Temperature Control System / Process System
PRESTO provide large heating and cooling capacities covering a working temperature range from -92 °C to +250 °C. Highly efficient components allow extremely fast compensation of exothermic and endothermic reactions.
Lab users benefit from high flow rates, constant pressure, and a controlled build-up of pump pressure. Changes in the temperature-control liquid’s viscosity are balanced dynamically. Permanent internal monitoring and self-lubricating pumps contribute to the new PRESTO®’s long service life.
A special feature of the new PRESTO is the integrated 5.7’’ industrial touch screen.
All important information is displayed clearly and concisely enhancing ease of use considerably.
The new PRESTO can be operated intuitively with the tip of your finger.
As the new PRESTO operate whisper quiet, you will hardly hear them in your laboratory. Even high room temperatures of up to +40 °C will not make the new PRESTO sweat. Maintenance-free pumps and drives guarantee operational readiness.
Multiple interfaces permit remote control of the PRESTO® across networks and in superordinated control systems. The Design does away with venting slots at the sides. The required installation space is reduced to an absolute minimum.

Tip: Counter-cooling your PRESTO with a Recirculating CoolerIf there is no cooling water, the PRESTO W80t can be cooled down with a recirculating cooler with a cooling capacity of 3 kW at a flow temperature of 15°C. The required circulating pump has to ensure a flow rate of 2 l/min at a counter-pressure of 0.5 bar. The recommended minimum tank volume is 15 liters.
