College of Nanoscale Science and Engineering


The College of Nanoscale Science and Engineering (CNSE) of the University at Albany–State University of New York (SUNY) is a global education, research, development and technology deployment resource in nanotechnology. Ventrol supplied a sectional rooftop air handler for a cleanroom installation on campus in 2012.

The unit was originally designed as a knock-down rooftop unit because access to the roof was limited due to the crane pick. Helicopter lifts were ruled out due to a nearby operating chip fab building that couldn’t shut down. The contractor found a crane with a large enough reach to lift the smaller sections of the Ventrol air handler onto the roof curb.

  • Cleanroom rooftop unit with third layer roof system with center vestibule
  • U-shape tunnel design with 6,150 cfm @ 7.12” TSP delivered by a three-FANWALL® array with individual VFDs for full system redundancy
  • Stainless steel interior including floor grating, EMT conduit, floors and liners
  • 4” hybrid foam thermal break technology, drainable welded floors
  • Multiple levels of filtration, including gas phase; integrated adiabatic humidification


  • FANWALL TECHNOLOGY® maximizes uptime with airflow redundancy. “Near Zero” pressure drop backdraft dampers allow for fan isolation without air recirculation
  • Sectional construction enables unit sections to be lifted into hard-to-reach places
  • Stainless steel construction holds up against wash-down environment for long life


  • Ease of installation
  • Redundancy
  • Space savings
  • Corrosion resistance • Energy efficiency
  • Low maintenance
