This 20 ft blast freezer container – temperature range -40°F to 70°F, 460V/230V 3 phase provides ultra-fast freezing for food products, seafood, meat, and baked goods, preserving quality and extending shelf life . For example, you can rapidly freeze fresh seafood or meat products using the powerful cooling system that achieves -40°F. Therefore, this container significantly reduces ice crystal formation, preserving product texture and taste.
Why Choose a Blast Freezer Container?
Standard freezers chill products slowly, which can damage cell structure and reduce quality . In contrast, this blast freezer container rapidly pulls down product core temperatures, typically freezing items in hours rather than days . Consequently, you preserve product quality, reduce weight loss, and extend frozen shelf life . Moreover, the 20ft compact footprint allows placement on existing loading docks . Thus, you gain industrial freezing capability in a mobile, space-efficient package.
Key Features of This Blast Freezer Container
The wide temperature range and dual voltage capability make this blast freezer stand out. For instance, the temperature range spans from -40°F to 70°F, accommodating blast freezing, frozen storage, and chilled holding . Similarly, the ventilation system circulates cold air throughout the container to ensure product freezes quickly and evenly . Furthermore, the unit operates on either 460V or 230V 3-phase power, giving you flexibility in electrical connection . Finally, the CSC safety plate confirms structural integrity for intermodal shipping.
-40°F Blast Freezing Capability – Rapid Temperature Pull-Down
The -40°F capability sets this blast freezer apart from standard units. For example, the powerful refrigeration system rapidly reduces product core temperatures from ambient to fully frozen, typically achieving -40°F pulldown . Likewise, the advanced airflow design ensures even cold air distribution across all product surfaces . Furthermore, the rapid freezing process forms smaller ice crystals, which preserves product texture and reduces drip loss upon thawing . If you freeze seafood, meat, or ice cream, this blast freezing capability maintains premium quality.
460V/230V 3 Phase – Flexible Power Options
The dual voltage capability simplifies installation across different facility types. For example, the unit accepts either 460V 3-phase (common in industrial settings) or 230V 3-phase (found in smaller facilities) . Likewise, the standard 3-phase connection eliminates the need for expensive phase converters . Furthermore, the electrical panel includes appropriate breakers and disconnect for safe operation . If your facility has different voltage availability, this unit adapts to your existing supply.
Insulated Construction – Maintaining Extreme Temperatures
The high-density insulation ensures efficient operation at -40°F. First, the container features thick polyurethane foam insulation (typically 100-120mm) in walls, floor, and ceiling . Second, this insulation minimises heat leakage and reduces compressor runtime . Third, the insulated door with gasket seals prevents cold air escape during loading . Finally, the floor includes reinforced T-bar aluminium or stainless steel for easy cleaning and heavy loads . As a result, the unit maintains -40°F efficiently even with frequent door openings.
20ft Dimensions – Compact Freezing Capacity
The 20ft length provides substantial freezing capacity while fitting on most loading docks. For example, the internal length of approximately 19ft 4in accommodates up to 11 Euro pallets for blast freezing . Likewise, the internal width of approximately 7ft 8in-7ft 9in allows easy forklift access . If you need rapid freezing for smaller or medium-scale production, this 20ft blast freezer delivers the perfect capacity.
What’s Included
First, every unit includes the 20ft insulated reefer container with blast freezer specification. Second, the compressor unit provides rapid pulldown to -40°F with advanced controller and digital display. Third, we install an internal evaporator fan with automatic defrost cycle. Fourth, the electrical connection panel supports 460V or 230V 3-phase power with included circuit breaker. Finally, we include the CSC plate, data logger, and forklift pockets (4) for repositioning.
