Refrigerated & Heating Circulator Demo
Video showing SJ refrigerated and heating circulators for temperature control, sample preparation, and process support applications.
What this video shows
SJ refrigerated and heating circulators support external temperature-control tasks in sample preparation and process equipment. They circulate a thermal fluid rather than freeze-dry a product. Select a circulator by the required operating temperature and heat-transfer duty, not by freeze-dryer batch capacity.
Questions for your project
Which information is needed to choose a heating and cooling circulator?
Provide the operating temperature range, fluid, process heat load, required flow and pressure, hose length and connected equipment. Electrical input power is not the same as cooling capacity at the requested operating temperature.
