record STA 22 – Automatic Sliding Doors

The Classic Linear Sliding Door Record STA 22 is a robust automatic sliding door system designed for special heavy‑duty applications where heavier door leaves and frequent use are required. It is available as a single‑leaf or double‑leaf configuration, supporting opening widths from around 800 mm up to approximately 3,000–4,000 mm and door weights of up to about 1 × 250 kg or 2 × 200–250 kg, depending on the variant. The STA 22 operator technology is engineered for long‑term reliability, with a compact 200 mm‑high drive unit that can be mounted on the lintel, freestanding, or integrated into the ceiling.

This sliding door system features low‑noise running thanks to short‑pitch tooth belts, low‑momentum rollers, and acoustically decoupled running tracks, delivering a sleek, elegant appearance and quiet operation suitable for high‑traffic entrances. The STA 22 is built on a modular Record system that simplifies installation and maintenance while meeting industrial machine‑safety guidelines and national standards. It can be combined with a range of sensors, push‑button stations, and security accessories, making it a versatile automatic sliding door solution for demanding commercial, industrial, and institutional applications.
