Rosenberg has recently expanded its high-efficiency E-Series backward-curved impellers to now include sizes from 12.4 to 22 inches with either AC or EC motors. The unique airfoil blade impeller increases energy efficiency by up to 4% and reduces noise by 3 to 5 dB(A). Recommended for computer room air conditioning and air handling (CRAC/CRAH), or energy recovery. … [Read more...]
New Cooling Fan Blade Design
Cradle has released their new simpler, faster solution for fan design, SmartBlades. SmartBlades simplifies axial cooling fan design by automating generation of blade geometry CAD data. Engineers adjust parameters for blade number, profile, and twist. Shape information can be output in Parasolid XT format compatible with most CAE software. Or seamlessly import it into Cradle … [Read more...]
New PWM Controller for Fans Released
SANYO DENKI has recently released their “San Ace PWM controller”, which controls fan speed through PWM. This contributes to reduced system power consumption and the fan noise. Up to four PWM-input fans can be connected to each controller, without requiring a costly function generator. The controller can be powered by the fan power supply at rated voltages of 12, 24, and 48 … [Read more...]
New Speed Controllers for Fans to Reduce Energy Consumption
Orion Fans has recently developed a low-cost dual channel phase control unit to control fan speed for single or multiple fan assemblies, series OA11/22. It is field adjustable, with the ability to precisely control fan noise, speed, and air delivery according to application requirements. It also comes with four factory presets that allow for maximum flexibility with minimum … [Read more...]
Thermoelectric Modules That Achieve Higher Heat Flux Densities For Cooling Industrial Lasers
Laird has recently developed a high heat flux density thermoelectric module (TEM) designed to achieve a higher heat pumping capacity than standard TEMs, called UltraTEC. “The UltraTEC Series TEM has a heat pumping capacity up to 340 watts, which is ideal for larger cooling applications with limited surface area such as industrial lasers,” claimed Laird. It also has a “precise … [Read more...]
