Industrial Freezers That Power Global Food Production
Three proven platforms. Each engineered, manufactured, and tested in one integrated 640,000 m² campus. Each backed by a 200-person global installation team.
Spiral Oven
Continuous spiral cooking and baking. Multi-zone temperature control, steam injection, and precise airflow. For breaded products, baked goods, roasted items.
Fryer
Continuous deep-frying for coated products, par-fried snacks, and prepared foods. Precise oil temperature control, sediment removal, and filtration system.
Manufacturing
Built in One Location
Steel fabrication, refrigeration assembly, PU foaming, electrical panel building, and finished-system testing — five shops, one quality system.
