    Advantages

    Disadvantages

    Liquid-to-Air,
    Non-refrigerated


    • Highly efficient
    • Economical
    • Simplest design

    • Dissipates heat into room
    • Primary recirculated coolant is always above ambient air temp

    Liquid-to-Liquid*
    Non-refrigerated


    • Quiet operation
    • Simplest design
    • Most Efficient
    • Cooling tap water is drawn only as needed

    • Primary recirculated coolant is always above secondary water temp
    • Availability of tap/facility water
    • Cost of tap/facility water

    Liquid-to-Air,
    Refrigerated


    • Best temp. control
    • Primary liquid is brought below ambient air temp.

    • Dissipates heat into room
    • More expensive than CU/CUW type

    Liquid-to-Air,
    Refrigerated Split
    System


    • All advantages of one piece RU series
    • Heat is expelled outdoors
    • Quiet operation

    • Set-up cost
    • Typically more expensive than one piece RU series

    Liquid-to-Liquid*,
    Refrigerated


    • Best temp. control
    • Quiet operation
    • Primary liquid is brought below secondary (tap) water temp
    • Cooling tap water is drawn only as needed

    • Availability of tap/facility water
    • Cost of tap/facility water
    • More expensive than CU/CUW series

    Air Circulating/
    Cooling Unit


    • Circulates /cools air as primary medium
    • Can be refrigerated or direct heat exchange
    • Suitable for rack or cabinet cooling

    • Custom built series only-consult factory for details
