The demands on modern chest freezers for commercial use in supermarkets and catering establishments are high. They are expected to be energy-efficient, powerful, sturdy and attractive – and to have the lowest possible power consumption at the same time. On behalf of Liebherr, Fill has now developed a manufacturing facility consisting of six assembly stations that enables an innovative production method. The outer shell of the freezers is sprayed with several layers of functionally different polyurethane systems in a continuous pass. Various fillers can be selectively and flexibly adapted to the specific requirements. The metering systems are controlled by the new Siemens S7/1500 generation. The ´flextrac´ system allows the overall cycle time to be varied as required. The Liebherr-Hausgeräte Lienz GmbH has more than 1300 employees at its works in East Tirol and produces around 470,000 appliances per year. The company was awarded the Regional Award for Innovation 2014 by the province of Tirol for the new supermarket chest freezers produced on the Fill manufacturing facility.
