Auto Recovery Doors

Cronax High-Speed Auto Recovery Doors are engineered for industries that demand reliability, efficiency, and continuous operation. These doors are designed with an advanced self-repairing system that automatically realigns the curtain into the side guides after an accidental impact—eliminating downtime, costly repairs, and safety risks. With rapid open-and-close cycles, they help streamline traffic flow, reduce energy loss, and maintain controlled environments by protecting against dust, humidity, and temperature fluctuations.

Their springless design ensures smooth, noise-free movement and reduces wear, making them ideal for high-frequency usage. Constructed from heavy-duty, flexible PVC fabric and reinforced with industrial-grade components, Cronax Auto Recovery Doors deliver exceptional durability and long service life. The doors are equipped with advanced safety features such as motion sensors, soft-edge technology, and anti-crash protection to safeguard personnel and equipment.

ENGINEERING HIGHLIGHTS
SMART CONTROL SYSTEM
CUSTOMIZATION OPTIONS

Door Type	Self-repairing high-speed roll-up with flexible PVC curtain and zipper/zip-in guide technology for automatic re-insertion after impact.
Application	Internal or semi-exposed zones requiring fast logistics flow, energy control, hygiene, and low downtime (food, pharma, distribution, light manufacturing).
Clear Opening (Standard)	Up to approx. 4500 mm (W) × 4500 mm (H), model-dependent; larger custom formats available on request (up to ~8000 × 8000 mm depending on spec and site conditions).
Opening / Closing Speed	Opening up to ~2.0 m/s; typical closing ~0.5–0.8 m/s (inverter controlled; adjustable by application).
Wind Resistance	Engineered for EN wind classes ~2–3 depending on size and configuration; consult project data for exact class at selected dimensions.
Compliance & Safety	Designed in line with EN 13241 requirements for industrial doors; CE-markable configuration with appropriate safety devices.
Curtain Construction	High-tenacity PVC (approx. 0.9–1.5 mm) with welded reinforcement; no metal bars inside the curtain for safer impact behavior.
Vision Panels	Transparent PVC windows (~2.0 mm) in rectangular/oval/round layouts for safe cross-traffic visibility.
Side Guides	Low-friction polymer (UHMWPE) wear surfaces with self-repairing zip profile; optional brush/seal packages for enhanced tightness.
Guide / Structure Materials	Galvanized steel, powder-coated steel, or stainless steel (304/316) for hygiene/corrosion environments.

Power Supply	230 V single-phase or 400/415 V three-phase (regional availability); VFD drive for soft acceleration and deceleration.
Operator & Protection	Sealed drive unit; typical Operator IP54 / Control enclosure IP54–IP65 (selection per environment).
User Controls	Open/Stop/Close station as standard; options include pull-cord, key switch, wave sensor, remote, and PLC interlocks.
Activation & Traffic	Radar/motion sensors, induction loop, forklift presence sensors; LED traffic lights and audio-visual alerts for one-way or interlocked flows.
Safety Monitoring	Safety light curtain or multi-beam photo-eyes; wireless bottom safety edge; obstruction detection with auto-stop and re-open logic.
Position Control	Encoder-based / electronic limits for precise travel and repeatable cycle speeds.
Auto-Recover Function	On curtain impact, fabric disengages from guides and re-inserts automatically on the next cycle—minimizing downtime and service calls.
Emergency Operation	Manual crank or chain (model-dependent); optional UPS/backup for controlled operation during power outages on large openings.

Curtain Colours	Standard industrial palette with custom RAL on request; high-visibility tones for safety lanes or zoning.
Window Styles	Rectangular, oval, round, or full-width vision panels; multi-row windows for pedestrian zones and cross-aisle traffic.
Special Fabrics	Low-temp, anti-static, food-grade, or insulated curtains; optional mesh insert for ventilation where pressure balance is needed.
Structure Finish	Galvanized / powder-coated steel in project colour; stainless steel 304/316 for hygiene and corrosive atmospheres.
Sealing Packages	Enhanced side/top/bottom seals for controlled environments; air-loss reduction kits for energy-sensitive areas.
Branding	Custom logos, hazard chevrons, zone IDs, and process signage printed on the curtain.
Integration	Interface with access control, dock equipment, door-to-door interlocks, and BMS/PLC signals for plant logic.
