Ellison’s PowerNow power operated doors use a concealed low energy operator and actuating arm to effortlessly provide the opening force, while Ellison's standard hardware provides the closing force. PowerNow-equipped doors, when operated manually, do not interface with the powered mechanism in any way, which minimizes energy use and guarantees that the user-experience is still pure Ellison. This design reduces energy costs, eliminates unsightly surface mounted hardware, and limits wear on the power-operated device.
