Project Feature: 101 College St. – M.K. Plastics Lab Exhaust Fans

Laboratory exhaust systems are a vital component to lab design. Without a properly designed lab exhaust the safety of occupants and life surrounding the facility are put at risk. What happens when an entire building is comprised of lab space? Who can be trusted with the safety and well-being of a laboratory’s occupants, not to mention energy consumption? Such was the case for Winstanley Enterprises at 101 College Street.

The Challenge

Flow Tech was tasked with providing lab exhaust for 101 College Street, a multi-tenant, 10-story lab building in New Haven, CT. Laboratories are notorious for producing corrosive air streams and therefore require a large volume of airflow to keep building occupants safe, and to help dilute exhausted air, keeping the people living, working and walking around the facility safe. The bigger challenge was to fit the necessary equipment into a smaller than usual footprint.

Luckily, Flow Tech was named basis of design for this project. Being basis of design (BOD) allowed the mechanical contractor, MJ Daly, to feel confident that our design would work and the submittal process would go smoothly. In addition to BOD, having worked with MJ Daly on numerous projects over the years only aided in this project’s success.

View of 101 College St. from the drive into downtown New Haven. You can see the first (8) M.K. Plastics fans on the rooftop. Now this rooftop view is blocked by a weather barrier.

The Solution: M.K. Plastics Lab Exhaust Fans

Flow Tech provided (16) M.K. Plastics lab exhaust, high plume dilution fans. The fans are steel coated and designed for lab exhaust applications. Induced flow nozzles help increase three important factors:

  1. Outlet velocity – force in which air is exhausted
  2. Plume height – height reached by exhausted air
  3. Exhaust dissipation – breaking up the exhausted air and spreading it widely

A stacked design was agreed upon to condense the exhaust fan layout and overall footprint. The fans were installed on top of grating, and stack extensions were utilized to align all exhaust outlets to the appropriate height.

If you look closely you can see how the fans are stacked on top of grating.

Other Flow Tech Equipment/Controls Featured

VAW Systems Sound Attenuators

To combat the noise, each fan features a VAW inline sound attenuator to help dissipate the sound of the airflow moving though the fan. Without sound attenuation the noise generated by the airstream traveling through the lab exhaust could disrupt not only the building’s occupants but people walking by the building as well.

ABB Variable Frequency Drives (VFDs)

ABB ACH580 VFDs were also purchased by MJ Daly and control the motors on the M.K. Plastics fans.

Air Monitor Corp. (AMC) Airflow Stations

AMC airflow stations measure the exhausted airflow to ensure the fans are pulling the correct amount of airflow through building. The airflow stations were purchased by the controls contractor, Johnson Controls.

Phoenix Controls Critical Airflow Control

Phoenix Controls’ critical airflow control system is safely supplying and exhausting air directly to and from lab space.

Flow Tech Service

Lastly and certainly not least, Flow Tech’s field service technician, Nick Fitzner, successfully started up the system. He ensured the programming and equipment functioned properly.

Results

Winstanley can now ensure safe and efficient laboratory space for it’s current tenants, Alexion Pharmaceuticals and Biolabs. The building’s design and lab exhaust system has diversity built in for future lab tenants to move in and be operation with minimum down time.

About 101 College Street

101 College Street is a $250 million state-of-the-art life sciences building managed by Winstanley Enterprises. The 525,000 SF, 10-story lab building will be anchored by Connecticut-bred life science companies including Alexion Pharmaceuticals (subsidiary of AstraZeneca), Biolabs and Yale University. Additionally, the building includes a 48,000 square foot, world-class incubator to foster life sciences start-up companies in Connecticut.

The project represents the next phase of the City of New Haven’s Downtown Crossing initiative which involved dismantling Route 34, reclaiming 12 developable acres to support the growing life science industry, and reconnecting the Medical District, Union Station and the City’s Central Business District.
