The coolant supply uses in typical applications of metal cutting manufacturing on average 50 % of the electrical energy. A main optimization option is the retrofit of demand-based control strategies in the supply system. Previous studies showed that a high saving potential remains in pressure filter plants for coolant cleaning. The plants are operated constantly on an excessive power level, independent on the coolant demand. A concept of a demand-based control is introduced and evaluated in simulations using the example of precoat filters. The analysis at an existing plant shows an energy saving potential of up to 73 %.
