Magnum 91 Temperature Control System


JULABOMagnum 91 Temperature Control System

Magnum 91 - Highly Dynamic Temperature Control System

The ,Magnum 91 highly dynamic temperature control system is the ideal solution for demanding external temperature applications, like e.g. temperature control of reactors up to 50 litres. The advantages are rapid heat-up and cool-down within the working temperature range from 91 to +250C as well as an immediate control of exothermic and endothermic reactions. The water-cooled unit offers a heating capacity of 6 kW as well as a cooling capacity of up to 5 kW. With the intelligent ICC cascade temperature control rapid results with high precision are reached. For time and temperature depending processes there is an integrated programmer with 6x60 program steps. Additionally the system has a closed tempering circuit, here the advantages are a reduced oxidation and a longer lifetime of the bath fluid unpleasant odors and vapors do not get outside.
