New Axial Fans - Compact and High-Performance for Commercial Vehicle Air-Conditioning

ebm-papst, the leading manufacturer of motors and fans, is again represented with innovative fan solutions for commercial vehicle air-conditioning at the 2011 APTA show in New Orleans, LA.

New GreenTech EC axial fan for commercial vehicle air-conditioning.

One highlight that ebm-papst will be presenting to the public is a new generation of powerful axial fans in a flat design.
ebm-papst's GreenTech EC technology allows the new fans to work extremely efficiently. The integrated electronics make precise and thus efficient control of the air-conditioning system possible. The user benefits from already familiar linear voltage and pulse width modulation control, and also from an optional new LIN bus control. The electronics are encapsulated in accordance with protection rating IP 6K9K and fulfill all requirements for harsh ambient temperatures such as heat, dust and extreme weather fluctuations.

The flat, compact design and the new, seven-blade fan impeller significantly improve the aerodynamic characteristics in commercial vehicle air-conditioning systems. This guarantees quiet and efficient operation.
The use of fiberglass-reinforced high-performance plastics provides for good mechanical stability of the fans and at the same time for reduced weight. This enables the vehicle payload to be increased and fuel consumption to be reduced even further.
On applications that are exposed to high ambient temperatures, the new power-derating system adjusts the power input of the fan to ensure that reliable fan operation remains guaranteed at all times. A thermal shut-down of the fan and the resulting malfunction of the air-conditioning system are thus things of the past.

Of course, the new fans are already approved in accordance with the new EMC directive ECE-R 10.

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.
