PRESTO process systems

working temperature range -93 °C to +250 °C

An entirely new generation of highly dynamic temperature control systems by JULABO. The new PRESTO systems are designed for precise temperature control as well as rapid temperature changes, making them ideal for reactor vessels, material stress tests, or temperature simulations. These instruments cover a working temperature of -93 to +250 °C with high cooling and heating capacity.

Highly efficient components give these instruments the ability to compensate for exothermic and endothermic reactions with extraordinary speed. Permanent internal monitoring and self-lubricating pumps contribute to the new PRESTO’s long service life. The integrated 5.7-inch color industrial-grade touch panel is one of the identifying characteristics of the new PRESTO. It gives the user a clear and well-organized view of important information while greatly improving user-friendliness. Once in operation, the new PRESTO® units are whisper quiet and barely audible in a laboratory. The new PRESTO® units are extremely robust and work reliably even if the ambient temperature climbs as high as +40 °C. Multiple interfaces permit remote control of the PRESTO® across networks and in superordinated control systems. Closed side panels without ventilation slits reduces to a minimum the amount of space needed to operate.
