Greenheck is the leading supplier of air movement and control equipment that includes fans, dampers, louvers, kitchen ventilation hoods, and energy recovery and make-up air units. Greenheck equipment is used in all types of commercial, institutional, and industrial buildings in applications from comfort ventilation to manufacturing processes.
The sidewall propeller fans include both direct and belt-driven fans with fabricated steel, aluminum, or cast aluminum blades. These fans are suitable for clean air applications, including exhaust, supply, filtered supply and reversible. Typical applications are factories and warehouses.
- Collaborate with multiple firms to design and manufacture a unique, direct-drive “Utility Duty” sidewall fan.
- Design the fan to be easily mounted between existing building framework (90” x 90”) and provide convenient, side access to the fan and dampers.
- Deliver 103 housed fans in phases over six months to match the contractors’ precise scheduling needs.
- Custom-built Direct Drive “Utility Duty” sidewall propeller fan and housing with easy access
Multiple full-scale prototypes were built within a strict timeline to ensure that the design matched specific requirements.
- Several on-site visits from the contractor and electrician ensured everything was well understood by all parties, paving the way for an efficient installation process.
- The final design incorporated a special direct drive utility duty propeller housed in a specially designed 90” x 90” wall housing. The custom blade and pitch propeller met the air, sound, and horsepower requirements. The unique oversized access panels provide a means for servicing and maintaining internal components including Greenheck’s industrial control dampers (Model ICD-45, utilizing a two-actuator drive system
- Labor saving items such as single point wiring and lifting lugs installed prior to shipping made installation easier and more efficient.
Jay Swoboda, project superintendent from Tweet-Garot Mechanical Incorporated praised the teamwork of all parties. “Greenheck’s experienced engineers had the knowledge we needed to meet the unique ventilation requirements.” This project became a reality, he said, “because of the superior coordination, prototyping, and on-site visits.”
