Kitchen Systems Make-Up Air Units

Greenheck offers both tempered and non-tempered make-up air systems designed to work with your kitchen exhaust system. You may select a stand-alone unit, or a combination package, which includes a combo curb, supply fan and exhaust fan. The package offers the benefit of only one roof penetration for both the supply and exhaust ducts, and provides compliance with NFPA-96.

Non-Tempered Make-Up Air

When your application doesn’t call for heating or cooling, choose from one of the following non-tempered make-up air units.

Models KSFD and KSFB

Greenheck’s untempered Make-Up Air product line includes the belt driven KSFB and the direct drive KSFD. Both have a compact design with downblast discharge providing untempered make-up air for commercial and institutional kitchen applications. Choose from a downturned or extended weatherhood. Both are designed to provide compliance to NFPA-96 when used with a combination package. Eight available blower sizes provide airflow capacities up to 10,500 cfm.

Model KSF

Model KSF supplies untempered make-up air where needed. Choose from a downturned or extended weatherhood. Both are designed to provide compliance to NFPA-96 when used with a combination package. Horizontal and downblast discharge arrangements are available. Airflow ranges from 800 to 12,000 cfm.

Direct Gas-Fired Make-Up Air

Greenheck’s direct gas fired make-up air units feature 100% efficient burners and are offered in a wide range of air volume and heating capacities, cooling options and configurations.

Model DG

Model 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

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 4,500 cfm with heating capacities up to 400,000 BTU/hr.

 

Model DGX

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 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, 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

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

Non-Gas Tempered Make-Up Air

Greenheck also offers non-gas tempered make-up air units for kitchen applications.

Model MSX

Model 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

Greenheck's Water Wizard

Greenheck's Water Wizard provides complete evaporative cooling control. The Wizard measures the outside temperature and humidity then adjusts the water supply to provide only the water needed for maximum evaporative cooling. On cool or humid days, the Wizard knows the evaporative cooling potential is low and reduces the water supply to save you money. On hot or dry days, the wizard increases the water supply to meet the increased evaporative cooling potential, providing you with the most cooling possible.
