Industrial cold storage is a critical pillar for several major sectors, including dairy, meat processing, seafood, fresh produce, and agriculture. For businesses across the region, maintaining the integrity of the cold chain is a non-negotiable requirement.
However, the harsh conditions of sub-zero environments present significant operational hurdles that traditional manual handling often fails to address efficiently.
To overcome these challenges, we have introduced a new generation of ASRS cold storage technology designed specifically to thrive where standard equipment falters.
Low Temperature Storage System Challenges
Operating a warehouse at -20°C or lower introduces a unique set of physical and mechanical stressors. These stressors may compromise long-term productivity and safety in cold rooms.
Equipment Impact
In freezer environments, standard batteries suffer rapid degradation, losing significant capacity and runtime. Structural materials such as steel and plastics can become brittle, increasing the risk of stress fractures under load. Furthermore, electronic sensors are prone to malfunction or “drift” due to the extreme cold, leading to system inaccuracies.
Condensation and Ice
The movement of goods and the opening of freezer doors introduce ambient air, creating condensation. When this moisture freezes, ice builds up on the rails, causing pallet misalignment. This disrupts the travel of shuttles and conveyors, severely reducing traction and positioning accuracy, which leads to frequent system halts.
Maintenance and Service
Freezer environments pose elevated safety risks for personnel. Maintenance tasks that take minutes in ambient conditions require significant time and specialised gear in the cold, leading to longer downtime per service event and increased operational costs.
Dexion’s MDS ASRS 4-Way Shuttle for Cold Storage Warehouses
Dexion has developed the MDS ASRS four-way pallet shuttle as an evolution of the HDS Shuttle— a high-density 2-way system with a long operational heritage in refrigerated environments. Built on a foundation of over 15 years of expertise, Dexion has successfully deployed more than 200 MDS ASRS units in freezer environments across the Asia Pacific.
These systems are engineered for reliable coldroom performance at -20°C operating temperatures, making them suitable for storing dairy, meats, seafood, fresh produce, and wine. Our solution is fully automated 24/7, integrating AI and machine learning with zero-code shuttle scaling to allow for flexible throughput adjustments.
Furthermore, the system remains fully compatible with existing Warehouse Management Systems (WMS) and is backed by established local service, parts, and maintenance network to ensure your cold storage warehouse solutions remain operational.
How the MDS ASRS 4-Way Shuttle Thrives in Freezer Environments
Success in cold storage requires more than just standard cold storage warehouse technology; it requires engineering that accounts for thermal cycling and moisture.
Equipment Resilience
We utilise cold-rated components and materials specifically selected for their performance in sub-zero temperatures. Our control systems are designed to remain stable during thermal cycling, housed within enclosed, insulated system designs. To further reduce downtime, we provide remote predictive and preventative maintenance support.
Rail and Traction Reliability
The four-way shuttle system features a wheel and rail interface thoroughly tested for low-temperature, low-friction conditions. This ensures stable traction even when faced with frost or condensation. We do not rely on untested materials or contact surfaces that might fail when the temperature drops.
Sensor Reliability
Our sensors maintain high levels of accuracy despite temperature differentials. They are engineered to perform reliably during the “fog” often caused by door cycles and are resistant to moisture ingress, ensuring the ASRS shuttle system maintains its positioning without manual intervention.
Energy Efficient Equipment Design
Sustainability is core to Dexion’s design. The MDS shuttle automatically powers off when not in use to conserve energy. Our IP65-rated batteries are built for freezer demands and are programmed for opportunistic charging, allowing for cost-efficient energy consumption during off-peak periods.
Conclusion
Future-proofing your facility is essential to conserve resources and maximise throughput in an increasingly competitive market. Transitioning to advanced automation ensures that your cold chain remains unbroken and efficient. Whether you are operating out of primary distribution hubs in Australia or managing regional logistics, our team is ready to assist.
