In the introduction of this paper there is a description of cooling and dispensing units which are nowadays most common in the market. It describes the way they work, and different device models on the market. This paper includes the calculation of the cooling units according to a specific customer requirement and shows the specific requirements that the cooling units must satisfy. Calculation of cooling units is based on the dispensing capacity, according to the calculation there are selected appropriate components for the required cooling conditions. This paper is focused on the manufacturing process and control during production of cooling unit, therefore, in the paper are described in details the production, the way and the type of control during the production of cooling units. The description of the production process is shown through four main processes: production process of sheet metal, tube bending, production of cooling container and mounting units. The stages of making are accompanied by pictures, description of the procedure, the machines used during the making and description of control activities, from the beginning until the preparing for delivery to the customer.The paper also includes an experimental part in which it is being implemented the laboratory testing of the cooling unit, which proves that the unit meets the dispensing capacity. The laboratory testing is carried out according to the norm ANSI/ASHRAE 32.2-1997 in Oprema d.d. company.
