Each aisle used for display in the cooling sector produced a certain amount of water and this water was discharged from the cabinet with the help of a water drain. Unlike the water drains used in old-fashioned systems, the WDS product was completely redesigned considering the needs of the industry. With the new design, water drain breaks during shipment are prevented and chronic problems are prevented. In addition, with its modular structure, parts can be replaced in case of damage. Thanks to its gradual structure, it prevents 100% of possible water leaks. Hygiene and odor problems are not experienced together with the structure that enables water drainage to occur without any problems.
