PRESTO W93 Process system

Full cooling capacity in the low temperature range

W93 process systems offer users high cooling capacity for dynamic applications even in the lowest temperature ranges. They work with natural refrigerants and are also very energy efficient thanks to state-of-the-art technologies.

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.
