Our customer has been using punker fan wheels for the blower units of their technologically leading bakery systems and shop baking stations since the 1960s/1970s. After the customer consulted us in 2013 regarding the imbalances occurring in the blower units used in rack ovens and wagon ovens, punker has since then been responsible for the assembly of 700 blower units p.a. and the procurement of the required motors for the customer. This way, the customer was able to reduce their complaint costs significantly.
Our customer is a manufacturer of bakery systems, in-store baking stations and automation technology. Technologically, their systems are among the most sophisticated systems on the market today. The company group has subsidiaries on four continents where they employ a total of 700 people.
The company has been purchasing backward-curved fan wheels of the HLS70 series from punker since the 1960s / 1970s. Later, forward curved wheels of the TS / Fprime range were also added. The wheels are used in blowers for the various ovens.
In 2013, imbalances in the blowers in the field increased, which led to complaints from their customers. Due to limited capacities on the part of our customer and punker’s many years of experience in the development of air technology solutions for the food industry, the customer consulted us and asked for an analysis of the units.
The customer provided punker with all components of the blowers for a comprehensive analysis of the units. After a sampling phase at punker, the imbalances could be eliminated. In order to relieve the customer’s capacities, the production of the motor plate, the procurement of the motors and the assembly of the blower units is now carried out at punker.
punker supplies the customer with 12 different blower types in a total quantity of 700 units p.a. Further units/types will follow. Since punker took over the production and assembly in 2015, there have been no more complaints due to imbalances, the purchase of the blower units is cost-neutral for the customer.
