Case Study: PRESTO A30 Process system

Cooling a QVF 6 l reactor from +20 °C to lowest possible temperature with a PRESTO A30 Process system

Objective

This case study tests the lowest temperature of the JULABO PRESTO A30 Process system with a 6 l glass reactor. The PRESTO A30 is connected to the reactor via two 2 m metal hoses. The PRESTO A30 Process system cools from +20 °C to -12 °C maximum low temperature.
