Regal Beloit Corp. says it has developed its most energy-efficient motor in NEMA Premium® frame sizes. According to officials, the NovaMAX motors are ultra-efficient, electronically commutated permanent magnet motors. NovaMAX motors are packaged in standard NEMA frame sizes and mounting dimensions enabling simple substitution in retrofit applications. Available in frame sizes from 48 to 280, the NovaMAX motors are compatible with readily available VFDs from most leading manufacturers.
Creating a better indoor environment sometimes takes a revolutionary step and a new way of thinking. The HVACR industry shows no signs of resting on its laurels as the need for greater energy efficiency, IAQ, and sustainability continues to grow. Engineered Systems asked some the winners of the AHR Expo Innovation Awards winners about current trends and what the future of technology looks like.
Schaffner has expanded its line of dv/dt filters to include the FN5060HV which protects AC motors up to 690/600VAC from destructive effects of peak voltages and inrush amps. This patented technology protects motors and adjacent equipment without capacitors or resistor. They efficiently reduce high output dv/dt from IGBT motor drives and eliminate over-voltages caused by line reflections on motor cables, per IEC 60034-17/25. Typical dv/dt reduction is a factor of 8 to 12.
This second look at the Museum Of The Bible project focuses on the integrated life safety design approach. The team arrived at a final design that not only provides functionality appropriately tailored to the space but also incorporates itself into architectural elements to preserve aesthetic value. The BAS plays a key role between the mechanical and electrical sides of smoke control as well.
The Museum of the Bible (MOTB) will be a non-sectarian museum focusing on the history and impact of the Bible with a core collection of more than 40,000 biblical antiquities and rare biblical texts and artifacts.
It might seem like an odd objective, but the potential efficiency gains are real. And from heat recovery chillers to modified humidification targets so are the opportunities to replace steam production with hot water generation and to manage remaining steam needs more intelligently.
The production of thermal power is critically important in carrying out the mission of health care facilities where it is used for space heating, humidification, domestic water heating, and for processes in dietary, laundry, and sterilization departments.
Engineered Systems magazine’s March 2020 issue showcases how students at one Apple Valley, Minnesota, high school helped the facility achieve LEED Gold; how engineers can design a system to heat a building using a chilled water system, the codes and steps behind adequately design a K-12 safety shelter, and much more.
