Key features and benefits
Rapid response to seize the golden escape window
In the event of a fire, smoke exhaust windows must open in the shortest possible time. Our linear actuators feature extremely fast response times; the time from when the fire control system issues a command to when the window sash is fully open is extremely short. This ensures that smoke and toxic gases are rapidly expelled outdoors during the early stages of a fire, securing a valuable "golden escape window" for occupant evacuation.
Precise stroke control for stepless adjustment of opening angles
Smoke exhaust windows and skylights require precise control of their opening angles depending on the application—a small opening angle for routine ventilation and a full opening angle for smoke exhaust during a fire. Our linear actuators provide precise stroke control and extremely high repeatability, allowing the window sash to stop precisely at any angle to meet diverse needs ranging from routine low-level ventilation to emergency full smoke exhaust.
High protection rating, confidently withstands harsh outdoor environments
Smoke exhaust windows and skylights are constantly exposed to the outdoor environment, facing the challenges of harsh natural conditions such as wind, sand, rain, snow, high temperatures, and extreme cold. Our linear actuators feature a high protection rating (IP66 or higher), providing full protection against dust and rain intrusion. Featuring an extruded aluminum housing and anti-corrosion treatment, they operate stably across a wide temperature range from -20°C to +65°C, ensuring the actuators reliably execute every opening and closing command regardless of extreme cold or heat.
Long service life and maintenance-free operation, reducing total cost of ownership
Building smoke exhaust windows and skylights are often installed in hard-to-reach high locations or within curtain wall structures, making routine maintenance extremely inconvenient. Our linear actuators feature a maintenance-free design, eliminating the need for periodic lubrication or replacement of wear-prone parts. The all-electric solution requires no hoses, pumps, or compressors, completely eliminating the risk of oil leaks in hydraulic systems and the issue of aging piping in pneumatic systems. Validated through tens of thousands of endurance tests, they ensure stable operation throughout the building's entire lifecycle, minimizing maintenance requirements.
Quiet operation that does not disrupt daily activities inside the building
Daily ventilation adjustments for smoke exhaust windows and skylights often take place during normal building operations, making them highly sensitive to noise. Our linear actuators maintain low noise levels during operation; whether during shopping mall business hours or office hours, the opening and closing of window sashes is silent, ensuring that the normal work and daily lives of building occupants remain undisturbed.
Built-in Hall sensors empower customers with precise control
Our actuators feature built-in Hall sensors that provide real-time feedback on the actuator's travel position and operating status via pulse signals. A building's fire control system or building automation system can use this data to precisely monitor the real-time opening angle and status of the window sash, enabling accurate closed-loop control. The real-time feedback from the Hall sensors provides a precise basis for the reliable execution of fire safety interlocks—from routine ventilation adjustments to confirming full opening for emergency smoke exhaust, every step is executed with precision under closed-loop control.
Flexible customization to suit diverse window types and installation spaces
Different buildings vary significantly in terms of window structure, opening angles, and installation space. We offer a wide range of actuator stroke options (20–500 mm) and customized installation services, enabling tailored solutions for various window types—including top-hung, bottom-hung, center-hung, sliding, and skylight windows—to ensure seamless integration between the actuator and the window frame structure.
Richmat's engineers provide end-to-end technical support—from needs assessment and solution design to product delivery—using reliable linear drive systems to safeguard every moment of ventilation and safety.
