Fire & Heat Resistance: Curtain meets DIN 75200 flammability Class B1, withstanding 800°C for 30 minutes.
Enhanced Visibility: 1.2mm horizontal PVC window ensures safe traffic flow in low-light conditions.
Harsh Environment Durability: Stainless steel frame resists salt spray (1,000h ASTM B117) and humidity (up to 98% RH).
Smart Activation: Radar + manual switch modes reduce energy waste with 0.2s response time.
Seamless Integration: Modbus RTU protocol supports PLC/SCADA connectivity for Industry 4.0 facilities.
Oil & Gas Facilities: Fire-resistant curtains isolate drilling zones from storage areas (ATEX-compatible).
Automated Warehouses: Radar-triggered 2.5m/s mode aligns with robotic sorting systems.
Bakery Production Lines: Anti-static PVC prevents flour dust adhesion (HACCP compliant).
Pharmaceutical Packaging: Sealed edges block insect ingress (GMP Grade C/D environments).
Mining Operations: Corrosion-resistant components endure abrasive dust and humidity.
Compliance & Certifications
Material fire resistance: DIN 75200
Safety sensors: ISO 13849-1 PLc
Operational temperature range: -30°C to +70°C
Notes
Customizable curtain colors per client-provided RAL samples.
Optional upgrades: Thermal insulation layers, RFID access integration.
Does the PVC window maintain clarity after prolonged exposure to UV radiation or chemicals?
The 1.2mm anti-yellowing PVC strip retains 95% light transmission after 10,000 hours of UV exposure and resists oxidation from acids/alkalis (pH 3–11).
Can the radar sensor distinguish between small animals and humans to prevent false triggers?
Yes, the 24GHz Doppler radar detects objects ≥20cm in height, ignoring smaller debris or rodents while ensuring human/vehicle safety.
Is the door suitable for explosion-prone environments like oil refineries?
Optional ATEX-certified motors and non-sparking aluminum components are available for Zone 2 hazardous areas.
