Clean Room Roll-Up Doors

Cronax High-Speed Roll-Up Clean Room Doors are specially engineered to maintain the highest standards of hygiene, air pressure control, and contamination prevention in controlled environments. Designed for cleanrooms, pharmaceutical plants, laboratories, and electronics manufacturing units, these doors ensure seamless access while preserving strict environmental conditions.

Constructed with smooth, non-porous PVC curtain materials, these doors are resistant to microbial growth, chemical cleaning agents, and particle accumulation. Their airtight sealing system minimizes air leakage, ensuring proper pressure differentials are maintained between classified areas. With rapid open-and-close cycles, the doors reduce cross-contamination risks by limiting the time clean zones are exposed. This also improves workflow efficiency, reduces energy loss, and optimizes AHU performance.

ENGINEERING HIGHLIGHTS
SMART CONTROL SYSTEM
CUSTOMIZATION OPTIONS

Door Type	High-speed vertical roll-up door engineered specifically for controlled environments — smooth, low-particle curtain with precision guides to ensure repeatable sealing and minimal particle generation.
Primary Applications	Cleanrooms, pharmaceutical production, medical device assembly, aseptic zones, lab airlocks and food processing areas where contamination control and rapid throughput are required.
Available Sizes	Standard from small pedestrian clearances to large logistics openings — typical standard sizes up to ~1,000–6,000 mm (W) × 1,000–6,000 mm (H). Custom engineered sizes available on request.
Operating Speeds	Programmable opening speeds up to 1.2–2.0 m/s (model/option dependent) with controlled closing speeds (typically ~0.4–0.8 m/s) to reduce turbulence and pressure disturbance during cycling.
Air Tightness & Pressure	Designed for very low air-leakage configurations and to support pressure differentials in airlocks; precision edge seals and guide geometry reduce exchange when cycles occur.
Particle Control	Smooth, seam-minimizing curtain and edgeless guides that facilitate wipe-down and reduce particulate accumulation; constructed to meet hygiene best practices for controlled environments.
Durability & Duty	Industrial duty components and high-cycle drives suitable for frequent operation (tens of thousands to >100k cycles/year depending on specification).

Drive System	Inverter (VFD) controlled motor with soft-start / soft-stop and programmable acceleration and deceleration profiles to limit air disturbance and mechanical stress.
Power Options	Flexible supply configurations: 230 V single-phase (small units) or 400/415 V three-phase for larger openings and high-duty applications.
Control Unit	Microprocessor/PLC based controller with HMI options, diagnostics, event logging, cycle counters and optional network / BMS connectivity for central monitoring.
Activation Methods	Wave/hand-gesture actuators (contactless), radar/motion sensors, induction loops, push-buttons, and PLC interlocks for integration with process equipment and airlock logic.
Safety Systems	Multi-layer safety: thru-beam or reflective photo-eyes, safety light curtains, contactless safety edges, and torque/obstruction detection with immediate stop and controlled reverse where applicable.
Crash / Auto-Recover	Accident-forgiving curtain & guide arrangement: on impact the curtain can safely disengage and automatically re-seat or be reset on the next cycle — minimizing downtime and preserving seal integrity.
Environmental Protection	Control enclosures and operator housings rated up to IP54–IP65; optional heated components or trace heating for humidity control in adjoining zones.
Emergency Operation	Manual release & hand-crank options, plus optional UPS backup for controlled open/close during short outages in critical applications.

Curtain Materials	Hygienic PVC / polyurethane coated fabrics with low-outgassing and smooth surfaces; multi-ply, anti-microbial and FDA/GMP-compliant options available on request.
Guide & Frame Materials	Removable / smooth stainless steel (304 / 316) covers or full stainless construction for wash-down areas; anodized aluminum or powder-coated steel for lower-corrosion settings.
Surface Finish	Continuous, edgeless profiles and sealed covers to minimize crevices; finishes selected to permit frequent wipe-down and chemical disinfection without degrading materials.
Vision & Access	Flush vision strips (PVC or polycarbonate), full-width translucent panels or small sight windows engineered to avoid seams in critical zones; optional pedestrian pass-ports or interlocked man-doors.
Sealing Packages	Multiple seal choices — soft moulded bottom edge, foam compression seals, and full-height brush / gasket systems to match required leakage and pressure class.
Colour & Branding	Neutral, easy-to-clean colours standard (white, light grey) with RAL options and printed hazard/identification stripes if required by SOPs.
Accessories	LED traffic indicators, audible warnings, interlock relays, PLC interfaces, remote diagnostics, spare parts kits, and preventive maintenance packages.
Validation & Documentation	IQ/OQ/PQ support, FAT/SAT test records and material certificates available for regulated installations and qualification processes.
