Case Study: PRESTO A80 Process system

Cooling a Asahi 20 l reactor from -30 °C to -60 °C with a PRESTO A80 Process system

Objective

This case study tests the cooling capacity of the JULABO PRESTO A80 Process system with a 20 l glass reactor. The PRESTO A80 is connected to the reactor via two 2 m long metal hoses. The PRESTO A80 Process system has been programmed to cool down from -30 °C to -60 °C.
