Mütek™ DFR-05 Drainage Freeness Retention meets modern mills’ demanding requirements
Designed to streamline the measurement of key process parameters, BTG’s next-generation DFR-05 and state-of-the-art ChargeView software are helping mills and chemical suppliers boost efficiency and cut chemical and energy costs.
A few months ago BTG announced the next-generation version of its Mütek DFR-05 Drainage Freeness Retention, a highly advanced laboratory instrument that automatically measures these three key process variables.

With more than 30 new units and upgraded versions now out in the field, we’re delighted to be able to share some of our customers’ feedback:
"We did a comparison between a ‘standard’ SR device, our previous DFR model and DFR-05. Standard SR and DFR-05 show the same value, and we got a good comparison of + - 1°SR."
"We had used the previous model for some years. Now, having the new version, it’s really great to be able to perform retention aid trials in no time."
"The new Mütek ChargeView software is clearly structured and easy to handle. I like the platform concept for running all Mütek LAB units using one software application. The feature allowing the unit to run in standalone, and to be able to import all data and calibration sets, show that this new concept has been carefully thought through."
