Aspen introduced the LGM Series high-efficiency, multi-position, aluminum coil 120-volt air handlers, which offers outstanding installation versatility. The 2- to 4-ton units are shipped as upflow or horizontal-right and can be converted for downflow or horizontal-left installations on-site by HVAC technicians. When a proper metering device is used, the LGM Series units are ETL listed for use with R-22 or R-410A refrigerants. In addition, they can be Air-Conditioning, Heating, and Refrigeration Institute (AHRI)-certified with most brands of air conditioners or heat pumps.
When properly installed and tested in accordance with ASHRAE standard 193, the sturdy, fully insulated galvanized steel cabinet offers less than 2% air leakage. A factory-provided knockout for duct return is standard on all LGM Series models, which feature an easy-access door for coil cleaning.
