ClimateMaster AGL20ACG 20kW 3.5-6 Ton Duct Heater

The ClimateMaster AGL20ACG Duct Heater is an electric pipe heating assembly used to provide supplemental heat in air distribution systems. It operates at a 20kW heating capacity and is designed for 3.5 to 6 ton HVAC system compatibility, delivering resistance-based heat output through elements placed in the airflow path. HVAC systems use this duct heater inside air handlers and rooftop units to raise supply air temperature during heating demand conditions or low ambient operation. The unit connects into duct sections where passing air absorbs generated heat before distribution to occupied spaces in commercial and residential installations, supporting controlled thermal balance in conditioned operations.
