Olide Double Chain SD300 Automatic Window Opener

The Olide Double Chain SD300 is a high-performance 24V DC motorized actuator engineered specifically for wide and medium-weight windows that require superior lateral stability. Unlike single-chain alternatives, its dual-chain synchronization ensures a balanced push-pull force, making it an elite choice for top-hung, casement, and skylight applications where structural integrity and smooth operation are paramount. With a 60kg load capacity and a sleek 955mm aluminum housing, it blends architectural aesthetics with industrial-grade reliability.

Quick Answer

The SD300 is best suited for automating wide casement or top-hung windows weighing up to 60kg, requiring a 300mm opening span for optimal ventilation in smart homes or commercial buildings.

✓Reinforced stainless steel double-chain mechanism for maximum stability on wide frames.
✓High-torque 24V DC motor providing a consistent 60kg load capacity.
✓955mm ultra-slim aluminum housing designed for discreet surface mounting.
✓Integrated safety-stop mechanism to prevent motor overload and window frame damage.
✓Wide thermal operating range from -10°C to +70°C for diverse climatic durability.

Choose the Olide SD300 if you are automating a window wider than 1000mm or weighing up to 60kg. Its double-chain stability and high-grade aluminum build offer a level of mechanical security that single-chain actuators simply cannot match, making it the definitive choice for long-term reliability.

✓ Who Should Buy

  • •Homeowners with high-reach skylights or heavy casement windows requiring automated ventilation.
  • •Commercial facility managers looking for 24V DC actuators compatible with building automation systems.
  • •Architects seeking a sleek, surface-mounted solution for wide-span window automation.

✕ Who Should Avoid

  • •Users requiring a high-speed opening (8mm/s is optimized for torque, not velocity).
  • •Installers who do not have access to a 24V DC power transformer or controller.
Product Overview
The Olide SD300 represents a significant advancement in window automation, moving away from flimsy single-chain units to a robust double-link stainless steel architecture. This model is specifically designed to handle the torsional stress associated with wider window sashes. Its 955mm length ensures that force is distributed more evenly across the window profile, preventing the 'warping' effect often seen in motorized heavy-duty glazing. The powder-coated silver finish provides a professional, modern look that fits seamlessly into both residential smart homes and commercial office environments. Functionally, the SD300 operates at a controlled speed of 8mm per second, emphasizing torque and safety over raw speed. This steady movement is ideal for maintaining the longevity of the window hinges and the actuator itself. The 24V DC power requirement makes it highly compatible with standard building management systems (BMS), smoke ventilation controllers, and smart home hubs, offering a versatile foundation for any automated climate control strategy.

Engineering Analysis
The internal components of the SD300 feature a high-efficiency electric chain motor coupled with a stainless steel double-chain assembly that is rated for 30,000+ cycles. The 300mm travel distance (stroke length) is optimized for 24V systems where current draw must remain stable—the SD300 manages high-load operation without significant voltage drops. Its IP42 weather resistance rating ensures protection against solid objects and vertically falling water drops, making it suitable for indoor environments and sheltered skylights. The inclusion of a manual override is a critical safety feature, allowing for window operation during power outages or system maintenance.
