The NEMA/UL Type 4X VLT® HVAC drives deliver reliable operation in environments subject to windblown dust, and rain or splashing water, so they can be installed directly at the equipment location.
Some worry the Ontario Building Code has gone too far and that the legislation may strip consumers of their options while decreasing profit margins for the HVAC contractors installing the equipment.
Variable-frequency drives (VFDs), also known as inverters, are widely used because they save energy, especially in applications with variable-torque loads.
Reducing the locked rotor amperage (LRA) or in-rush current on compressors and motors by 70 percent, the Sure-Start is an electronic, software-driven soft starter that assists in the prevention of brownouts caused by the increased use of equipment during peak periods, said the company.
The Platinum belt by Megadyne is a high-performance rubber-based synchronous belt with duel core hybrid cord technology capable of handling the most demanding drives, said the company.
The modulating linear motors with integrated safety provide varying gas flow control instead of straight on-off control. By incorporating the device into furnaces and other types of gas-burning products, gas flow can be controlled and dispensed in varying amounts so that fuel is burned at a slower or faster rate as needed.
The P-Series line of variable frequency drives (VFDs) has been enhanced with a new redundant VFD unit. The Redundant Drive Panel (RDP) is designed to provide an economical HVAC motor control solution that maintains full control of an application if the primary drive fails.
While shortening the iBLDC™ (Intelligent Brushless DC) motors with integral four-quadrant speed controls in the 45-mm frame size by 25 percent, the new size of motor maintains the same power and torque capabilities and motor efficiencies, said the company.
The Genteq™ Evergreen CM is a universal electrically commutated motor (ECM) for aftermarket light commercial heating and cooling applications. The ultra-high-efficiency ECM features flexible control methods to help the installer balance airflow in HVAC systems such as variable air volume, series boxes, or package heat pumps.
