CRI Test System is available in three versions:
Single Oven System, Double Oven System, Dual Oven System.
Single Oven System
To perform one test at time.
Double Oven System
To improve the number of tests that can be performed.
At the end of the test in the first oven it is possible to start immediately a new test on the second oven. It is not necessary to wait for oven cooling down as in single oven system.
Dual Oven System
To allow simultaneous operation of two ovens running, fully independently, two tests at a time. The system is provided with independent Carbon Dioxide and Nitrogen lines, together with independent temperature control and programming units.

Vertical electric oven
The electric oven consists of a steel structure placed on a frame and including the silica insulation material. Twenty silicon carbide high temperature heating rod elements are placed horizontally in a stack and are grouped in 5 heating zones to provide separate power control. Replacement of heating elements is fast and easy with no need of refractory maintenance so that oven life is very long.
Inner high temperature chamber is protected by a quartz tube.
The oven can be equipped, as an option, with a weighing system to provide continuous monitoring of coke sample weight during reduction test.
Control panel includes complete top quality control and monitoring instrumentation.
Temperature of coke sample is driven by digital programmer and by multiloop digital controller to obtain the best isothermal test condition. A temperature alarm controller assures oven safety cutting off power in case of over temperature.
Automatic inlet of Nitrogen and Carbon dioxide is provided according to temperature program. Gas flow control is obtained by a digital mass flow meter for CO2 and by a rotameter for N2 (as option a mass flow meter also for N2 is included).
Manual gas control is also possible for checking purpose. Optional weighing system allows continuous monitoring of sample weight.
A Touch screen recorder and data logger, and Ethernet connection, provides local and remote recording of test data.
Reaction tube is manufactured according to ASTM and ISO Standard dimensions and materials: all parts operating at high temperature are made of INCONEL 600 steel alloy to obtain long tube life.
A copper tube coil assures cooling down of exhaust gases. The reaction tube can be hung to the optional roof electric tackle to provide safe and easy insertion and removing into the furnace.
TB 5000 for CSR determination
Tumbler device for CSR test consists of a wall mounting double drum system. TB 5000 allows to run two sample tests simultaneously.
The unit is equipped with:
- Electric motor and gear box
- Variable frequency drive (TB 5000 –ISO)
- Digital pre-set counter (to set up total number of revolutions)
- Positioning feature (for a slow motion for loading/unloading purpose)
- Safety cage
- Safety switch on the door
- Emergency Stop button
In the ISO Version the high accuracy in the revolution speed is assured by the Variable frequency drive that allows a fine adjustment of the speed to 20 ± 0,1 r.p.m.
