How it works

The facility is tightly thermally insulated to limit heat ingress from the surroundings. An industrial refrigeration plant (commonly using ammonia or carbon dioxide as the refrigerant) removes heat and holds the set temperature in chilled and frozen zones. Sensors across the warehouse and in transport provide continuous temperature monitoring (data loggers, IoT systems), triggering alarms on deviations and documenting conditions for compliance. Goods move as an unbroken cold chain — from production through storage to transport in cold stores and refrigerated trailers (reefers). In modern facilities, low-temperature pallet storage and retrieval are handled by automated AS/RS systems, increasing storage density and reducing human work in the cold. The whole operation is energy-intensive, so energy management (including techniques such as peak shaving) is an important part of running it.

Problem solved

Perishable goods — fresh and frozen food, seafood, dairy, pharmaceuticals and vaccines — lose quality or become unsafe or ineffective when the temperature leaves the acceptable range. Temperature-controlled warehousing solves the problem of safe, long-term large-scale storage and distribution of such products, reducing food loss and protecting the integrity of medicines.

Components

Thermal insulationLimiting heat ingress from outside into temperature-controlled zones

Insulating layers of walls, roof, floor and doors that keep the low temperature stable at acceptable energy use.

Refrigeration plantRemoving heat and maintaining the target chilled or frozen temperature

Industrial refrigeration system, commonly using ammonia or carbon dioxide as the refrigerant, that drives the chilled and frozen zones.

Temperature monitoring (IoT)Continuous control, alarming and documentation of thermal conditions

Sensors, data loggers and IoT systems measuring temperature in the warehouse and in transport, detecting deviations and ensuring compliance (e.g. for pharmaceuticals).

Low-temperature automation (AS/RS)Automated storage and retrieval of goods at low temperatures

Computer-controlled AS/RS systems that store and retrieve pallets in sub-zero zones, increasing storage density and reducing human work in the cold.

Cold chain and transportMaintaining the temperature regime outside the facility, en route to the recipient

An uninterrupted sequence of refrigerated storage and transport (cold stores, refrigerated trailers, reefer containers) from producer to consumer.

Power supply and energy managementEnsuring power continuity and curbing high energy consumption

Powering the refrigeration plant and optimising the facility’s energy-intensive operation, including techniques such as peak shaving.

Evolution

1882
First effective cold store in the UK (St Katharine Docks, London)
Inflection point

Opening of the first effective cold store in London — it could hold 59,000 carcasses.

1908
First use of the term "cold chain"
1940
Patent for mobile mechanical refrigeration (Thermo King)

Frederick McKinley Jones patented a portable cooling unit for trucks carrying perishable food, enabling refrigerated transport.

1965
Emergence of AS/RS (automated storage and retrieval)

Automated storage and retrieval systems emerged in the 1960s, initially for heavy pallet loads; later extended to low-temperature zones.

2020
Ultra-low-temperature cold chain for mRNA vaccines (COVID-19)
Inflection point

The COVID-19 pandemic required a "colder chain" infrastructure at temperatures around −70 °C for vaccines such as Pfizer–BioNTech.
