Natural Ventilation Systems, as well as being a member of the DSCF steering committee on ventilation guidance for schools, Building Bulletin 101.

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.
