Case Study: Energy Efficiency Module

Maximize the energy efficiency of technical facilities

Challenge

The dimensioning of pumps is usually based on an operating point, which is chosen according to the expected load of the entire plant. However, this method does not take into consideration that the load is changing throughout the lifecycle of the pump and that, due to control processes, it is generally never constant in real operation (Fig. 1).

Datenmeer Solution

Analyzing the occurring operating points with Cepel Technology results in a distribution of operating points during normal operation of the facility (Fig. 2). This distribution allows to determine a very precise and realistic load spectrum. By linking the load spectrum to efficiency characteristics curves, the selection process for the specific units can be highly optimized. Additionally, this method produces an accurate calculation of the expected energy consumption, which is much more realistic than any method based on a single, estimated operating point.

Your Benefit

An accurate knowledge of the actual load spectrum as well as the resulting energy consumption supports your decision over e.g. the replacement of a pump or the use of speed regulation.

Thus Cepel allows you to fully reach the saving potentials lying in both operational energy costs and investment costs for new acquisitions.
