The alco-Spiral-Freezer ASK


The alco ASK spiral cooler/freezer is used for the cooling and shock freezing of food products. The spiral belt conveyor design allows a considerable process length to be generated while the space requirement is small. In addition to standard compact freezers of the Eco and Pro series, special-design freezers of all sizes are available. The compact freezers are distinguished by their transportation-friendly design, low installation times and excellent price/performance ratio, while the special-design freezers leave nothing to be desired in terms of their adaptation to the product and the production environment. Every special-design freezer is calculated according to the customer-specific requirements and specially designed so as to achieve maximum energy efficiency and the optimal application for the product.

For your application we offer you, based on our standard design, machines of various sizes as well as different additional options and add-on equipment. Due to the flexible combination options, we can configure the perfect solution for you. Should your optimal solution, however, not be achievable in this way, we would be glad to develop it together with you.
