Dynamic Reducibility DR 5000, DR 2000

DR 5000 system is designed to operate dynamic test according to ISO 13930 (Dynamic test for low-temperature reduction-disintegration – LTD)

DR 2000 system is designed to perform both Determination of the low-temperature reduction (according to ISO 11257) and Reduction Degradation (according to IS 10823 )

The equipment is based on an electric horizontal oven including two half cylindrical heating elements where the rotating reaction tube is placed.

The Control Cabinet provides for temperature, gases flow rates and tube rotation motor control.

From experiences of several laboratories involved in these tests, it has been pointed out that results reliability greatly depends on temperature and reaction gas flow rate accuracy, therefore electronic mass flow meter and high quality temperature controller are supplied.
