Case Study: PRESTO W91 Process system
Cooling a QVF 50 l reactor from +20 °C to lowest possible temperature with a PRESTO W91 Process system
Objective
This case study tests the lowest temperature of the JULABO PRESTO W91 Process system with a 50 l glass reactor. The PRESTO W91 is connected to the reactor via two 2 in. metal hoses. The PRESTO W91 Process system cools from +20 °C to -88 °C maximum low temperature.
