Frequently asked questions
What is the difference between a recirculating chiller and a cooling thermostat?
A recirculating chiller is primarily intended for continuous process cooling without an integrated heating function. A cooling thermostat combines cooling with precise temperature regulation and is suitable for both internal bath applications and external temperature control.
When should you choose a recirculating chiller?
A recirculating chiller is suitable when you only need to remove heat from an external system, for example for instrument cooling or process cooling under constant thermal load.
