Temperature Control System PRESTO® A40 / W40
Julabo


Highly dynamic temperature control systems. Designed for precise temperature control as well as rapid temperature changes, making the units ideal for reactor vessels, material stress tests or temperature simulations. The instruments cover a working temperature range of - 92 to + 250 °C with high cooling and heating capacity. Highly efficient components give the instruments the ability to compensate for exothermic and endothermic reactions with high speed. High flow rates, constant pressure and a controlled build-up of pump pressure. Changes in the temperature-control liquidás viscosity are balanced dynamically. Permanent internal monitoring and self-lubricating pumps contribute to the PRESTO®'s long service life.
