It was neither an engineer nor a physical measurand that impressed the discounter giant ALDI in its decision making per tube heater, it was spinach. Because this green leafy vegetable is one of the most sensitive vegetables to climatic influences during storage.
Founded in 1994 in the USA, the mail order company has since risen to become the world’s largest Internet retailer. Originally, Amazon concentrated on selling books, but now there is almost nothing that Amazon cannot supply.
The largest Polish steelworks with approx. 4,000 employees and a capacity of 5 million tons per year is located in Katowice. The plant has three blast furnaces, two rolling mills, three continuous steel foundries and its own power plant.
As with many refurbishment projects, the first realisation was that the existing heating system for the production halls and warehouses was too expensive and that it did not meet the requirements for comfort and heating performance anymore.
The constant increase in energy costs and the ever more frequent maintenance measures made a renovation of the heating system unavoidable.
The BMW Group has set itself the goal of continuously increasing production while maintaining the same level of energy consumption. The so-called energy sustainability index regards the heating system as an essential component of this overall economic efficiency.
Foundries are characterised by unusual spatial conditions, whether new or old. While the casting furnaces produces enormous heat, blowers suck off the polluted air in very large quantities. This is about 30,000 m³/h per hall area.
The 2.000 m² should be kept at max. 25°C in summer, in winter the hall should be warmed up to 18°C with the same system. The conversion of the heating and cooling system had to be carried out during running operations.
Daimler AG has built a new logistics center in Speyer for around 90 million euros, the so-called Consolidation Center. It is the largest building complex in Germany. The building measures more than 1 kilometer on the long side.
The efficient helmet floodlights and dark floodlights are used again and again in Porsche workshops and branches, for example in Würzburg.
The year round requirements for the new heating and cooling system require 18 ° C to 25 ° C and a relative humidity of less than 60%. In addition to the heating system already installed, a further system should ensure cooling in the summer as well as maintaining the humidity.
The original boiler system in the production was replaced by an efficient heating system with tube heaters by Schwank. The success: 40% savings.
