The design of the ALFA machines seeks a compromise between the volume and the number of pieces of ice. The result is a cube with straight edges that increases productivity (more cubes per cycle) and optimizes storage. ALFA machines achieve, therefore, the best relationship between production and cost. The elastic shower system, patented by ITV, prevents limescale problems. The frontal in-out system guarantees perfect ventilation. In order to accurately control the production, separate thermostats help regulate both the production time and the amount of ice stored.
