In industrial facilities where explosion risk is high — petrochemical plants, refineries, chemical processing facilities, pharmaceutical manufacturing, grain handling, paint spray facilities, and mining operations — the use of ATEX certified door systems is not optional. It is a legal and operational safety requirement. The Madoors USA ATX-SD-4000 series delivers this compliance through purpose-built explosive atmosphere design, high-quality durable materials, and verified ATEX certification documentation.
TECHNICAL SPECIFICATIONS
The ATX-SD-4000 Series is designed and tested in accordance with ATEX directives governing equipment and protection systems for use in explosive atmospheres. ATEX certification confirms that the door system — including all mechanical, electrical, and drive components — is engineered to eliminate ignition sources that could trigger an explosion in the presence of flammable gases, vapors, liquids, or combustible dusts in the surrounding atmosphere.
All components of the ATX-SD-4000 series — including the sectional door panels, guide track system, drive mechanism, electrical wiring, motor, control unit, and hardware — are specified and manufactured to eliminate static discharge, electrical sparking, and mechanical impact ignition risks in the hazardous zone classification of the installation. The door system operates as a sectional overhead door, with panel sections traveling vertically in guide tracks to open and close the industrial entrance — providing the large-format opening clearance required for vehicle and material movement in industrial facilities while maintaining the explosive atmosphere safety performance required by ATEX certification.
The ATX-SD-4000 series is manufactured from high-quality, durable materials selected for long service life under the heavy-duty operational conditions of active industrial facilities. Various models within the ATX-SD-4000 range are available to suit different hazardous zone classifications, opening dimensions, operational cycle requirements, and industrial application types — providing configuration flexibility for the full range of ATEX-certified industrial door applications.
KEY FEATURES
ATEX Certified — Explosive Atmosphere Compliance
The ATX-SD-4000 series is fully ATEX certified, confirming conformity with EU ATEX directives for equipment and protection systems operating in explosive atmospheres. ATEX certification is the legally required standard for industrial door systems installed in hazardous zones where explosive gases, vapors, liquids, or combustible dusts are present — providing facilities with the compliance documentation required for regulatory inspection, insurance, and operational license purposes.
Special Design for Explosive Environments
Every aspect of the ATX-SD-4000 door system is specifically engineered for explosive atmosphere safety — eliminating all potential ignition sources including static electrical discharge, electrical arcing, mechanical impact sparking, and surface temperature exceedance that could trigger an explosion in the presence of flammable or explosive atmospheres surrounding the door installation.
Ex-Proof Drive & Electrical Components
All electrical components of the ATX-SD-4000 system — including the motor, control unit, wiring, switches, and sensors — are explosion-proof (Ex-proof) rated, encapsulated, or otherwise engineered to prevent electrical ignition in the hazardous zone classification of the installation. Ex-proof electrical design is the primary engineering requirement distinguishing ATEX certified industrial doors from standard industrial door systems.
High Safety Standards — Explosion Risk Minimization
The ATX-SD-4000 series is produced in accordance with the highest applicable industrial safety standards to minimize the risk of explosion at the door installation point. The combination of ATEX-compliant design, Ex-proof electrical components, and non-sparking mechanical hardware eliminates the ignition risk sources present at the door opening — one of the most operationally active and frequently cycled points in any hazardous industrial facility.
High-Quality Durable Materials — Heavy-Duty Performance
ATX-SD-4000 series door panels and structural components are manufactured from high-quality, durable materials selected for long service life under the demanding physical, chemical, and environmental conditions of active petrochemical, chemical processing, pharmaceutical, and industrial manufacturing environments. Material selection eliminates corrosion, chemical degradation, and mechanical wear mechanisms that would reduce service life or compromise ATEX compliance performance over time.
Sectional Overhead Door Configuration
The ATX-SD-4000 operates as a sectional overhead door, with panel sections rising vertically into the overhead guide track system to open the entrance and descending to close. This configuration maximizes the clear opening width and height available for vehicle, forklift, and material movement while minimizing the floor space occupied by the door operation — a critical space efficiency requirement in active industrial production and processing environments.
