Case Study: PRESTO W92tt Process system
Cooling a Büchiglas 100 l reactor from +20 °C to -20 °C with a PRESTO W92tt Process system
Objective
This case study tests the cooling capacity of the JULABO PRESTO W92tt Process system with a 100 l glass reactor. The PRESTO W92tt is connected to the reactor via two 3 m long metal hoses. The PRESTO W92tt Process system has been programmed to cool down from +20 °C to -20 °C.
