Case Study: PRESTO W50 Process system
Cooling a Büchiglas 100 l reactor from +100 °C to +20 °C with a PRESTO W50 Process system
Objective
This case study tests the cooling capacity of the JULABO PRESTO W50 Process system with a 100 l glass reactor. The PRESTO W50 is connected to the reactor via two 2 m long metal hoses. The PRESTO W50 Process system has been programmed to cool down from +100 °C to +20 °C.
