PRESTO A70 Process system new

2-stage process system for low temperatures

The air-cooled PRESTO A70 is JULABO's most compact 2-stage process system and offers high cooling capacities for lowest temperatures down to -75 °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.
