Over the past year, the U.S. Department of Energy (DOE) has issued more than a dozen final rules that directly or indirectly impact the HVACR industry. Two, in particular, directly regulate minimum efficiency requirements for HVAC motors.
The EX3 is a stepper-motor-driven electronic expansion valve (EXV) that provides precise mass flow control and high energy efficiency for supermarket showcases and cold rooms with multiple parallel evaporators.
With constant voltage (CV) and constant current (CC) modes, the 9111 DC power supply automatically recalculates voltage and current limits for each setting to deliver any combination of its 60-V/8-A output range within 180 W.
The Vacon 100 Flow is an ac drive specifically designed to improve flow control for multi-pump applications in which several pumps are used in place of a single one.
This power-dense motor and power-matched adjustable-speed drive replaces the right-angle gearbox and jack shaft installation found in many conventional industrial process cooling towers.
