Efaflex, represented in Australia by Aircom , produces the ES elastic folding door, a low-cost system for difficult working environments.
The door is generally used to insulate the insides of plants against draughts, dust and noise, lowering energy costs while still allowing forklift traffic. It folds open horizontally and is constructed of connected, flexible PVC sheets. The door leafs are fully transparent and can be up to 12mm thick, with generous overlaps and cord connectors between the gaps. In the event of a collision these connectors are designed to snap, protecting the rest of the door from damage. This, combined with the flexibility of the panels, makes the door very resistant to impact damage. A gentle vehicle collision will often leave the drive parts undamaged. The drive elements are also protected against sprayed water and dust and the PVC panels are resistant to ageing and weather, providing along working life. Because the doors hang no guide rails need to be installed in the floor.
Strong guide rails and smooth running carriages allow the door to be easily opened manually. Electric and pneumatic drive units are available and both can open or close the door at up to 2m/s. Where pneumatic drives are used the door wings can be controlled separately, allowing pedestrians to only half-open the door and vehicles to completely open it. This flexibility allows energy costs to be reduced. The door comes fitted with an automatic control unit as standard, but this can be combined with a range of activation methods.
Supporting steel elements come galvanised as standard but are also available painted or can be replaced with stainless steel. A deep freeze version of the door is also available for applications where the door must operate at a constant temperature of -28°C.
The door can be supplied in standard building sizes up to 8m wide and 6m high.
