Nekos Kimo 225 chain actuator

The Nekos Kimo 225 is a premier Italian-engineered chain actuator designed for high-performance natural and smoke ventilation. Boasting a robust 250N thrust capacity and a versatile stroke range of 200mm to 500mm, this actuator is housed in a sleek, powder-coated aluminum casing. It is specifically engineered to handle top-hung, bottom-hung, and skylight applications, providing a reliable automated solution for modern architectural climate control and emergency safety systems.

Quick Answer

The Nekos Kimo 225 is a 250N thrust motorized chain actuator used to automate medium-to-large windows (top-hung, bottom-hung, or skylights) for natural ventilation and smoke evacuation in both 24V DC and 230V AC configurations.

✓Powerful 250N thrust capacity for handling heavy window profiles and skylights.
✓Adjustable travel distance (200-500 mm) for precision opening control.
✓Durable extruded aluminum construction with a high-quality powder-coated finish.
✓Certified for dual-use: daily natural ventilation and emergency smoke extraction.
✓Integrated safety-stop mechanism and rain sensor compatibility for ultimate protection.

Choose the Nekos Kimo 225 if you require a high-end, Italian-made actuator that balances power (250N) with a refined aesthetic. It is the ideal choice for projects requiring certified smoke ventilation performance and adjustable stroke lengths for custom window opening angles.

✓ Who Should Buy

  • •Commercial developers looking for RWA-compliant smoke and heat exhaust ventilation solutions.
  • •Architects specifying sleek, surface-mounted automation for modern glass skylights.
  • •Smart home integrators requiring reliable 24V/230V wired actuators for natural climate control.

✕ Who Should Avoid

  • •Users looking for a DIY cordless/battery-powered solution, as this requires hard-wired installation.
  • •Outdoor installations exposed to heavy direct water spray exceeding the IP32 protection rating.
Product Overview
The Nekos Kimo 225 represents a sophisticated fusion of Italian design and industrial reliability. Engineered for the demanding requirements of the Kimo Series, this actuator utilizes a double-link stainless steel chain to ensure silent and smooth operation. Its slim profile allows for surface mounting without compromising the aesthetic integrity of the window frame. Whether integrated into a commercial building's smoke and heat exhaust system (RWA) or used for residential climate regulation, the Kimo 225 delivers consistent torque and long-term durability. Technically versatile, the Kimo 225 is available in both 24V DC for safety-critical systems and 230V AC for standard power grids. The IP32 weather resistance rating ensures protection against solid objects and light moisture, while the internal electronics manage a soft-stop closure to preserve the lifespan of the window gaskets. With its wide operating temperature range from -5°C to +65°C, it remains functional in diverse environmental conditions.

Engineering Analysis
The internal architecture of the Kimo 225 features a precision-machined gearbox that converts rotational energy into linear thrust with minimal noise. The obstacle detection system is a standout safety feature, utilizing current-sensing technology to halt the motor if resistance is met, preventing mechanical strain. Furthermore, the compatibility with external rain sensors via its wired control interface allows for a 'fail-safe' closing logic, ensuring that the interior remains protected even in the absence of manual intervention.
