Case Study: PRESTO W56 Process system

Cooling a Büchiglas 50 l reactor from +20 °C to -20 °C with a PRESTO W56 Process system

Objective

This case study tests the cooling capacity of the JULABO PRESTO W56 Process system with a 50 l glass reactor. The PRESTO W56 is connected to the reactor via two 2 m long metal hoses. The PRESTO W56 Process system has been programmed to cool down from +20 °C to -20 °C.
