Olide Double Chain SD500 Automatic Window Opener

The Olide Double Chain SD500 is a high-torque, industrial-grade solution designed for the automation of heavy-duty and wide-span windows. Engineered with a dual stainless steel chain mechanism housed in a robust 1155mm aluminum casing, it delivers a powerful 80kg lifting capacity and a generous 500mm stroke. This 24V DC actuator is specifically designed to provide balanced force distribution, preventing sash warping in oversized top-hung, casement, or skylight installations while maintaining a sleek, powder-coated aesthetic.

Quick Answer

The Olide SD500 is best used for heavy windows (up to 80kg) and wide skylights that require a 500mm opening distance and dual-point stability to ensure smooth, balanced operation.

✓Heavy-Duty 80kg Load Capacity: Engineered to handle oversized glass and commercial-grade frames.
✓Dual Stainless Steel Chain System: Provides synchronized lifting to prevent window sash misalignment.
✓Extended 500mm Travel Distance: Offers maximum ventilation and airflow for high-ceiling or large-scale installations.
✓Precision 24V DC Motor: Delivers a consistent 7mm/s opening speed with low-voltage safety and efficiency.
✓Rugged Aluminum Housing: Features a silver powder-coated finish and IP42 weather resistance for durability.

Choose the Olide SD500 if you are automating a window wider than 1200mm or weighing up to 80kg. Its double-chain design is the only reliable way to ensure a heavy or wide sash stays level during its 500mm travel cycle.

✓ Who Should Buy

  • •Commercial contractors installing heavy-duty ventilation in offices or warehouses.
  • •Homeowners with large, hard-to-reach skylights requiring automated airflow.
  • •System integrators looking for a reliable 24V DC actuator for building management systems.

✕ Who Should Avoid

  • •Users with small, lightweight windows (under 30kg) where a compact single-chain actuator would suffice.
  • •Environments requiring IP67 ratings for direct, unprotected exposure to torrential rain.
Product Overview
The Olide SD500 stands out in the Double Chain Series as a premier choice for architectural automation. Unlike single-chain actuators that may struggle with the 'racking' effect on wide windows, the SD500 utilizes two distinct chain points to distribute pressure evenly across the frame. This ensures that even heavy top-hung or swing windows open and close with perfect horizontal alignment, extending the lifespan of the window hinges and seals. The 1155mm length of the actuator provides a stable mounting surface, making it ideal for large-scale residential and commercial projects. Functionally, the SD500 is built for longevity. It operates within a wide temperature range of -10°C to +70°C, making it suitable for diverse climates. While it comes standard with wired control, its 24V DC architecture allows for easy integration into smart home systems or optional remote control modules. The inclusion of a manual override ensures operational safety, allowing for window management even in the event of a power failure or technical maintenance.

Engineering Analysis
The SD500's internal engineering centers on a synchronized planetary gearbox that drives the twin chains at a matched rate of 7mm/s. This mechanical precision is critical for the 500mm extension, as any deviation between the two chains could lead to frame twisting. The use of stainless steel for the chains offers superior tensile strength and corrosion resistance compared to carbon steel alternatives. From a safety perspective, the integrated safety stop mechanism monitors current spikes to detect obstructions, instantly halting the motor to prevent structural damage or injury.
