Double Automatic Photocell Door
The Madoors USA Double Automatic Photocell Door is a double-wing automatic sliding door system engineered for pedestrian-heavy commercial, healthcare, retail, and institutional entrances where hands-free hygienic access, space efficiency, weather protection, and architectural elegance are simultaneously required. Activated by radar or hand sensor without any physical contact, the double-wing photocell sliding door eliminates the hygiene risk of contact at high-traffic entry points — making it an essential installation at hospitals, WC entrances, supermarket gates, and any facility where zero-contact entry is a hygiene or operational requirement.
Unlike hinged doors that scan a significant floor area during opening and closing — creating both space loss and collision risk in busy pedestrian environments — the double-wing sliding door requires no floor sweep space, reduces lost floor area, and eliminates the 'left the door open' problem in all weather conditions without requiring any personnel to manage the door. Available in any RAL color, compatible with all architectural designs, and delivering high levels of comfort, safety, reliability, and energy savings, the Madoors USA double automatic photocell door adds comfort and elegance to any entrance while operating reliably in every environment.
TECHNICAL SPECIFICATIONS
The Madoors USA Double Automatic Photocell Door is a double-wing bi-parting sliding door system — both wings open simultaneously from the center, sliding to opposite sides of the opening to create the maximum clear passage width, and closing automatically after the pedestrian has passed. The bi-parting double-wing configuration provides the widest possible clear opening from a given door frame width while minimizing the run-back space required on each side compared to a single-leaf sliding door of equivalent opening width.
Activation is provided by radar sensors — detecting approaching pedestrians before they reach the door and initiating opening in advance of arrival — and hand sensors — providing deliberate activation for controlled entry points where sensor-triggered automatic opening is preferred over approach-detection activation. Both sensor types provide completely hands-free, zero-contact door operation.
The door control system features real-time logic that continuously monitors door position, pedestrian traffic flow, and sensor status — adjusting opening speed, hold-open time, and closing speed in real time to match actual traffic conditions. Safety systems prevent door closure while any person or object is detected in the door opening. The slim profile frame design maximizes the glazed surface area of the door, maintaining the visual openness and natural light transmission of the entrance while minimizing the visual impact of the door hardware.
Door frames are available in any RAL color through electrostatic powder coating — allowing the door specification to match any architectural color scheme or branding requirement without constraint from standard color options. All Madoors USA sliding doors are designed to provide superb energy savings through tight weather sealing when closed, high-performance brushes and seals at the door perimeter, and minimal air exchange during rapid open and close cycles.
KEY FEATURES
Zero-Contact Hygienic Entry — Radar & Hand Sensor Activation
The door opens without any physical contact from the approaching pedestrian — activated by radar detection of the approaching person or by a hand sensor wave for deliberate controlled activation. Zero-contact operation eliminates the germ and contamination transmission risk of door handle and push-plate contact at high-traffic entry points — making automatic photocell doors the essential hygiene solution for hospitals, medical facilities, food retail, public WC entrances, and any facility where infection control and hygiene standards govern entrance design.
Double-Wing Bi-Parting Configuration — Maximum Clear Opening
The double-wing bi-parting configuration opens both door leaves simultaneously from the center — creating the maximum possible clear passage width in the minimum time while requiring only half the run-back space on each side compared to a single-leaf sliding door of equivalent opening width. The double-wing opening simultaneously accommodates bidirectional pedestrian traffic flow — entry and exit at the same time — without creating pedestrian collision or queuing at the door opening.
No Floor Sweep — Space Efficiency vs Hinged Doors
The sliding door mechanism requires no floor sweep area for door leaf travel — the door slides parallel to the wall rather than swinging across the floor. This elimination of floor sweep space directly reduces the area lost to door operation, increases usable floor area in the entrance zone, and eliminates the collision hazard between the opening door leaf and approaching pedestrians that makes hinged doors operationally unsafe in high-traffic entrance environments.
Eliminates 'Left Open' Problem — All-Weather Climate Control
The automatic closing mechanism ensures the door returns to the closed position after every pedestrian pass — eliminating the energy loss, climate control failure, and weather ingress caused by manually operated doors that are routinely left open in busy retail, healthcare, and institutional environments. This automatic close function maintains the interior climate of the building consistently throughout all traffic conditions without any personnel management.
Real-Time Logic Control — Intelligent Traffic Management
The real-time logic control system continuously monitors pedestrian approach, door position, traffic flow, and sensor status — adjusting opening initiation timing, hold-open duration, and closing speed in real time to match actual instantaneous traffic conditions. During high-traffic peaks, the door remains open longer to accommodate continuous pedestrian flow. During low traffic, the door closes promptly to minimize energy exchange. This intelligent real-time adaptation optimizes both traffic throughput and energy efficiency simultaneously.
Slim Profile Design — Architectural Elegance
The slim frame profile maximizes the glazed surface area of the door panel, creating a visual impression of maximum openness and transparency at the entrance while minimizing the visual mass of the frame hardware. The slim profile is specifically suited to modern glass facade architectures where conventional framed door systems would interrupt the continuous glazed appearance of the building facade.
Any RAL Color — Architectural Design Flexibility
Door frames and visible hardware are available in any RAL color through electrostatic powder coating — providing complete architectural design flexibility for color-matched or contrasting entrance specification across retail, corporate, healthcare, and institutional building types. Standard anodized aluminum and stainless steel finishes are also available for premium contemporary entrance applications.
Energy Saving — High-Performance Sealing
The door system is engineered for superb energy savings through high-performance perimeter brush and seal systems that minimize air infiltration when the door is in the closed position, and through rapid open and close cycle times that minimize the duration of the open air exchange period during each pedestrian pass. In climate-controlled facilities — hospitals, food retail, hotels, offices — these energy saving characteristics directly reduce heating and cooling operating costs throughout the building's operational life.
Absolute Safety — Obstruction Detection Throughout Travel
Safety systems monitor the door opening continuously throughout the closing cycle, detecting any person or object in the door travel path and halting the closing movement instantly. This absolute safety protection covers the full range of pedestrian types encountered at public entrance doors — including children, users with mobility aids, and users carrying wide or tall objects — ensuring that no one is caught by the closing door under any traffic condition.
Reliable Operation — Any Environment
The Madoors USA automatic sliding door is designed to operate at its best in any environment — covering the temperature extremes, humidity ranges, and contamination conditions encountered across all geographic locations and building types. Environmental performance reliability ensures consistent door operation across all seasonal conditions without requiring climate adjustments to the drive or control system.
ASSEMBLY & INSTALLATION SEQUENCE
Opening Assessment & Door Specification
