PRESTO A45

temperature control system / process system

Reactor temperature control, tests for all kinds of substances or temperature
simulation – the new PRESTO are made for highly precise temperature
control and rapid temperature changes.
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.
