Heat Exchangers with Eco-Mode Controls Help Save Electricity

Developments made by Rittal show that even greater energy efficiency potentials are possible with liquid-based cooling systems. The specialist climate control has now trimmed all the components of its current air/water heat exchanger for greater energy efficiency. The new intelligent Eco-Mode controls are now used with Comfort devices that have cooling outputs of 500 W to 5,000 W.
 many cases, simple fan-and-filter units are often not enough to dissipate high heat loads from enclosures. Alongside modern compressor cooling units, which also cool with air, liquid-based cooling systems offer major advantages, depending on the application concerned. Recent developments in heat exchangers show about that a lot has happened in terms of energy efficiency, assembly handling, and availability.

To increase the energy efficiency of the entire cooling system, Rittal has improved its current air/water heat exchangers. New and intelligent Eco Mode controls are now used with Comfort units with cooling outputs of 500 W to 5,000 W. They turn the fan off or on as needed, depending on the temperature in the enclosure. If the internal temperature falls 10° C below the set temperature, the fan switches off. In order to measure the effective internal temperature of the enclosure, the control system switches on the fans for 30 seconds every ten minutes, so ensuring a circulation of air in the enclosure.

The new units also offer assembly benefits: They can be mounted to the enclosure in less than two minutes. The heat exchangers are held in place by simply snap-fitting them to pre-mounted fixtures. Only two screws are needed to fasten the devices securely. Assembly is performed entirely from outside, without the fitter having to fasten the air/water heat exchanger from within.

Rittal has also improved the water connections: Alongside standard connections with flexible hose and plug-in joints and couplings, other types of joint are available such as internal threads, quick-release fasteners, direct hose ports or Ermeto quick-release systems. Such simplifications in handling lead to savings in time during commissioning and operation and cut costs.

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.
