Cold Storage ASRS Upgrade Case Study: 7,000 Pallet Positions at -25°C Automated Warehouse

Cold storage facilities face unique operational challenges compared with conventional warehouses. Low-temperature environments increase labor costs, reduce worker productivity, and create significant pressure on warehouse operators to maximize storage efficiency while maintaining product quality.

As labor shortages and cold chain logistics demands continue to grow, many companies are looking for ways to upgrade traditional cold warehouses into highly automated storage facilities.

This project demonstrates how a conventional cold storage warehouse was transformed into a fully automated ASRS (Automated Storage and Retrieval System), significantly improving storage density, operational efficiency, and inventory management while reducing human exposure to extreme temperatures.

This cold chain automation project covers multiple temperature zones ranging from:

-25°C to +7°C

The facility serves high-volume cold storage and distribution operations requiring reliable and efficient pallet handling.

Key Project Specifications

• 7,000 pallet storage positions
• 21-meter-high ASRS warehouse
• High-speed stacker crane system
• 160 pallets per hour throughput
• Automated roller conveyor network
• AGV pallet transportation system
• Automatic empty pallet supply
• Online order picking system
• Automatic weighing and inspection
• Automatic packaging integration

The result is a fully automated cold storage facility capable of handling inbound, storage, picking, and outbound operations with minimal manual intervention.

This cold storage ASRS upgrade project demonstrates how traditional refrigerated warehouses can be transformed into highly efficient automated logistics facilities.

By integrating a 21-meter ASRS warehouse, stacker cranes, conveyor systems, AGVs, automated picking, and intelligent warehouse management software, the facility achieves higher storage density, faster throughput, improved inventory control, and significantly reduced labor requirements.

For companies operating in frozen food, pharmaceutical, and cold chain logistics industries, warehouse automation provides a practical path toward greater efficiency, scalability, and long-term competitiveness.

Many cold chain operators face common challenges:

• High labor costs in low-temperature environments
• Difficult recruitment and worker retention
• Limited storage capacity
• Slow pallet handling efficiency
• Inventory inaccuracies
• Rising energy costs

Operating forklifts and manual warehouse processes in temperatures as low as -25°C creates both operational and safety challenges.

Warehouse automation provides a long-term solution by reducing manual intervention while maximizing storage utilization.

The core of the project is a high-density ASRS warehouse equipped with stacker cranes operating inside a 21-meter-high storage structure.

Compared with conventional cold warehouses, the ASRS system offers:

• Higher storage density
• Faster pallet handling
• Improved inventory accuracy
• Reduced forklift traffic
• Lower operating costs

The system maximizes cubic storage utilization, allowing operators to store significantly more inventory within the same warehouse footprint.

Incoming pallets arrive through receiving stations connected to the conveyor system.

The process includes:

Pallet Identification

Products are automatically identified using barcode or warehouse management systems.

Automatic Inspection

Weight and dimensional checks verify product information before storage.

Conveyor Transportation

Roller conveyors transport pallets directly to the ASRS system.

Automated Storage

Stacker cranes automatically place pallets into assigned storage locations based on inventory management rules.

No manual forklift operation is required.

To further reduce labor dependency, the project integrates AGV pallet transportation vehicles.

The AGVs perform tasks such as:

• Pallet transfer
• Material delivery
• Buffer area transportation
• Production line connection

This creates a highly automated logistics flow between warehouse and production operations.

Benefits include:

• Reduced labor requirements
• Improved operational safety
• Flexible transportation routes
• Continuous operation capability

The warehouse includes an intelligent online picking system designed to support high-volume order fulfillment.

When orders are generated:

Inventory Retrieval

The warehouse management system automatically generates retrieval commands.

Stacker Crane Operation

Required pallets are automatically retrieved from storage locations.

Conveyor Delivery

Products move through conveyor systems toward dispatch areas.

Automatic Weighing and Inspection

Quality checks are completed before shipment.

Packaging and Dispatch

Products are prepared for transportation with minimal manual handling.

The entire process significantly improves order fulfillment efficiency while maintaining product traceability.

The upgraded facility achieves:

7,000 Pallet Capacity

High-density storage dramatically increases warehouse utilization.

160 Pallets per Hour Throughput

Fast inbound and outbound operations support high-volume logistics requirements.

Reduced Labor Exposure

Workers spend less time inside extreme cold environments.

Improved Inventory Accuracy

Automated tracking reduces inventory discrepancies.

Lower Operating Costs

Automation reduces labor and handling expenses over the long term.

Cold storage automation projects require specialized engineering considerations.

Key design factors include:

• Low-temperature equipment selection
• Frost prevention strategies
• Conveyor reliability
• Cold-resistant sensors
• AGV performance in refrigerated environments
• Energy efficiency optimization

Successful implementation depends on balancing warehouse throughput, storage density, and environmental requirements.

For procurement teams evaluating cold storage automation projects, important considerations include:

• Storage capacity requirements
• Throughput targets
• Temperature range
• Product characteristics
• Warehouse dimensions
• Future expansion plans
• Software integration requirements

Choosing the right ASRS configuration can significantly impact long-term operating costs and return on investment.

Cold storage automation delivers benefits beyond labor savings.

Key business advantages include:

• Increased warehouse capacity
• Improved order fulfillment speed
• Lower labor dependency
• Better inventory control
• Enhanced food safety compliance
• Improved operational scalability

As labor shortages continue to impact cold chain operations worldwide, automated cold storage facilities are becoming increasingly attractive investments.

Frozen Food Manufacturers

High-volume frozen product storage and distribution.

Cold Chain Logistics Providers

Efficient handling of temperature-sensitive products.

Pharmaceutical Warehouses

Controlled storage environments for medicines and healthcare products.

Food Processing Plants

Automated storage for raw materials and finished goods.

Distribution Centers

High-throughput cold chain fulfillment operations.

The future of cold storage facilities includes:

• Fully automated ASRS warehouses
• AI-driven inventory optimization
• AGV and AMR integration
• Robotics-assisted picking
• Digital warehouse twins
• Energy-efficient refrigeration systems

Automation will continue to play a critical role in improving cold chain efficiency while reducing operating costs.
