Unistat ® <strong>510w</strong><br />
Controlling simulated exothermic reactions<br />
within a Chemglass 50-litre glass reactor<br />
Requirement<br />
This case study shows the effectiveness of a<br />
Unistat <strong>510w</strong> connected to a 50-litre reactor in<br />
the control of a three simulated exothermic reactions<br />
of differing strengths at 0 °C and 20 °C<br />
generated by an electric immersion heater.<br />
Method<br />
The Unistat and reactor were connected using<br />
two 1.5 m insulated metal hoses. The reactor<br />
was filled with 37 litre of “M90.055.03”, a Huber<br />
supplied silicon based HTF.<br />
Results<br />
Once the “reaction” was under steady control<br />
the heater was turned “Off”.<br />
It can be seen how rapidly the DT between the<br />
process and jacket is increased to “suck” the<br />
thermal energy from the process to restore and<br />
maintain the process temperature set-point.<br />
The results can be viewed in the following<br />
