Case Study: PRESTO W91tt Process system

Cooling a Büchiglas 100 l reactor from +20 °C to -50 °C with a PRESTO W91tt Process system

Objective

This case study tests the cooling capacity of the JULABO PRESTO W91tt Process system with a 100 l glass reactor. The PRESTO W91tt is connected to the reactor via two 2 m long metal hoses. The PRESTO W91tt Process system has been programmed to cool down from +20 °C to -50 °C.
