Huber’s Unistat “Petite Fleur” is a little flower with an impressive ability to control the process temperature of reactors much larger than itself. Here we see it connected to a 20-litre un-insulated 20-liter glass reactor from Chemglass. The process mass is simulated with 15 litres of “M40.165/220.10“, a heat transfer fluid from the Huber range. The graphic below shows the ability of the Petite Fleur to heat the process to 120°C then cool it to 70°C and then on to 20°C. The stability at each set-point is plain to see and demonstrates that the “little flower” is still well within it’s comfort zone.
