Dynamic Reducibility DR 5000, DR 2000

Control Cabinet includes complete top quality control and monitoring instrumentation. Temperature of sample is driven by digital programmer and controller to obtain best isothermal test condition.

A temperature alarm controller assures oven safety cutting off power in case of over temperature. Automatic inlet of Nitrogen and Reaction gas is provided according to temperature program. The power to the gear motor is also automatically supplied.

Gas flow control is obtained by a digital mass flow controller for reaction gas and by a rotameter for N2 (as option a mass flow meter also for N2 is included). Manual gas and motor control is also possible for checking purpose. A Touch screen recorder and data logger, and Ethernet connection, provide local and remote recording of test data.

The electric oven consists of a steel structure placed on a basement and including the heating elements and insulation material.
The rotation at the proper revolution speed is provided by means of a gear motor placed inside the basement. A dust separator is placed at the end of gas line in order to collect dust and powdered matter coming from rotating tube.

Reaction tube is manufactured according to ISO Standard dimensions and materials: all parts operating at high temperature are made of heat resistence Stainless Steel to obtain long tube life.

Internal lifters, as required by the standard, are placed inside the tube. A gear wheel on the reaction tube gives the rotation in connection with the geared motor in the basement.

Reaction Tubes

Two heat diffusers are placed at the end of the tube in order to reduce temperature of outlet gas flow.
