Thanks to the new features, Helix is now even more robust and requires less maintenance. At the same time, customers benefit from improved service. The new-version Helix spiral door has been available at the same price since the beginning of September. It can be retrofitted to the predecessor model.
Perfect combination
The Helix spiral door from Alpha Deuren in Didam, the Netherlands, has combined two systems since its market launch in 2015: As a high-speed door, it can be used during the day and at peak times. With opening times of up to 1.1 m/s per second, it is a real vertical starter and thus the ideal door system for applications where frequent operation is required, for example in logistics centres. On the other hand, thanks to the micro-profiled 40 mm ISO panels, the Helix door transforms into a robust and superbly insulating sectional door for situations where maintaining temperature is important.
Helix also has a special spiral track system with very small installation dimensions. The intelligent drive system with rotary chain technology eliminates the need for weight compensation with tension or torsion springs, which are also vulnerable. This makes Helix both space-saving and low-maintenance. With its compact design, the Helix spiral door is particularly suitable for rooms with low installation depths. Its areas of application are logistics, the automotive industry, mechanical engineering, the metal and electrical industries, food processing and the chemical and pharmaceutical industries.
Update achieves 40 000 cycles
As part of the update of the Helix spiral doors, newly reinforced roller holders, rollers and hinges were installed. These ensure that the current version is now even more robust and requires even less maintenance than the predecessor model. Whereas parts previously had to be replaced after 20 000 cycles, this is now only necessary after 40 000 cycles. This means lower maintenance costs. The new parts are compatible with the old version of the Helix door.
Safety first
Great emphasis was also placed on safety in the new edition of the Helix spiral door. The light barrier travelling in front of the gate edge detects obstacles immediately and ensures that the drive stops at once. This happens so quickly that there is no contact between door and obstacle. Telescopically extendable sensors or light grids integrated in the track system provide non-contact monitoring of the main closing edge. The door leaf has a thickness of 40 mm and a U value of 1.77 W/m2K (for door size 5 × 5 m with ISO panels). Slender ALU sections are available as glazing elements on request. With the service kit for quick and smooth repair of the runners, the Dutch company fulfils a wish frequently expressed by customers. The previously vertical running tracks on the door were replaced by split vertical running tracks especially for this purpose. The lower section corresponds to the height of the three lower panels, as these are often hit in the event of a collision. The built-in plastic and metal clips can be dismantled so that the chain guide can be removed and the repair completed in a short time. The service kit contains plastic and metal clips, service tool, chain guide block and the lower section of the track (left and right). The Helix service set is also attractively priced, plus it takes less time to replace the spare parts.
