BOXTWOFOLD
BOXTWOFOLD double-layer folding high-speed PVC doors are made from 900 gr/m² PVC tarpaulin material. The double-layer PVC tarpaulin is reinforced with 120x55 aluminum extrusion bars mounted at four separate points. The doors operate on the principle of pulling the double-layer PVC curtain mechanism upwards from below using reinforced aluminum bars. This is achieved by means of belts wound around a shaft, and a gearbox and motor connected to the shaft drive the galvanized uprights on either side, which in turn move along the guide rails.







- Door left and right guides must be made of 2.5mm thick, DX51DZ quality galvanized sheet metal, with dimensions of 170x210x170mm and length adjusted to the door dimensions, and must have a custom shape suitable for the door.
- The upper assembly of the door must be made of 2.5mm thick DX51DZ quality galvanized sheet metal, with dimensions of 170x210x170mm, and a width adjusted to the door dimensions. The drum carrier and rope winding system inside must be made of specially formed, laser-cut galvanized 3mm sheet metal.
- PVC tarpaulin must be a double-layered tarpaulin, bonded at four points using ultrasonic welding, conforming to DIN ISO 2040, DIN ISO 2075, DIN EN 1876/2 1998 standards, EU 1935/2004 and 10/2011 food standards, phthalate-free, with 1100 dtex weft, 1100 dtex warp, UV stabilized, CE certified, and 900 g/m2 hydrolytic resistant technical textile. It must withstand temperatures between -30 and +70 degrees Celsius without deformation.

- The door's impact-resistant safety system must be designed to break open in the event of an accident (such as a vehicle impact) without damaging the aluminum bar system. It must also be wind-resistant and made of PVC POM material, capable of withstanding temperatures between -30 and +70 degrees Celsius without deformation.
- The door must have a 4-point connected, double-layered tarpaulin surface and an aluminum bar system made using a waste-free aluminum extrusion method with a 120x55 profile cross-section to increase wind resistance. It must be able to meet wind resistance values of 700 Pa (123 km/h) for widths up to 3 meters, 600 Pa (113 km/h) for widths between 3.01 and 4 meters, 500 Pa (103 km/h) for widths between 4.01 and 5 meters, and 450 Pa (99 km/h) for widths between 5.01 and 12 meters.
- PVC tarpaulin; The transparent viewing windows to be applied to it must comply with EN 71-3 standard, EU 1935/2004 and 10/2011 food standards, be phthalate-free, 1.5-2mm thick, and withstand temperatures between -30 and +70 degrees Celsius without deformation.
- The door guide surface must include a reflective safety photocell with a capacity of 1-10 meters, conforming to the IEC 60529 IP64 standard, and capable of 5,000,000 operation cycles in working conditions between -30 and +70 degrees Celsius, along with a PVC POM housing to protect the photocell and reflector.
- The motor should be a three-phase 230-400V AC IE3 class, energy efficient, with a power output between 0.75kw and 4kw, adjustable according to door dimensions.
- The engine must have a cooling system.
- The motor brake must have a response time of 0.2 ms, be 110V-220V, and allow manual shutdown via a brake release lever.
- Depending on the dimensions of the installation location, the door opening speed should be between 0.40 m/s and a constant speed of 25 m/s.
- The switch module mounted on the gearbox controls the up-down level and the precision of the door's stopping points.
- The switch system must comply with IP 51 (CEI EN 60529), EN 60947-5-1, CEI EN 60947-5-1 EN60529, CSA 22.2-14 standards and have a capacity of 2,000,000 cycles under operating conditions between -30 and +70 degrees Celsius.
- The door's control panel must be a 30x40 plastic panel conforming to EN ISO 12100 Machine Safety standards, using Hyundai or LG switchgear and V23 microcontrollers.
- The door must have a safety system that automatically cuts off the electrical circuit while it is in use.
- The door control panel; a 380V AC control panel with an LCD screen or similar display should be supplied with the door.
- The door must have an automatic closing feature adjustable from the control panel.
- The door's motor operating time is adjustable from the control panel.
- The door should be able to be opened, closed, and stopped via the control panel.
- The door must have a button with up and down controls, in addition to the controls on the control panel.
- The door must have an EMERGENCY STOP button on the control panel.
- The door's airlock system must be integrated into the control panel.
- The door must have an identification label on the control panel containing the production date, serial number, and manufacturing dimensions.
