The Climate 6000 AH air handler series provides commercial and industrial customers with improved IAQ by introducing outside air and removing undesired exhaust air or large-space comfort conditioning. Intended for large industrial and commercial applications such as manufacturing and medical facilities, supermarkets, conference centers, schools/universities, etc., the series comes in 21 different sizes. Horizontal unit configurations range from 800 to 38,000 CFM, while vertical configurations are available in 800 to 4,000 CFM. They are built to allow service access and incorporate modular design for configurability. Sandwiched double-wall R-13 construction reduces weight and allows either indoor or outdoor installation. Corner-post gasketing and double tongue-and-groove assembly provide efficient thermal performance, virtually eliminating thermal bridging. Direct-drive, composite plenum fans and factory variable-speed drives provide efficiency, low sound and redundancy. Low lead times offer semi-custom solutions, ideal for replacement jobs. The standard blower assembly consists of direct-driven inverter-duty totally enclosed, fan-cooled motors, with an airfoil fan wheel.
