Purposes of Bollard Traffic Door Systems in Freezers and Coolrooms24 July 2017
Traffic door systems are installed in coolrooms when access problems become unavoidable. We’re talking about the passage bottlenecks that exist between the threshold of a large-scale freezer and the narrow aisles that contain spoilable commodities. Pallet jacks and wheeled trolleys zip between the evenly spaced bollards guarding those thresholds, but larger vehicles are obstructed. Designed to segregate pedestrians and lifting vehicles, the system exists as a best practice security solution.
Best Practice Entryway Screening
Commercially viable coolrooms and freezers use heavier equipment profiles. Even up on the refrigeration unit, there’s a two or three fan housing with wider bore cooling pipes working to chill the large area. Split into numerous work zones, the squared portals are equipped with transparent PVC curtains and a traffic door system. That latter fixture is installed as a series of aligned bollards. Spaced just-so, the security posts allow pedestrians and vehicles of a predetermined width to pass freely, but larger vehicles are stopped in their rubber tracks.
Perimeter Defense Guards
Once the door bollards have been installed, their measured presence screens the different work areas. Meanwhile, around the wide floor space of the coolroom, there’s a legion of additional bollards. Every security post is situated at a strategic turning place or sensitive load bearing wall. They’re possibly padded and definitely reinforced. Installed in front of narrow wall pillars and blind access doorways, the waist-high stanchions stop unwary workers, and the building’s structure, from a nasty encounter with a forklift truck.
Cold Storage Protection Systems
At this point, we’re talking about pedestrian traffic, which is as it should be because these stout posts are designed to preserve human life. However, there’s more to a bollard traffic door system than its screening credentials. The posts also act as the leading edge of a mechanical cage, a frame that prevents cold storage room bay doors from physical damage. Fastened around the larger entryway, the security posts act as a distancing tool, a barrier that stops door damage when heavy vehicles aren’t fully under the control of their operator.
Importantly, security problems are created by a large door rip. The weather penetrates a regular storage area, and the contained products are put at risk. In freezers and coolrooms, however, that rip or broken door seal equals an energy imbalance. The self-contained arctic environment is no longer maintainable, or, if it is, then huge amounts of energy are wasted to keep the large space cool. Bollard-lined traffic door systems eliminate that disastrous possibility. Furthermore, perhaps with the aid of a reflective strip, the bollards guide traffic while they screen the work areas from heavy vehicle penetration.
