The challenge
Stacker cranes at -30 °C and shuttles at -25 °C. No exposure.
The frozen warehouse is expensive to build and dangerous for staff. The systems we implement for refrigerated logistics maximize every cubic meter of the automated cold depot while eliminating operator exposure to extreme cold.
"Each chamber door opening loses between 5% and 15% of the accumulated energy. Automating it cuts that cost by 30% to 40%, depending on how often doors are opened."
Why automate
Key benefits
Operation at -30°C
Stacker cranes certified down to -30 °C and shuttle robots down to -25 °C to operate in the frozen warehouse with no human presence.
Maximum density
Vertical storage that triples the capacity per square meter of the existing automated cold depot.
Fewer openings
Door-opening reduction of up to 90%, with energy savings of 30–40% depending on your current operation.
FIFO in cold
Automatic FIFO without the operator having to enter the chamber to check dates.
Before & after
Without automation
High energy cost of an underused frozen warehouse
Staff exposure to temperatures from -18°C to -30°C
Waste from frequent chamber openings to check stock
FIFO impossible to control manually in refrigerated logistics
High cost of building new chambers
With STOKA
Stacker cranes down to -30 °C and shuttle robots down to -25 °C in the automated cold depot, with no human presence
Vertical storage that triples the capacity of the existing frozen warehouse
Door opening reduction up to 90%
Automatic FIFO guaranteed by the WMS
Energy savings of 30–40% from less thermal exchange, depending on the baseline
Automation context
Warehouse automation in cold chain
Refrigerated logistics is one of the fastest-growing sectors in logistics automation. The automated frozen warehouse and the automated cold depot are the answer to the rising cost of labor in extreme cold.
The frozen ASRS we implement —the system for a frozen warehouse at -30 degrees— operates with no operators inside the chamber. The stacker cranes operate down to -30 °C and the shuttle robots down to -25 °C, with a special design: anti-condensation hermetic sealing, extreme-cold lubrication and internal electronics heating, keys to high-performance refrigerated logistics.

FAQ
Frequently asked questions about automation
What minimum temperature do the robots operate at in the frozen warehouse?
The stacker cranes are certified down to -30 °C and the shuttle robots down to -25 °C. They feature anti-condensation hermetic sealing, special lubricants and remote diagnosis.
What real energy savings can I expect in my automated cold depot?
Typical energy savings are 30% to 40%. The main source is reduced door openings: a manual warehouse requires 50-100 openings per shift, while the automated system works internally.
How much additional space do I gain by automating an existing frozen warehouse?
With automated vertical storage, you can triple the frozen warehouse capacity without building new facilities. The system operates in 900 mm aisles (vs. 3-4 meters for forklifts).
How do I eliminate staff exposure to extreme cold in the depot?
The automated cold depot operates autonomously inside the chamber. Operators work at ambient-temperature stations, where the goods reach the operator's station through an insulated pass-through.
