- Typical capacity
- Throughput varies significantly based on product type, temperature, and dwell time, but units of this class are designed for continuous high-volume freezing.
- Power supply
- Typically requires a three-phase industrial electrical supply, commonly 400V/50Hz in the UK, with specific amperage requirements for the compressor and motors.
- Refrigeration system
- Units often integrate or are supplied with a dedicated refrigeration plant, commonly using refrigerants like Freon 507 or similar HFCs, or sometimes ammonia for larger industrial applications.
- Belt width
- Commonly features belt widths ranging from 400mm to over 1000mm, influencing product throughput and size compatibility.
- Number of tiers
- Spiral freezers typically have multiple tiers (e.g., 10 to 20), maximising freezing capacity within a compact footprint.
- Product gap
- The vertical product gap between tiers commonly ranges from 50mm to 150mm, determining the maximum height of products that can be processed.
- Footprint
- While offering high capacity, spiral freezers are designed to be space-efficient, with a relatively compact footprint for their output, often requiring a dedicated area for installation.
