With unmatched excellence in direct-fired heating, ventilating, and make-up air systems, AbsolutAire has expertise in indirect-fired systems as well. Indirect fired heat technologies meet specific customer preferences and are common choices for many commercial, institutional, and industrial applications in which the higher capacities, displacement ventilation solutions, and fuel efficiency of direct-fired systems are not required.

AbsolutAire I-Series indirect-fired heating and ventilating systems are available in horizontal and upright configurations for either indoor or outdoor installation. Like most indirect fired heaters, these units are 80% energy efficient and use only the best heat exchangers in the furnace section to provide building supply air at set temperatures. Depending on the application, these systems may be gravity or power vented for exhausting combustion gases to the outdoors.

Many of the same design features found on AbsolutAire direct-fired units can be found on our indirect-fired units. These include motorized dampers, advanced filtration, evaporative and mechanical cooling, specific control systems, long life motor and fan combinations, single point gas and electrical connections, and ETL/CSA certifications.
