Spiral systems are available as a Spiral Freezer, Spiral Cooler, Spiral Chiller or Spiral Ambient System, available in site-built or compact factory-assembled format.

Unique individual quick freezing (IQF) technology ensures all products are chilled or frozen evenly, without excessive air speeds that could damage delicate products. Intelligent ‘guided airflow’ technology delivers circulated air, either vertically or horizontally.

MHM provides Spiral systems together with our UK-based technology partner, Starfrost.
