Case Study: PRESTO W50t Process system
Cooling a QVF 30 l reactor from +20 °C to -20 °C with a PRESTO W50t Process system
Objective
This case study tests the cooling capacity of the JULABO PRESTO W50t Process system with a 30 l glass reactor. The PRESTO W50t is connected to the reactor via two 2 m long metal hoses. The PRESTO W50t Process system has been programmed to cool down from +20 °C to -20 °C.
