Greenheck is a manufacturer of commercial and industrial air movement, control, and conditioning products, including centrifugal fans, axial fans, energy recovery ventilators, makeup air units, kitchen exhaust systems, dampers, louvers, and packaged rooftop ventilation equipment. Headquartered in Schofield, Wisconsin, Greenheck has been building ventilation equipment for over 75 years and serves commercial, institutional, industrial, healthcare, restaurant, and education facility markets. The company's CAPS and eCAPS product selection software provides engineers and contractors with performance analysis and Revit-compatible output. Commercial mechanical contractors and HVAC design engineers specify Greenheck equipment for commercial ventilation systems where a single-source ventilation catalog covers the full scope from fan to damper to energy recovery.
Product Lines
Roof-Mounted Fans
Greenheck's roof-mounted fan product line covers centrifugal upblast, downblast, inline, and utility fan configurations for commercial and industrial rooftop exhaust. Specified for general building exhaust, laboratory fume exhaust, kitchen exhaust, and industrial process ventilation where the fan must mount at the roof deck, the roof fan line spans light commercial through large industrial installations.
Energy Recovery Ventilators
Greenheck's energy recovery ventilator (ERV) line provides fresh outdoor air in compliance with ASHRAE Standard 62 while recovering energy from the exhaust air stream. ERV units transfer heat and moisture between incoming and outgoing airstreams, reducing the conditioning load on the HVAC system. Specified for schools, healthcare facilities, and offices where code-required fresh air ventilation would otherwise significantly increase energy use.
Kitchen Ventilation Systems
Greenheck has manufactured commercial kitchen ventilation components and systems since 1975, covering Type I and Type II exhaust hoods and make-up air supply hoods for restaurants and institutional kitchens. Specified for commercial kitchen projects where listed hood performance and compliant makeup air balance are required.
Dampers
Greenheck's damper line covers UL-listed fire and smoke dampers for life safety applications, control dampers for airflow regulation, isolation dampers, balancing dampers, and relief dampers for commercial and industrial HVAC systems. Specified for commercial HVAC systems where rated fire separation or precise airflow control is required.
Louvers
Greenheck's louver line includes conventional, wind-driven rain-resistant, hurricane-rated, and operable louvers for commercial building facade and equipment screen applications, controlling rain infiltration while maintaining required free area for ventilation.
Why Contractors Specify Greenheck
Greenheck has been producing commercial ventilation equipment for over 75 years from its Schofield, Wisconsin headquarters. The product line covers the full scope of commercial air movement — fans, energy recovery, kitchen ventilation, dampers, and louvers — within a single manufacturer catalog. CAPS and eCAPS product selection software provides performance data, submittal documentation, and Revit output. Greenheck dampers carry UL listings for fire and smoke applications, and the kitchen ventilation line has been in production since 1975.
FAQs
- Where are Greenheck products manufactured?
- Greenheck products are manufactured at the company's facility in Schofield, Wisconsin, where the company has been headquartered for over 75 years.
- What warranty does Greenheck offer on its commercial ventilation products?
- Greenheck warranty terms vary by product category and are available through Greenheck's official product literature and the authorized Greenheck representative for a given project.
- What's the difference between Greenheck fire dampers and smoke dampers?
- Greenheck fire dampers are UL listed devices installed in fire-rated assemblies to prevent the passage of fire through a duct penetration. Smoke dampers are UL listed devices that close in response to a smoke detection signal to limit smoke spread through ductwork. The specific required listing depends on the building's fire code and the damper's location in the HVAC system.
- What CFM range do Greenheck roof-mounted fans cover?
- Greenheck's roof-mounted fan line spans a broad capacity range covering light commercial through large industrial exhaust applications. Specific CFM and static pressure performance data by model is available through Greenheck's CAPS and eCAPS selection tools and official product documentation.
- Are Greenheck energy recovery ventilators compatible with existing HVAC systems?
- Greenheck energy recovery ventilators are designed for integration into commercial HVAC systems providing required outdoor air ventilation. Compatibility depends on the ductwork configuration, design CFM, and controls interface — Greenheck's eCAPS tool and the project's mechanical engineer confirm the appropriate ERV configuration.
- What Greenheck product is right for a commercial restaurant kitchen exhaust application?
- For commercial restaurant kitchen exhaust, Greenheck's kitchen ventilation line covers Type I hoods for grease-laden cooking equipment and Type II hoods for heat and moisture removal. The specific hood type and matched makeup air unit depend on the cooking equipment's heat output, cooking processes, and local health department requirements.
