    Carriers air-cooled split systems: provide a logical solution forcommercial needs

    have a rugged, dependableconstruction

    Features/BenefitsThese dependable splitsystems match Carriersindoor-air handlers and direct-expansion coils with outdoorcondensing units for a wideselection of commercialcooling solutions.

    Up to 11.0 EERThe high efficiency split commercial splitsystem combining the 38ARZ/ARDoutdoor condensing unit with 40RM air

    handling unit can save 20-27% of energyconsumption.

    Constructed for long lifeThe 38ARZ (single circuit, scrollcompressor) and 38ARD (dual circuit,

    scroll compressor) models are designed and

    built to last. The copper tube-aluminum finoutdoor coil construction provides years oftrouble-free operation. Where conditions

    require, a range of Enviro-Shield coilprotection options are available. Cabinets

    are constructed of prepainted galvanizedsteel, delivering unparalleled protectionfrom the environment. Inside and outsidesurfaces are protected to ensure long life,good looks, and reliable operation. Safetycontrols are used for enhanced system

    protection and reliability.

    ProductData

    The 38ARZ/ARD condensing units with scrol l compressors match Carriers 40RMindoor-air handlers for a wide selection of dependable commercial cooling solutions.
