Problem

When it comes to shopping, the key to success is a positive shopping experience. Customers have ever higher expectations in terms of supermarket conformity and equipment. In addition, new challenges such as the optimisation of energy efficiency and the commitment to strengthening the environment must be mastered. Refrigerated counters are among the most commonly used refrigeration appliances in food retail. The cooling of the counter, the organisation of the products and the locking system should work perfectly in order to create a positive shopping experience. The Italian company Cisaplast has set itself the task of developing a refrigerated counter that closes automatically. The components used in the locking system had to meet a wide variety of requirements.

Solution

Various igus components have proven themselves by meeting the appropriate requirements. The parts installed in the locking system of the refrigerated counter had to be durable, require no lubrication or maintenance and be lightweight. dryspin lead screw drives were used for opening and closing. These were driven with a drylin stepper motor. The lead screw nut is made from the high-performance polymer iglidur J and is therefore 100% lubrication-free and maintenance-free. The low temperature ranges do not pose a challenge for the material. A low friction of the lead screw drives and a quiet and vibration-free operation were further decisive factors. With the help of the dryspin lead screw drives and the matching stepper motor, a solution was found to make opening and closing the refrigerated counters as convenient as possible for customers.
