Direct Gas-Fired Make-Up Air
Greenheck's direct gas fired make-up air units feature 92% efficient burners and are offered in a wide range of air volume and heating capacities, cooling options and configurations.
Model DGModel DG is designed to be the most economical approach to 100% outdoor air applications. Airflow volumes range from 800 to 15,000 cfm with heating capacities up to 1,600,000 BTU/hr.
Cooling option: Evaporative cooling up to 12,000 cfm.
Model DGK is designed to be the most economical, compact, and simple approach to 100% outdoor air kitchen applications. Airflow voumes range from 800 to 8,500 cfm with heating capacities up to 850,000 BTU/hr.
Model DGXs modular design provides the most configuration flexibility and expanded heating and airflor capacities. In addition to 100% outdoor air operation, recirculation and variable volume airflow options are available. Airflow volumes range from 800 to 48,000 cfm with heating capacities up to 4,800,000 BTU/hr. Cooling option: Evaporative cooling up to 46,000 cfm. Chilled water or DX cooling up to 11,000 cfm
Indirect Gas-Fired Make-Up Air
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 and 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 IGThis 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, recirculation and variable volume airflow 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
Model IGX is a highly configurable indirect gas-fired heating system that incorporates a modular design for maximum flexibility. In addition to constant volume 100% outdoor air operation, recirculation and variable air volume options are also available. The IGX also has expanded heating, cooling, and airflow capacities to provide make-up air across a broad range of applications.
- 800 to 15,000 cfm and 3 in. wg
- Up to 1,200,000 BTU/hr.
- Cooling options: packaged direct expansion, split direct expansion, chilled water, or evaporative cooling
- 16:1 electronic modulation per furnace
- ETL listed
Non-Gas Tempered Make-Up Air
Greenheck also offers non-gas tempered make-up air units for kitchen applications.
Model MSXModel MSX is ideally suited for make-up air applications where hot water, steam or electric heat are desired. The MSX 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 45,000 cfm. Heating options include steam, hot water, and electric up to 21,000 cfm. Cooling options: Evaporative cooling up to 45,000 cfm. Chilled water or DX up to 11,000 cfm
