Recirculating Chillers

Recirculating chillers don't have an internal bath, but rather continuously pump water or other fluids through their system in order to cool it for external cooling applications.

If you want a device that has both an accessible internal bath and can pump fluid from the bath externally, then you want a circulator with external pumping capability.
