    Circulating Cooler

    Overview Knowledge Standards Terms
    The circulating cooler absorbs heat through the refrigerant cycle, transferring the heat generated by equipment or reactions to the external environment to maintain stable system temperatures. It is used in applications requiring temperature control, such as laboratory instruments and chemical reactions.
    Selection
    When selecting a recirculating chiller, it is essential to consider the cooling capacity to match the equipment, ensure the temperature range covers the usage requirements, verify media compatibility, account for the influence of ambient temperature, evaluate pump flow and pressure parameters, and consider the device's dimensions and noise levels.
