There are many different types door on the market that can be used for large openings. However, in situations where the frequency of the traffic through the doorway is high, it is inevitable that any slow action type of door will regularly be left in the open position. This not only compromises the security of the building, but also any dust or temperature control that might be necessary. This is not only a problem for climate- or pollution-sensitive areas, it can significantly increase the costs associated with heating a building in winter and cooling it during summer.
The simple solution is to install an Efaflex High Speed door available from DMF. These fast-acting doors are rigorously designed, precision manufactured, and offer an effective and reliable alternative to standard roller shutters or sectional type doors.
Efaflex is a German manufacturer of premium high-speed doors. The range includes spiral, roll up and folding door designs, and these can be used for indoor or external applications in all types of facilities, including warehouses, high-rise carparks, emergency facilities, correctional centres, production facilities and stores.
Efaflex doors provide highly secure access control thanks to their fast speed of opening and closing. With opening velocity of approximately two metres per second, Efaflex doors minimise the time the door is open and therefore reduce the risk of being exposed to unauthorised entry.
But security is not the only benefit. Because they spend less time in the open position, high-speed doors offer major benefits in maintaining climate control for temperature-sensitive areas, reducing draughts in the workplace, reducing the ingress of weather and/or dust and fumes, and keeping vermin and birdlife out.
The Efaflex range includes door blades manufactured from various materials, including extruded double walled aluminium, insulated panels, clear polycarbonate, punched ventilated aluminium, and flexible PVC, which is a less secure option that is commonly used for dust sealing. In all cases, the door blades are securely tracked within seals in the columns of the doors, and this provides improved security and sealing against vermin compared with a typical roller shutter door.
One critical design feature is that the door blade does not roll onto itself, but is tracked around a spiral design system. This results in very smooth and quiet operation, and results in very little wear. Efaflex holds the original patent for this design, which now also comes with an “oval spiral” option, and even a flat tracking design that is ideal for applications where there is low lintel space.
Each Efaflex high-speed door is driven by an electronic control system, combining a PLC with encoder positioning and frequency inverter drive control. This control system enables a wide range of programmable features so that the operation of the doors can be customised to each application.
Workplace safety is a paramount consideration, and so each door comes with a sophisticated sensor system as standard to ensure safe operation. A safety light curtain is synchronised to the door blade position, and is highly reactive to anything that intrudes into the closing space. Additional safety features include optional motion sensors that cover the immediate surrounds of the doorway, and flexible bottom rails for smaller doors with high pedestrian throughput.
A wide range of activation methods can be specified for each door, depending on the exact requirements of the application. These include pushbuttons, remote control, swipe cards, induction floor loops and various forms of active or passive motion sensors. The choice will depend on the nature and frequency of the expected traffic, the security level required and the level of climate and environmental control required. It is also important to consider the likely traffic in the vicinity of the door to avoid unnecessary opening of the door.
Being German designed and manufactured, you can be assured of the finest quality in high-speed door engineering. Built on four decades of experience and development, Efaflex is committed to a philosophy of in-house research and efficient outcomes, resulting in fast action doors built to a quality that you would expect from German engineering.
