Reactor temperature control, tests for all kinds of substances or temperature simulation – Presto A30 are made for highly precise temperature control and rapid temperature changes, providing 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 fluid 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 PRESTO is the integrated 5.7’’ industrial color touch screen.
