Case Study: PRESTO W80 Process system

Cooling a Rettberg 5 l reactor from +100 °C to +20 °C with a PRESTO W80 Process system

Objective

This case study tests the cooling capacity of the JULABO PRESTO W80 Process system with a 5 l glass reactor. The PRESTO W80 is connected to the reactor via two 1 m long metal hoses. The PRESTO W80 Process system has been programmed to cool down from +100 °C to +20 °C.
