JULABO's air-cooled PRESTO A38 process system uses environmentally friendly, natural refrigerant. It combines high performance and a very compact design with all the advantages of the PRESTO series for a working temperature range from -45 °C to +250 °C.
The highly dynamic temperature control systems PRESTO are designed for high-precision temperature control for a wide range of applications such as reactor vessels or material stress tests. Moreover, by using efficient components, the process systems can compensate exothermic and endothermic reactions exceptionally fast. Permanent internal monitoring and self-lubricating pumps ensure a long life-time. In addition, numerous interfaces offer many remote control possibilities across networks or for integration into higher-level control systems.
