Lab simulation of drainage, freeness and retention processes onsite
The Mütek™ DFR-05 Drainage Freeness Retention simulates the retention and drainage conditions prevailing in a paper machine immediately before and during sheet forming. Chemical addition is fully automatic via a dosing module. The optionally available RET-20 Lab Sensor directly measures the filtrate consistency, making a manual determination of stock and ash consistencies superfluous. The drainage behavior is characterized by gravimetry of the filtrate volume.
The Mütek™ DFR-05 is designed for use with a PC and application software. The RET-20 Lab sensor is optional. The instrument is intended for indoor use at temperatures in the range of 15 °C to 40 °C (59 °F – 104 °F). It is rated for voltages of 100 - 240 VAC at 50 Hz / 60 Hz.
The DFR is also available as a special freeness version, the Mütek DFR-05 Freeness.
