The module AFOTEK Energy enables the expansion of the real time simulation and the plant planning by the simulation of energy consumptions. This enables an individual energy analysis for the different system and production variants under consideration of the customer specifications concerning local energy and gas prices. A calculated control of the processes can reduce energy consumptions. Furthermore, to simulate and optimize the operational costs of the painting system, alternatives to reduce energy consumptions are examined (for example using the emerging waste heat) already in course of this consideration. Finally, an increased environmental awareness leads not only to cost savings for the coating company but also to an image improvement.
