GDX-50/80 Heating/Cooling Circulator, −80°C to +200°C, 17L, for 50L Jacketed Reactors

GDX-50/80 Heating/Cooling Circulator, −80°C to +200°C, 17L, for 50L Jacketed Reactors

This all-in-one unit chills and heats a single closed fluid loop. It covers −80°C to +200°C, so it can run cold winterization and crystallization and then switch to heating for decarb or solvent work, all on the same jacketed reactor with no second machine and no swapping fluids. It uses a cascade refrigeration system and a 6 kW heater. Cooling capacity is about 15.3 kW near room temperature and still 650 W at −80°C. The circulation loop is sealed with an expansion vessel, which keeps the fluid from absorbing moisture at low temperatures or oxidizing at high temperatures. The pump moves 35 L/min with 12 m of lift.
