Frequently asked questions about Julabo

What is the difference between a circulator and a recirculating chiller?

A circulator combines temperature control with heating and/or cooling for internal and external applications. A recirculating chiller is primarily designed for continuous process cooling without an integrated heating function.

What does 2-stage cooling mean?

2-stage cooling refers to a two-stage refrigeration system that enables higher cooling capacity and lower minimum temperatures for demanding applications.

For which applications is external temperature control suitable?

External temperature control is used for reactors, heat exchangers, and test setups where precise regulation of an external circuit is required.
