Operation Theatre (OT Doors)

Cronax Operation Theatre Doors are specifically designed to meet the stringent requirements of modern healthcare facilities, ensuring maximum hygiene, safety, and efficiency in critical environments. Built from stainless steel, high-pressure laminate (HPL), or powder-coated galvanized steel with smooth, non-porous surfaces, these doors are resistant to microbial growth, chemical cleaning agents, and frequent sterilization procedures.

Engineered with hermetic sealing, flush-mounted designs, and silent operation, OT doors help maintain sterile zones and reduce contamination risks during medical procedures. Cronax OT Doors can be customized with vision panels, touchless operation, lead-lined protection, and interlocking systems to enhance workflow, safety, and compliance in hospitals, ICUs, cath labs, and diagnostic centers.

TECHNICAL SPECIFICATIONS

Door Type / Configuration	Single-leaf swing, double-leaf swing, automatic hermetic sliding, telescopic sliding, or bi-parting sliding (depending on corridor width and traffic)
Clear Opening Dimensions	Typical: 1,200 mm to 1,800 mm (single leaf) or up to 2,400 mm+ (double/bi-parting) width × 2,100 mm to 2,500 mm height. Custom sizes beyond this as required.
Leaf / Panel Thickness	40 mm to 60 mm (typical); heavier doors with additional layers (e.g. radiation shielding) may be 60 mm+
Leaf Construction / Material	• Rigid core (e.g. aluminium honeycomb, high-density foam, steel or aluminum core) • Outer skins: stainless steel (e.g. SS 304 / 316), HPL (high-pressure laminate), antimicrobial laminate, FRP, or coated steel • Seamless or flush surfaces to avoid microbial traps
Frame / Door Jamb	Stainless steel or aluminium frame, flush or rebated, with continuous gasketing / seals. Compatible with wall thickness and finish.
Seal & Airtightness (Hermetic Closure)	• Continuous perimeter seals (neoprene, silicone, EPDM) • Drop-down / retractable bottom seal for sliding doors to engage floor • Achieve tightness class (e.g. > 99 % seal efficiency) to maintain pressure differential. • Smoke / air infiltration control (< small leakage)
Operating / Drive Mechanism	• Swing doors: low-energy door operator or full-energy drive with pneumatic or electromechanical actuator • Sliding / telescopic: electric motor + drive gearbox, belt/chain/roller system • Soft-start / soft-stop control to prevent slamming • Manual override (push / pull, chain hoist) in power loss condition • Sensors (motion, presence, safety-edge, IR photocell)
Operating Speeds & Timing	• Opening speed: typical 150 mm/s to 300 mm/s (adjustable) • Closing speed: 100 mm/s to 300 mm/s (adjustable) • Hold-open / dwell time: 1 to 8 s (or adjustable) • Manual push force: < 100 N (for swing leaf)
Duty Cycle / Usage	Heavy duty daily cycles (multiple open/close per hour). Designed for continuous hospital operation with minimal downtime.
Vision Panels / Windows	• Flush-embedded glazing: tempered glass, laminated safety glass, or polycarbonate (5 mm – 8 mm) • Optional electropolarized glass, internal Venetian blind, or switchable privacy glass • Flush or minimal protrusion design to ease cleaning
Radiation / Lead Lining (Optional)	• Lead sheet / composite shielding integrated in door leaf and frame for operating rooms with imaging/X-ray use • Lead thickness 1 mm to 4 mm (or as per required radiation shielding)
Fire & Smoke Rating (Optional)	• Fire-rated door versions (F30, F60, etc.) with concealed intumescent seals in leaf and frame • Smoke seals / gasketing to limit smoke passage • Gap control at meeting edges & bottom (e.g., ≤ 3 mm or per code)
Hygiene & Cleanability	• Seamless, flush surfaces, coved edges • Antimicrobial coatings or finishes • Smooth surfaces (no pores, cracks) • Durable surfaces resistant to disinfectants, chlorine, alcohols • Minimal joints / screws exposed
Integration & Controls	• Control panel with soft-start/stop, overload protection, programmable logic • Integration with room pressure control / BMS (building management system) • Activation: push-button station, key switch, RFID / badge reader, motion sensor, foot switch, voice / touchless sensor • Safety: auto-reverse edges, obstruction sensors, photocells, emergency stop • Encoder or limit switches for precise positioning
Emergency / Backup Operation	• Manual mode (push / pull) in case of power failure • Battery / UPS backup to allow some operations during outage • Mechanical override/chain or crank for swing doors • Fail-safe (spring/return) or fail-secure (lock) options as needed
Finish & Surface Treatments	• Stainless steel with satin / brushed / polished finish • Powder-coated steel / aluminium (hospital-grade / epoxy) • HPL / phenolic laminate with antimicrobial properties • Color options (RAL) for visual coding • Protective coatings (anti-scratch, anti-graffiti)
Accessories & Add-ons	• Canopy hood or cover for sliding tracks • Kick plates / push plates (stainless / polymer) • Integrated LED lighting / status indicator strip • Door signage / wayfinding integration • Flush drip rails, drip edges to direct fluid away • Seals for acoustic isolation (if needed)
Standards & Compliance	• Must comply with hospital / medical facility codes, cleanroom / ISO class standards • EN / ISO standards for hermetic doors (e.g. EN 12207, UNE-EN 16005) • Local fire & building code compliance • EMC / electrical safety standards for operators • Infection control / sterilization standards
