Carrier Z Series rooftop units are pre-wired and factory- tested in both cooling and heating modes. All 48Z models feature an industrial grade cabinet with fully hinged access panels. Standard forward-curved supply fans provide superior supply fan performance of up to 4 in. external static pressure (ESP) while optional airfoil supply fans provide fan performance up to 6 in.ESP.
Units are available in dedicated vertical supply/return airflow models for constant volume (CV) or variable air volume (VAV) applications. A wide variety of gas heating options are also available. Units come with the ComfortLink™ DDC (direct digital control) communicating control system and semi-hermetic compressors on dual independent thermostatic expansion valve (TXV) controlled refrigeration circuits.
