The broad portfolio of equipment & solutions for freezing and food processing.
We drive for more value for our customers.


Using cutting-edge technologies Make your factory smarter and more efficient




Self-stacking spiral freezer incorporate interlocking self-stacking belt, which tier by tier stacks on robust chain-ball driving system, completed with wire belt mesh and self-supporting side links, belt stack forms special ducting and enclosed freezing zone and works as circulation loop. Controlled cold air travels around food products while circulating through belt stack from the top down, high heat exchange minimizes freezing time and dehydration, achieves maximum throughput in minimal footprint.

The spiral components are delivered as pre-assembled modules for quicker installation whilst the refrigeration station can be delivered in complete piece. All electrical and piping connections between the two pieces of equipment are included and commissioned together.

to ensure reliable, consistent high capacity freezing.


Self-stacking belt, a variety of belt sizes and link heights available.

Belt widths available are 420, 660mm, 760mm, 930mm, 1070mm.

Chain-Ball Drive, ensure reliablibity of belt stack movement.
