Scope of use

The EFA-STT High-Speed Turbo Door is designed for use in industrial, commercial, and cleanroom environments where high-speed operation, durability, and safety are required. Typical applications include logistics centers, manufacturing facilities, warehouses, and controlled environments such as laboratories and food processing areas.

This door is intended for installation in vertical structural openings and is suitable for internal or external use, provided environmental conditions align with its performance specifications. It is particularly effective in maintaining controlled environments by reducing air exchange, dust ingress, and temperature loss.

Restrictions:

• The door must be installed in accordance with DIN EN 13241 and relevant local building codes.
• For external installations, wind load resistance up to Class 4 (DIN EN 12424) must be verified for site-specific conditions.
• The door’s thermal insulation (up to 6.4 W/m²K) is effective in minimizing heat transfer but may require additional insulation for highly sensitive thermal environments.
• Proper maintenance and operation per the manufacturer’s instructions are essential to ensure safe and efficient performance.
• Installation in areas with significant water exposure requires site-specific assessment, as the door has limited watertightness.

This product is not intended for residential use or for applications requiring prolonged exposure to corrosive environments without additional protective coatings.

Product Criteria

Design requirements

The EFA-STT High-Speed Turbo Door is designed for industrial and commercial use, suitable for internal and external applications such as manufacturing, logistics, cleanrooms, and warehouses. It is intended for vertical structural openings and must be installed per NZBC Acceptable Solutions and the manufacturer’s instructions.

The door features customizable dimensions, a galvanized or powder-coated steel frame, and anodized aluminum panels with transparent or opaque options. Accessories include safety light grids, mechanical locking mechanisms, and ventilation laths. Fixings must suit the structural substrate to meet wind load resistance up to Class 4 (DIN EN 12424).

Installation requires alignment with DIN EN 13241, a suitable power supply, and proper sealing to ensure thermal performance (DIN EN 12428) and water resistance (DIN EN 12489). Regular maintenance is essential for reliable operation and ongoing conformance with performance expectations.

Installation requirements

Efaflex STT doors should be installed by qualified technicians experienced in high-speed industrial doors. Installation involves securely mounting the frame, connecting and testing electrical components, and calibrating sensors. Adherence to manufacturer instructions, correct tool usage, and precise alignment are essential to prevent operational issues. Installation should take place in stable temperature and humidity conditions to avoid misalignment or material expansion. Ensuring proper calibration of sensors and components minimizes performance issues and maintains safety in temperature-sensitive applications.

Maintenance requirements

Preventative maintenance is suggested in accordance with Efaflex’s maintenance schedules to ensure durability and optimal performance. Recommended tasks include regular visual inspections, cleaning, and checks on wear-sensitive parts like seals and sensors. Adjustments to door tension and recalibration of automation features help prevent issues in high-use environments. Key components, such as springs, electrical connections, and safety edges, should be inspected periodically, with replacements as necessary to maintain longevity and functionality. Efaflex can recommend a qualified contractor to perform these tasks and keep detailed records to support NZBC Clause B2 compliance and ensure reliable door operation.

Warrantees

Efaflex offers a warranty covering manufacturing defects in materials and workmanship under normal use conditions. This warranty applies from the date of installation and requires adherence to Efaflex’s recommended maintenance schedule to remain valid. Any modifications, unauthorized repairs, or improper use will void the warranty. Efaflex recommends using certified technicians for maintenance and repairs to ensure continued compliance and performance.
