It is common when choosing a temperature control system to make decisions by comparing manufacturer catalogue data; but, this can be misleading as heating and cooling power specifications give very little indication of performance. Good temperature control is about efficient heat transfer to the application which results in smaller less expensive units, reduced resource consumption and increased process profit margins.
The
primary role of a thermoregulator is to control and change the temperature of
an application and this is dependent on the thermoregulators ability to
transfer heat energy to the process. The efficiency of thermal energy transfer
depends on the volume of heat transfer fluid, the surface area exposed to the
heat transfer fluid and the flow rate of the fluid over the surface of the heat
exchanger.

Unistats are a range of hydraulically sealed temperature control systems with a
temperature range of -120 °C to +425 °C. Unlike conventional thermostats they
have no internal bath, reducing the heat transfer fluid volume to a low
minimum. The plate heat exchanger provides a large surface area over which the
thermal fluid flows and low pressure pumps ensure that high flow rates are
achieved, dramatically improving the speed and efficiency of heat transfer.
These refinements give Unistats the ability to generate a wide Delta T between
the process and jacket temperature, allowing heat to be quickly and efficiently
added or removed from the process. Once the desired set point temperature is in
range the Unistat reduces the Delta T and calculates the amount of energy
required to ensure that the target temperature is reached without overshoot.
To
demonstrate the benefit of effective heat transfer Huber produced a range of
case studies showing the real-time performance of Unistats in combination with
a range of reactors. Over 200 case studies are available to download from the
Huber website and can be filtered by unit or application, allowing a
comprehensive search; providing valuable performance data when choosing the
right system for your process.
When
the priority is reproducible results and tight temperature control,
thermodynamically there is no alternative. It’s simple, high flow rates +
efficient thermal energy transfer = good temperature control!
To
demonstrate the performance of the Unistat range over 200 case studies have
been carried out. They show the Unistats unique ability to adapt to process
requirements, offering precise stability and control.
