11 kW cooling capacity for dynamic temperature changes down to -91 °C
Best heating capacity combined with high cooling capacity – those are the key features of the W91 units. The units are just as ready for embedding into pilot plants as they are for use in material and component testing.
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.
