Case Study: PRESTO A80t Process system
Cooling a Asahi 20 l reactor from +20 °C to -40 °C with a PRESTO A80t Process system
Objective
This case study tests the cooling capacity of the JULABO PRESTO A80t Process system with a 20 l glass reactor. The PRESTO A80t is connected to the reactor via two 1 m long metal hoses. The PRESTO A80t Process system has been programmed to cool down from +20 °C to -40 °C.
