PRESTO A80 Process system

2-stage process system for low temperatures

As air- or water-cooled versions, the units with 2-stage refrigeration unit offer high cooling and heating capacities for lowest temperatures down to -80 °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.
