Supplier's note

  1. Three Technical Breakthroughs:

    • Fireproof Certification: UL 10C compliance (Pro Model) triples industry-standard fire resistance duration, enabling safe use in high-risk zones.
    • Hydraulic Precision: Adjustable damping reduces energy consumption by 20% compared to pneumatic systems.
    • Universal Adjustability: 0°–120° angle range accommodates uneven door frames or specialized accessibility requirements.

  2. Optimal Version Selection:

    • Base Model: Ideal for standard office doors (≤150 kg) where basic automation suffices.
    • Advanced Model: Recommended for retail or hospitality environments requiring medium-duty force and faster response times.
    • Pro Model: Best for hospitals, data centers, or high-security areas needing extreme durability and fire resistance.

With the Pro Model’s 90-minute fire rating, you can ensure compliance in critical infrastructure. Pair its heavy-duty capacity with adjustable force to handle fire doors in warehouses or industrial facilities. The Advanced Model’s 20% faster response time than Base models improves accessibility in public spaces.
