PRESTO W92tt Process system
Highest cooling capacity of 27 kW and heating capacity up to 36 kW
The W92 class process systems are extremely powerful and can also simulate extreme environmental conditions. They are used, for example, in the temperature control of vacuum chambers for component testing in the aerospace industry.
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.
