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 />
