Case Study: PRESTO A45 Process system
Cooling a Chemglas 20 l reactor from +20 °C to -10 °C with a PRESTO A45 Process system
Objective
This case study tests the cooling capacity of the JULABO PRESTO A45 Process system with a 20 l glass reactor. The PRESTO A45 is connected to the reactor via two 2 in. long metal hoses. The PRESTO A45 Process system has been programmed to cool down from +20 °C to -10 °C.
