Heat Transfer Products Group (HTPG) released its new Next-Gen All-Temp Low Profile Unit Cooler line. The new design features high-efficiency motors, new fan guard design and deep draw venturi to achieve optimal air flow, coils with enhanced copper tubing, and redesigned housing.
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.
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. The age of the hospital, the programs offered, and the regional climate will all affect the demand for thermal power.
