if it is not efficiently transferred to the
Circulation pumps are ideally
designed so that a turbulent flow generates large heat transfer coefficients
(alpha value) and thus efficient heat
transfer to/from the internal heat exchangers (evaporator and heating). In
practice, 90 percent of all applications
use glass, such as reactors, distillation
apparatus, etc., and the permissible
system pressure in these applications
is maximum 0.5 bar.
Installation of devices and
The installation and setup of the total system is often considered as something that is almost incidental. There are numerous
aspects that have a direct influence on the tempering capacity. An
example of this is that the quality and consistency of the tempera-ture-control hoses have a direct effect on the achievable outputs.
For example, metal hoses with smooth inner walls improve the
flow characteristics and heat transfer, which results in consider-
able time savings when heating or cooling. Additional points with
negative effects are restrictions at hose
connections, unnecessarily long hoses
or small cross-sections of the hoses or
Case studies for output
Case studies are often helpful as
sources of information for procurement
decisions. In case studies, heating and
cooling processes are documented and
typical scenarios, such as the control
response during an exotherm, are
demonstrated. Case studies facilitate
reliable predictions as to whether a temperature control device is
suitable for the planned purpose.
When selecting a circulator there are several points that need
to be considered. Ultimately, it is not only the heating and cooling
capacities stated in the manufacturer’s catalog that are relevant.
Rather, criteria such as the cooling density, flow rate and, if avail-
able, case studies should be paramount since that is the only way
to make a realistic assessment of the heat transfer efficiency.
