New temperature control systems
Julabo has introduced two additional highly dynamic temperature control systems to its range of process circulators, the Presto A45 and A45t. The Presto A45 and A45t expand
the company’s portfolio of the newly developed Presto family. Thanks to highly effi cient technology
and powerful components, the process circulators are suited for particularly demanding temperature controls tasks
in laboratories and industrial plants; for example for the temperature control of reactors, material stress tests or temperature simulations. The units cover a working
temperature range from -45C to +250°C and provide up to 3.4kW cooling capacity. They are robust and reliable even at ambient temperatures of up to +40C. The heating capacity of the A45 is 6kW and double for the A45t at 12kW. This permits these two highly dynamic temperature control systems to compensate exothermic and endothermic reactions extremely fast. The units are equipped with powerful, maintenance-free pumps delivering up to 3.2 bar pressure and a fl ow rate of up
to 80 l/min. This guarantees high fl ow rates and constant pressure. The pump
dynamically compensates for changes of the bath fl uid’s viscosity. The pump
performance, says the company, can be controlled either in four stages or via a preset pressure value. The A45 and
A45t are operated easily and interactively via an integrated 5,7-in industrial colour touch screen. For the user this means: a clear display of values and diagrams, all information at a glance, explicit warning and help text which is easy to understand.
As with all units of the Presto family, the new products are constructed to
save space; the sides have no unwanted vents or connections. This results in the footprint being reduced to a minimum. This permits placing them close to other units or integrating them in a process plant.
