Rittal Identifies and Seals Energy Leaks

On average, IT infrastructure accounts for 50 percent of the energy costs occurring in data centres. Of that, approximately 37 percent is consumed by cooling systems. An optimised climate control system protects the environment and cuts energy costs. Data centre thermal analyses, a new service launched by Rittal, now enable companies to identify and resolve defects in climate control systems.

Rittal is extending its service portfolio. The leading system provider for enclosures, power distribution, climate control and IT infrastructure now also offers thermal analysis services for data centres. The functionality of the hardware and the energy efficiency of IT infrastructures are determined to a large extent by the temperature in the server rack and/or data centre. If the temperature is too high, there is a greater chance that systems will fail and energy costs for cooling increase. Rittal uses thermal analyses to visualise, document and optimise the weaknesses that cause these problems.

The Achilles heel of climate control
In practice, it is not always possible to guarantee that specific temperature thresholds are maintained in server racks. As a result, servers in upper rack areas are often supplied with insufficient cold air and temperatures rise above the specified limit values. Outer enclosures in non-contained cold aisles are often problematic, too, as larger volumes of warm air flow into these areas and mix with the cold air.

Mapping temperature problems
Rittal offers its customers climate analyses that help them check their climate control systems. The analyses involve measuring the temperature of the cold air at the air inlet of each server rack in a vertical pitch of 100 to 200 millimetres and determining the rack surface temperatures using infra-red thermography.

Once the measurements have been processed, customers are given a detailed written report with the measurement results clearly depicted in tables and graphs. This makes it easy to identify temperature problems on server racks and servers. These measurements can then be used as a sound basis for putting in place carefully targeted measures to optimise the climate control system.

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.
