 In the last several years, the industry has been abuzz from the concept of fan arrays. In an effort to bring greater clarity to design and control of fan arrays, Energy Labs published a whitepaper by an independant consultant, Holcombe Kelly. This paper looks at fan sizing, effficiency, acoustics, redundancy and control strategies.
Energy Labs believes there is an optimum number of fans for each application and set of job requirements. Only by analyzing total energy use (uincluding actual motor efficiencies), sound requirements, maintenance costs, space considerations and system redundancy issues, can the designer select the optimum number of fans to be selected.

 Prefab is Lean Success
Joe Cullen
President, C.P. Blouin
Pre-fabrication provides a better product in the end, says contractor Charles P. Blouin’s president Joe Cullen. “Everything is put together in a supervised environment, which means it’s not out on a job with wind and dust blowing.”
It’s a process that has eliminated wasted materials and time. “We take a sheet of metal at one end of our shop and walk out with a finished product,” says Blouin superintendent Bob Stokes.
“In the past, we brought little pieces out to the job site. They would get moved around, scattered, and sorted multiple times. We don’t have that now. We pick up the metal, take it to the shop, assemble it, send it to the job site, and deliver it to the room where it belongs,” Stokes adds. Often pre-fab pieces are installed the day they are delivered.
Before he could implement this process, Cullen had to convince general contractors that just-in-time delivery would work. “We stressed the benefits—no space required for storage or assembly; instead of having guys walking around looking for things, they were actually doing their jobs.”
His argument works, and Blouin is better equipped than ever to compete in the marketplace. “Now we take [the duct work] up to the floor and walk this 15-foot-long piece right into a room. The hangers are up for it, and we literally walk into a room, put it on a lift, and raise it right into place,” says Cullen.

Buckley has upgraded the exterior insulation thickness to a 2” R-6 insulation on our locally manufactured flexible duct. This includes the following models:
Needless to say, the Vektor fans had to arrive on site and on schedule! It's not everyday the Boston Fire Department allows the Harvard University to shut down access to the campus and secure surrounding streets to allow a helicopter rig.
