Ultrasonic output power is a key factor for process scale-up. In order to process larger volumes in a given amount of time, you need to deploy more power. The power per device ranges from 500 watts to 16 kilowatts. For typical liquid processing applications, four or more units are combined in clusters for enhanced redundancy and capacity adaptability. For example, a cluster of 6xUIP10000 (60kW) may be used for the processing of up to 50 cubic meters of biodiesel per hour!
High power equipment uses more electricity. Considering rising energy prices, this affects the costs of processing. For this reason, it is important, that the equipment does not lose much energy in the conversion of electricity into mechanical output. Hielscher ultrasonic processors have and outstanding efficiency of >85%. This reduces your electricity costs and gives you more processing performance.
