To achieve this, extended, 1700mm deep dock shelters have been fabricated so that the inflatable head creates a seal on the rear of the trailer at the front of the aerodynamic slope. This simple design prevents rainwater from running into the building and minimises a potential slip hazard. Another design element that adds to the efficiency of this site, ensures that the 32 Iso Speed Cold doors fitted to the internal part of the freezer loading bays with a secondary external door to close in front of the dock leveller, preventing this acting as a thermal bridge. All the dock levellers on this site are fitted with telescopic lips for this purpose; however this also adds flexibility to the range of trailer heights that can be accommodated. Interlocked doors that create three “indoor” enclosed canopy level access unloading area for trailers are a new design feature. Three Hörmann HS7030 high speed spiral door lead from the chilled area whilst two insulated SPU sectional doors are fitted to the exterior. The interlock prevents either set of doors being open at the same time, minimising thermal losses. Energy efficiency extends to the use of LED dock lights that have the added benefit of providing a better spread of light into trailers being unloaded. Additionally PIR sensors are fitted to ensure these lights are only activated when needed, another energy saving measure. While a number of features and design elements add to the overall efficiency of the site and reduce energy consumption, safety improvements have also been made. As with other Asda sites, each loading bay is equipped with wheel locks and a driver button that activates the loading door and bay controls, only when the driver confirms the vehicle is parked safely and securely in the correct position. This safety feature has been pioneered by Asda and Hörmann. Originally, the Asda control sequence was connected to the loading bay panel on site, however, the complete integrated package is now factory manufactured by Hörmann and is available as a standard option for all projects. In order to ensure that the benefits of the new designs are maximised, Hörmann is also contracted by Asda to supply a service and maintenance package. By keeping the equipment in prime condition, reliability, safety and longevity are improved, therefore adding to the savings by minimising downtime and reducing whole life costs. By providing the service cover Hörmann is also adding to its own extensive knowledge and can feed data back to its new product development teams to help shape the designs of the future. ROLLMATIC ROLLING GRILLE FROM HÖRMANN The lightweight and compact design of Hörmann’s new RollMatic Rolling Grille makes it not only good value, but also the ideal solution for shop grilles in confined spaces. The RollMatic, with retainers on either side of the curtain reliably supports the door, and its break-in-resistant fastening offers heightened security. The variety of locking options on offer further maximises security. A lockable bottom profile with a cylinder lock for both interior and exterior locking is available, alternatively the grille can use a shootbolt. Both easy to fit and easy to use, the RollMatic can open manually with a pull chain or a cord, or automatically using an operator. The operator is neatly hidden from view as it is fully enclosed within the barrel cover to maintain the Rolling Grille’s sleek appearance and compact design. Proven tension spring technology ensures that safety is not compromised and double cabling provides additional protection when the operator is in use. This technology also enhances the ease of use, adding to the smooth operation, whether manual or automatic. The RollMatic Rolling Grille is available in 2 curtain variants both with a superior finish. The HGL, in lightweight and compact aluminium, makes the grille economise space and is therefore particularly suitable for use in shopping arcades. The other option is the HG 75 with extruded aluminium profiles and is available with either a straight or an offset arrangement.
