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.


If a walk-in coolroom is an essential modular construct, then the installed panel system is the armoured envelope that defines the thermal characteristics of this insulated cooling space. The installation panel system in question is designed to assemble readily, seal reliably, and present a unified thermal barrier. Built from advanced materials, the panels employ smart coupling technology, such as the renowned cam-lock coupling system.

Installation Panel Systems: Locking Mechanisms 

Before advancing any further, just how do the modular panels create that steadfast seal? Basically, there are special locking systems that are built specifically for the job. They’re typically attached to the panels as toughened plastic blocks, with heavy gauge hooks and reinforced pins taking on the role of the dependable fasteners. They come together when the panels are aligned, lock in place, and use their heavy gauge stainless steel outlines to secure the assembling chambers’ many wall panels. Used in concert with a special angled key, the tool and wall locking mechanisms guarantee fast and secure modular assembly.

Cool and Professional Assembly Skills 

Whether the locking system requires a cam-wrench or a traditional screwdriver, the work still requires an expert construction service, an engineer and technical group who can build this framework with confidence. Perhaps we should be talking about competence as well as confidence, for the structurally stable module is hardly finished. Next, there are commodities fittings and plumbed pipes, plus their drainage channels to install. There’s a ceiling coupled to the walls now, and there’s an insulated floor. Next, the composite wall panels are installed. These panels are laminated with an extruded polymer, then they’re glued to durable metal skins. The installation panel system has taken on a layered architecture, with the modular panel system on the outside, the composite, metal-skinned insulation panels on the inside, and the open area chamber right in the centre. Inside that core, a few light fixtures, wire-mesh shelves, and an energy-efficient refrigeration unit complete the structure.

Tongue-in-groove panels, cam locking mechanisms, and gaskets form the structural backbone of a modular coolroom. Next, a layer of temperature resistant caulking increases the unit’s R-factor and produces an optimally sealed cooling space. When this sealed space is standing tall, composite insulation panels are fixed inside the enclosure while the door seal and electronic control system receive attention. Finally, the refrigeration housing and all of its fitting are installed, tested, and placed in an inactive but ready stage until the furnishings are carried inside. Properly inspected, the coolroom is ready to produce its frosty atmosphere.
