Software Speeds Development of Baby Milk Warmer

Intelligent Fluid Solutions (IFS) has saved more than two years and USD54,000 in development costs for the Yoomi combined baby milk warmer and bottle, using simulation software from Ansys. A bottle and warmer in one, the Yoomi heats a baby's feed to the natural temperature of breast milk at the touch of a button, in just 60 seconds. The cold feed is warmed as it flows through specially designed channels on the outside of the warmer.

By the time the feed reaches the teat, it is at natural breast-milk temperature. Ansys engineering software was used to solve the design challenge of taking fresh milk from 5 to 34C within one minute of activation, across a full range of baby drinking speeds. The engineering team used Ansys CFX to simulate the multiphase fluid dynamics of the proposed design. By evaluating simulated prototypes, IFS doubled the performance of the initial design while building only four physical prototypes.

This saved USD54,000 by avoiding the need for 12 physical prototypes and delivered the Yoomi to market two years earlier than otherwise would have been possible. When development of the Yoomi first began, each prototype cost USD4,500 and took a week to build. In addition, the properties of the rapid prototypes did not match the production version of the bottle warmer. Yoomi's developer estimates it would have taken 16 prototypes over four years to develop a marketable product. Ansys CFX cut this time and cost and gave its development a head start. When the Yoomi was launched on the web, the initial production run sold out in just four days. Production has been increased to meet demand and distribution channels are being expanded to include UK and international retailers.

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.
