By combining state-of-the-art technology with Danfoss’ long-standing knowledge of process optimisation within refrigeration, heating, ventilation and speed control, Danfoss Solutions A/S has managed to reduce a production company’s energy consumption by 10-15 per cent.
Danfoss Solutions A/S highly prioritises employee involvement in its energy savings activities. When all of the company’s employees are more conscious of their conduct and its impact on the company’s energy consumption, the energy consumption can be reduced by several additional percentages.
Danfoss Solutions has carried out a range of projects for companies such as Carlsberg, Tulip and Coca-Cola. At Carlsberg’s brewery in Fredericia, they managed to save five million DKK on the energy bill in just 2.5 years (from August 2003 to March 2006). One of the major gains with regards to electricity was obtained by installing frequency converters on engines, pumps and compressed air compressors which regulated the speed according to the consumption.
Another area where it was possible to save money was in the process which transforms CO2 from liquid to gas. The brewery used to use hot water for the evaporation of CO2; today they use the excess heat from the refrigeration system. In this way, they save both heat and electricity.
The total savings meant that the total emission of CO2 from the production plant in Fredericia was reduced by 2,500 tonnes in the same period.
