Case Study: PRESTO W55 Process system

Cooling a Büchiglas 100 l reactor from +150 °C to +20 °C with a PRESTO W55 Process system

Objective

This case study tests the cooling capacity of the JULABO PRESTO W55 Process system with a 100 l glass reactor. The PRESTO W55 is connected to the reactor via two 2 m long metal hoses. The PRESTO W55 Process system has been programmed to cool down from +150 °C to +20 °C.
