Heavy – Duty 20ft Blast Freezer Shipping Container
The 20ft Blast Freezer Container is an industrial – grade portable cold storage solution designed for rapid temperature pull – down and extreme low – temperature holding. Unlike standard refrigerated shipping containers (reefers) that simply maintain product temperatures, this unit features high – airflow evaporator fans and heavy – duty refrigeration compressors capable of bringing hot or room – temperature inventory down to – 40°F ( – 40°C) in record time.
Whether you operate in food processing, seafood export, pharmaceutical storage, or industrial chemical processing, this 20 – foot reefer container or commercial blast freezer UK provides reliable temperature control between – 40°F and +70°F ( – 40°C to +21°C).
Key Features & Operational Capabilities
Rapid Blast Freezing Technology: Powerful airflow systems lock in product freshness, prevent large ice crystal formation in food products, and meet strict HACCP compliance standards.
Dual – Voltage Versatility (460V / 230V 3 – Phase): Designed to integrate seamlessly into standard UK industrial 3 – phase power grids or generator power.
Superior Thermal Insulation: Polyurethane foam insulation embedded between high – grade Corten steel exterior walls and food – grade stainless steel interior lining minimizes thermal loss and reduces energy consumption.
Hygienic Interior Surface: Flat aluminum floor (or heavy – duty T – bar floor options) allows easy washdown, pallet loading, and sanitation routine maintenance.
Advanced Digital Temperature Controller: Easily set, monitor, and log internal storage conditions with integrated digital controls and alarm notifications.
Safety & Security: Equipped with interior panic escape hatches, internal LED lighting, and lockable double cargo doors for secure site operations.
