Smart warehouse storage design
In the frozen food and beverage sector, you aren’t just paying for square footage; you are paying to refrigerate oxygen. Traditional “block stacking” creates honeycombing—empty pockets of -20°C air that drain your OpEx. Our smart design philosophy stops this waste by converting horizontal sprawl into vertical density, ensuring strict FIFO compliance for perishables without a single forklift driver entering the freezer.
The Vertical Economics of Cold Storage
For facility managers in the cold chain, the primary design constraint is the cost of the refrigerated envelope. A standard warehouse requires a massive roof and foundation footprint to store 10,000 pallets. By shifting to a Rack Clad Warehouse design, we treat the racking system not just as equipment, but as the structural skeleton of the building itself.
Using Q355 high-strength steel, starack systems can reach heights of 40 meters (131 feet). This reduces the roof surface area—the primary source of thermal loss—by up to 70% compared to a conventional flat warehouse. The result is a drastic reduction in the refrigeration load. You are no longer cooling a sprawling cavern; you are cooling a compact, high-density cube.

Solving the Honeycombing Effect with Depth
In standard selective racking, aisle space consumes nearly 60% of your floor plan. For beverage distribution or raw material storage (like frozen concentrate or flour), this is inefficient. The solution lies in sacrificing immediate selectivity for extreme density using a multi-deep Automated Pallet Warehouse configuration.
By utilizing a “Satellite Shuttle” or double-deep telescopic forks, we can store pallets 4 to 10 deep. This effectively eliminates the aisles between racks. For a producer running large batches of identical SKUs, this compacts the storage footprint significantly. The starack-Shuttle system is specifically engineered for this, ensuring that even in a LIFO (Last-In, First-Out) or batch FIFO environment, the volume of air being cooled per pallet stored is minimized.

Energy Regeneration and Structural Rigidity
Smart design extends to the kinetic management of the machine. In a 30-meter high warehouse, a lowering pallet generates significant gravitational potential energy. starack stacker cranes are equipped with regenerative braking units. As the carriage descends, the motor acts as a generator, feeding energy back into the DC bus to power the horizontal travel motors. This cycle reduces overall energy consumption by 20-30%, a critical saving for high-turnover distribution centers.
Furthermore, precision at height is non-negotiable. Using a fully bolted structure with Q355 steel, rather than on-site welding, provides superior resistance to dynamic fatigue. This rigidity ensures that even at 40 meters up, the mast oscillation is controlled within millimeters, preventing “nuisance stops” where sensors falsely detect a collision due to sway.

Comparison: Flat Warehouse vs. Smart Design
| Operational Metric | Traditional Flat Cold Storage | starack AS/RS Smart Design |
|---|---|---|
| Land Footprint (10k Pallets) | Approx. 10,000 sqm | Approx. 2,500 sqm (Save 75%) |
| Energy Cost | High volume of air to cool; frequent door openings. | Minimized volume; Regenerative braking saves ~25%. |
| Stock Rotation (FIFO) | Dependent on manual discipline; high risk of expiry. | Software-enforced absolute FIFO/FEFO by WMS. |
| seguridad | Forklifts operating in -25°C visibility mist. | Zero human entry into the freezer zone. |
Frequently Asked Questions
-
Can this system handle blast freezing temperatures?
Yes. Our Automated Pallet Warehouse components, including motors and sensors, are rated for environments as low as -30°C (-22°F). We utilize specific low-temperature lubricants and heated control cabinets where necessary. -
How does the system handle pallet overhang or damaged pallets?
We implement a rigorous profile gauge (contour check) at the induction station. If a pallet has overhang >50mm or broken boards, it is automatically rejected before entering the high bay, preventing jams at altitude. -
What is the typical ROI period for a cold storage AS/RS?
Due to the high cost of land and energy in cold chain logistics, the ROI is typically faster than ambient warehouses, often ranging between 3 to 4 years depending on local labor and electricity rates. -
Is the Rack Clad structure certified for seismic zones?
Absolutely. The Q355 steel structure is engineered with specific seismic calculations. Being a “bolted structure” rather than welded allows for better energy dissipation during seismic events compared to rigid welded frames. -
Can we integrate this with our existing ERP (SAP/Oracle)?
Yes. The starack WMS acts as the execution arm. It interfaces directly with your ERP to receive “Goods In” and “Goods Out” orders, returning real-time inventory data without manual scanning.
