Case Study: PRESTO W91tt Process system
Cooling a Ace Glas 100 l reactor from +20 °C to lowest possible temperature with a PRESTO W91tt Process system
Objective
This case study tests the lowest temperature of the JULABO PRESTO W91tt Process system with a 100 l glass reactor. The PRESTO W91tt is connected to the reactor via two 3 m metal hoses. The PRESTO W91tt Process system cools from +20 °C to -84 °C maximum low temperature.
