Description
Temperature Control System / Process System
Reactor temperature control, tests for all kinds of substances or temperature simulation – the PRESTO are made for highly precise temperature control and rapid temperature changes. 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. Permanent internal monitoring and self-lubricating pumps contribute to the PRESTO's long service life. The integrated 5.7" industrial touch screen displays all important information clearly and concisely enhancing ease of use considerably.

Tip: Counter-cooling your PRESTO with a Recirculating Cooler
If there is no cooling water, the PRESTO W85/W85t can be cooled down with a recirculating cooler with a cooling capacity of 7 kW at a flow temperature of 15°C. The required circulating pump has to ensure a flow rate of 6 l/min at a counter-pressure of 0.5 bar. The recommended minimum tank volume is 30 liters.
