•Patented Balancer: The core technology for arbitrary height hovering. The tension of the coil spring is precisely matched with the window weight accurate to pounds. A single coil spring can withstand more than 10,000 stretching times, with a theoretical service life of 27 years. The window sash can hover at any height even in power failure or equipment failure.
•24V Ultra-quiet Patented Motor: Compliant with EU export standards, it adopts safe low voltage and 20W low power with running noise as low as 10dB. Equipped with gear & rack mechanical lifting structure, it features stable meshing and high torque. The motor does not bear the window weight, greatly extending the service life, and supports obstacle stop and anti-pinch function.
•Universal Material & Craftsmanship: All series adopt 6063-T5 primary aluminum profiles, supporting fluorocarbon spraying and seamless welding. Transmission accessories are treated with high-frequency hardening. Standard configurations include broken bridge sound insulation & heat insulation, tight mullion sealing and bottom frame air tightness enhancement, delivering excellent wind resistance, water resistance and sound insulation performance.
•Safety Configuration: High-end series are equipped with triple safety protection, child lock and frame-wrapped sash anti-fall structure. Electric models support multiple intelligent control modes with detachable motors for easy maintenance.
