Greenheck Make-Up Air Indirect Gas-Fired Heating

Indirect Gas-Fired Heating Greenheck's indirect fired gas heating make-up air units feature 80% efficient furnaces. Single, double and triple furnaces units are available with up to 8:1 staged turndown or 4:1 modulating turndown per furnace. All Greenheck furnaces are power vented to maximize the unit's life by preventing corrosive combustion gasses from condensing within the heat exchanger. Model IGK Model IGK is designed to be the most economical, compact, and simple approach to kitchen applications with indirect gas-fired heating. Airflow volumes range from 800 to 5000 CFM with heating capacities up to 400,000 BTU/hr. Model IGX Model IGX is ideally suited for gas-fired make-up air applications where a direct gas-fired system is not appropriate. The IGX has a modular design for broad configuration flexibility. In addition to 100% outdoor air operation, recirculation and variable volume airflow options are available. Airflow volumes range from 800 to 15,000 cfm with heating capacities up to 1,200,000 BTU/hr (input). Cooling options: Evaporative cooling up to 14,000 cfm. Chilled water or DX up to 11,000 cfm Model IG This Greenheck model features a unique indirect furnace that includes an integrated downturned plenum. This eliminates the need for an additional section to achieve a down blast discharge. In addition to 100% outdoor air operation, and recirculation options are available. Airflow volumes range from 800 to 7,000 cfm with heating capacities up to 400,000 BTU/hr (input). Cooling options: Evaporative cooling up to 7,000 cfm
