record STA 21 – Automatic Sliding Door

The record STA 21 is a versatile automatic sliding door system designed for light to medium‑heavy applications, offering quiet, reliable operation with a sleek, modern appearance. Built on the proven record system 20 platform, it uses smaller, lighter motors and an adapted control unit to deliver smooth, whisper‑quiet running while remaining suitable for frequent use in residential and commercial entrances. The system supports opening widths from about 800 mm up to 2,500 mm, with single‑leaf or double‑leaf configurations and typical door‑leaf weights of up to 1 × 120 kg or 2 × 75–80 kg, depending on the variant.

The STA 21 features self‑learning capabilities that optimise door movements and help prevent unwanted “ghost‑opening” by recognising the door’s own motion and external traffic patterns. It is engineered to meet common safety standards such as EN 16005 and includes interference‑resistant sensor integration, adjustable operating modes, and failsafe motor braking, making it ideal for both private homes and light‑traffic commercial spaces that require a blend of aesthetics, safety, and long‑term reliability.