Ease of Use & Maintenance
The ATX-SD-4000 series is designed for straightforward daily operation and accessible maintenance, ensuring that the operational demands of maintaining an ATEX-certified door system do not impose excessive burden on facility maintenance teams. Routine inspection and service of ATEX-certified components can be conducted by qualified maintenance personnel without specialized equipment beyond that required for standard Ex-proof electrical maintenance.
Various Models — Flexible Configuration
The ATX-SD-4000 range includes multiple models covering different ATEX zone classifications, opening dimensions, panel specifications, and drive system configurations — providing the configuration flexibility required to match the specific hazardous zone designation, physical dimensions, and operational requirements of each individual industrial facility entrance.
Employee Safety Enhancement
The ATX-SD-4000 series directly reduces the risk of explosion at door installation points, protecting employees working in and around hazardous industrial entrances from the injury and fatality risk associated with explosive atmosphere ignition events. Employee safety enhancement is the primary operational benefit of ATEX certified door installation in hazardous industrial facilities.
Equipment & Facility Protection
By eliminating ignition sources at industrial entrance points, the ATX-SD-4000 series protects the surrounding facility infrastructure, production equipment, stored materials, and structural fabric from the catastrophic damage caused by explosive atmosphere ignition events — reducing the financial and operational consequences of explosion incidents that would otherwise result in facility shutdown, equipment destruction, and extended production interruption.
Legal Compliance & Regulatory Requirements
The use of ATEX certified equipment in hazardous zones is a legal requirement under EU ATEX directives and equivalent national regulations in many jurisdictions worldwide. The ATX-SD-4000 series provides facilities with the certified, documented compliance required to satisfy regulatory inspections, occupational health and safety authority requirements, insurance underwriter specifications, and operating license conditions for hazardous industrial facilities.
ASSEMBLY & INSTALLATION SEQUENCE
Hazardous Zone Classification Assessment
The ATEX zone classification of the installation location is confirmed — Zone 0, 1, or 2 for gas and vapor atmospheres, or Zone 20, 21, or 22 for combustible dust atmospheres. The appropriate ATX-SD-4000 model and component specification for the confirmed zone classification is selected. Opening dimensions, operational cycle rate requirements, and drive system specification are confirmed.
Structural Opening Preparation
The structural opening is prepared to the specified dimensions for the selected ATX-SD-4000 model. Header clearance for the overhead track and panel stack is verified. All electrical supply runs to the door installation location are confirmed as appropriately rated for the hazardous zone classification before installation commences.
Guide Track Installation
Overhead guide track sections are installed on both sides of the opening, secured to the structural wall or header frame. Track alignment, plumb, and parallel spacing are verified across the full panel travel height. Track components are inspected for any burrs, sharp edges, or impact surfaces that could create mechanical sparking during panel operation.
Panel Section Installation & Connection
Sectional door panels are installed in sequence from the bottom of the opening upward, connected at the horizontal joints with the specified ATEX-compliant hinge hardware. Panel alignment within the guide tracks is verified at each section before proceeding to the next. All panel-to-panel hardware connections are inspected for correct installation.
Ex-Proof Drive System Installation
The explosion-proof motor and drive system are installed at the specified mounting position. All electrical connections — motor power supply, control wiring, limit switch connections, and sensor wiring — are completed using ATEX-certified wiring methods, cable glands, junction boxes, and termination hardware appropriate to the zone classification. No standard electrical fittings are used within the hazardous zone boundary.
Ex-Proof Control System Commissioning
The Ex-proof control unit is commissioned and door travel parameters — open speed, close speed, limit positions, and safety system responses — are programmed and verified. All electrical connections within the hazardous zone are inspected for correct ATEX-certified termination before power is applied.
Safety System Testing & ATEX Compliance Verification
All safety systems — obstruction detection, emergency stop, and anti-drop brake — are tested and verified. A qualified ATEX compliance inspection is conducted across all installed components, wiring methods, and enclosure integrity to verify conformity with the zone classification requirements. ATEX certification documentation for all installed components is compiled into the project handover package.
Operational Handover & Maintenance Documentation
Full operational testing is conducted across all open, close, safety response, and emergency stop functions.
