ENERGY SAVING AND SAFETY IN LOGISTICS WAREHOUSES FOR VERY LOW TEMPERATURES

 

When considering the management of a refrigerated warehouse for the conservation of fresh or frozen foods, the biggest challenges concern the use of insulating materials, especially in cases where external temperatures can exceed 50°C. The commercial vehicles used in cold chain logistics often have hinged rear doors which do not allow the vehicle itself to dock right up against the loading bay, resulting in thermal losses caused by having to open the doors at a distance from the loading bay. Insulating logistics warehouses dedicated to the storage of products at very low temperatures by insulating the load bays offers significant energy savings and reduces refrigeration costs.

COMBINING SAFETY WITH ENERGY SAVINGS

Campisa has many years of consolidated experience in the production of cold chain installations with insulating solutions capable of catering for temperature differences between the exterior environment and the interior of the load bay of approximately 90°C in the case of frozen foods and 50°C in the case of fresh foods (with storage temperatures between 0 and +5°C). Effectively insulated work spaces, energy savings and safety systems preventing risks for the operator are the three indispensable elements distinguishing all Campisa solutions.

A NEW CAMPISA PROJECT MAKES A BIG IMPACT IN THE MIDDLE EAST

Through its regional distributor, Campisa has installed 78 recessed loading bays in a large new logistics warehouse in the Middle East. With an exclusive highly insulating mechanical dock-shelter and telescoping dock levellers, the recessed system (patented by Campisa) offers extraordinary thermal performance.

The sectional doors, which are fully 80 mm thick and fitted with a window with three insulating air gaps and patented trapezoid cross-section seals between the doors themselves and the dock leveller pit, keep the entire dock leveller within the interior of the building when the latter is retracted. The Fidelity® hydraulic door lifting system (delivered European Patent) does away with the need for counterbalance springs and, as the result, of the regular maintenance they require, and ensures a reliable seal at the bottom of the door. With no counterbalance springs, this system is not susceptible to spring decalibration, a problem which very often prevents the balanced door from sealing correctly at the bottom, leaving a gap higher than 5 cm along the entire width of the door.

To minimise thermal losses during the docking procedure, the door remains shut throughout the process and can only be opened once the vehicle has effectively docked and the mechanical seal has closed onto the van, insulating the interior atmosphere against contact with the exterior environment. Once the vehicle is docked – which is facilitated by ground level wheel guides to assist reversing – and the seal is fixed in place onto the vehicle, the sectional door opens and, once open, enables to open the sectional door, then (at open door) enables operation the dock leveller, which is then extended to the load bed of the truck.

The load bay docking process is guided by a traffic light signal system which ensures total safety and effective thermal insulation efficiency.An interior and an exterior traffic light signal (connected to the wheel retainer chocks) notify the operators working inside (warehouse personnel) and outside (drivers) the building when a vehicle is docked, so that they can then close the seal onto the vehicle, open the sectional door, extend the dock leveller and start loading. As well as ensuring operator safety, this solution also offers huge energy savings.

 

To further increase operator safety and prevent the risk of damage to equipment, the patented Fidelity® hydraulic door lift system allows the installation of the “SafeGuard” device on the bottom panel of the sectional door, which protects the door against impact from fork lift trucks and prevents the risk of a fork lift truck breaking through the sectional door itself and falling from the dock into the yard.

Increasing numbers of companies are choosing these environmentally friendly and safe installations as they offer extraordinary energy savings and safety.
