- Typical cooling capacity
- For this class of equipment, cooling capacities commonly range from 100 kW to over 500 kW, depending on product load and desired temperature.
- Refrigerant type
- Units of this type commonly utilise ammonia (NH3) due to its high efficiency and environmental profile, though other refrigerants may be found.
- Evaporating temperature
- Typically, evaporating temperatures for spiral freezers are in the range of -35°C to -45°C to achieve rapid freezing.
- Belt width
- Commonly, belt widths for industrial spiral freezers range from 600 mm to 1500 mm, influencing throughput.
- Product clearance (GAP)
- Product gaps are typically between 50 mm and 100 mm, dictating the maximum height of products that can be processed.
- Footprint
- Spiral freezers require a significant footprint; dimensions commonly vary based on belt length and number of tiers, but will always be substantial.
- Power supply
- Typically requires a three-phase industrial power supply, commonly 400V, 50Hz, with significant installed power for compressors and motors.
