NexRev Inc., a manufacturer of performance-improving energy efficiency upgrades for HVAC equipment, announced that its flagship product, DrivePak™ HVAC Efficiency Upgrade, received a Top Product of the Year Award in the Environmental Leader Product & Project Awards.
The Taco SelfSensing Series with ProBalance™ integrates Taco KV or KS pumps with a variable frequency drive. The pumps allow the installer to accomplish easy do-it-yourself system balancing for both constant flow central plant applications and variable flow building distribution applications.
While variable-frequency drives (VFDs) boast increased energy efficiency as the main benefit, a small — but by no means insignificant — percentage of the drives are causing major problems in the motor they control.
The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) has announced two new certification programs for variable frequency drives (VFDs) and datacom cooling (DCOM) equipment.
U.S. Rep. Adam Kinzinger, congressman for the 16th Congressional District in Illinois, recently visited the Danfoss plant in Loves Park, Ill., within his district.
According to the manufacturer, the variable-speed drive sensorless controller utilizes the latest generation hardware platform with advanced pumping software and proven algorithms to create a smarter, more cost-efficient, and energy-saving pump system for HVAC and pressure-booster applications.
Variable-frequency drives (VFDs), also known as inverters, are widely used because they save energy, especially in applications with variable-torque loads.
All major manufacturers of three-phase ac induction motors offer “inverter-duty” or “inverter-ready” models, but while these motors have inverter-rated insulation to protect the windings, the bearings — their most vulnerable parts — are too often ignored.
Variable-frequency drive (VFD) control panels, the Endura™ line, has been introduced. The Endura PB (Pressure Booster) Control Panel is designed for commercial pressure booster applications using one-to-four VFDs, includes the VFDC-4000 controller and one VFD for each pump.
