Tunnel and Spiral Footprint Comparison
Enter a throughput. The comparison returns both floor areas, both refrigeration duties and the difference between them, from the published dimensions of our ST-SDS tunnel and ST-LXS spiral ranges. It exists because the claim that a spiral always saves floor space is not always true at the capacity most food processors actually buy.
Your throughput
Target capacity, kg/h
Ceiling height available, m
At that capacity
Enter a capacity and press the button.
Published pairs exist at 300, 500 and 1000 kg/h, so a figure between two pairs is answered on the next pair up — that is the machine you would be quoted. Areas are machine envelopes, not installation clearance. Other builders arrange machines differently, so the crossover on your shortlist may differ from ours; this compares our two ranges, not the market.
For related planning details, see the Tunnel IQF freezer.
