Ningbo Ningbo Branch-supply door sensors, automatic door sensors, sensor sliding door, automatic swing features intelligent response to contemporary technology trendy, convenient and user-oriented operation, the overall careful planning, configuration and number of intelligent protection device, automatic doors The control system uses a built-in microcomputer chip can be programmed to automatically set by the control process. Users simply select the desired shutter speed and opening hours, automatic doors that can be sustained to maintain the best condition, degree of intelligence greatly improved. Security has a safety sensing devices, eliminating the hidden folders person, even if someone sliding doors, it will not appear disordered condition of the program, a unique electric lock function, may need to control access to staff, other optional back-up power supply, external power supply so that when the automatic door kept setting off the state to ensure the safety of personnel. Reliability professional mechanical transmission design, specially formulated efficient brushless DC motors, with long life, large torque, low noise characteristics, equipped with advanced toothed belt drive, the door to run more stable and reliable. Environmental protection in order to maintain the overall environment of the resting state of dynamic beam structure gives a new conceptual design, coupled with the use of new materials, will not lead to resonance conduction, so the doors run more light, less noise reduced. Energy efficiency in the door is completely closed, to keep closed state, the air-conditioned environment and the outside world with the Department, allows air circulation is reduced to a minimum, saving heating and cooling costs in summer and winter, to maintain constant temperature and humidity. Purification of the double door interlock, can reduce the amount of indoor clean air to escape and prevent cross-contamination, meet sealing requirements, with good sound insulation. Convenience open sensitive, closed in a timely manner, the conversion speed, flow in and out without hands, effort, lightweight, easy handling, quick.
