Advertorial Greenheck TECHNOLOGYPROFILE Powerful Vektor-MD™ Broadens Greenheck’s Lab Exhaust Line reenheck is quickly establishing itself as a leader in the lab exhaust system market with its patent pending Vektor-MD™ High Plume Dilution System. Less than two years ago, Greenheck introduced the Model Vektor-H, a cost-effective solution for high school, university and hospital labs. The new Vektor-MD is substantially more powerful and ideal for professional labs where higher concentrations of hazardous, contaminated air can be exhausted and adequate plume height achieved. “We know the requirements for discharging contaminated air from institutional, industrial and biosafety labs are far more demanding, and that’s why we designed the Vektor-MD,” said Tony Rossi, Greenheck’s Director, Laboratory Exhaust Systems. Unique Vektor design In developing the Vektor-MD, Greenheck engineers used state-of-the-art computational fluid dynamics and testing analysis to design a patent pending, unique discharge nozzle design. The Vektor’s nozzle entrains additional ambient air that not only effectively dilutes exhaust effluent but also increases mass flow and velocity which creates greater discharge momentum and propels the diluted effluent high above the roof. In fact, the low-profile, compact Vektor-MD unit can discharge up to 80,000 cfm of noxious exhaust air at 8 inches of static pressure per fan and provides plume rises in excess of 150 feet. Vektor-MD is available in various single, double, triple and quadruple stack configurations. Cost-effective alternative for schools Greenheck’s Vektor-H, while not as powerful as the Vektor-MD, is a perfect alternative for school and hospital labs where concentration of noxious fumes is typically lower. The unique design of the Vektor-H nozzle helps increase the velocity of the exhaust air and displaces it high above the roof where it cannot contaminate the roof, re-enter the building’s make-up air system or drift down on surrounding neighborhoods. Vektor-H is available in single, double or triple stack configurations with flow applications from 500 cfm to 24,000 cfm per fan. Two great choices Both Vektor-H and Vektor-MD lab exhaust systems meet ASHRAE and ANSI Z9.5 guidelines, and both systems are UL/cUL 705 listed. G Laboratory exhaust is drawn into the Vektor-MD fan (a), mixed with ambient air (b), and discharged at high velocity (c). Both the Vektor-H and Vektor-MD are AMCA certified, with the Vektor-H licensed to bear the AMCA label for sound and air performance, and the Vektor-MD licensed to bear the AMCA label for air performance. In addition, both lab exhaust systems are available with spark resistant construction and an optional bypass air plenum and damper that add more ambient air to the exhaust stream. Greenheck also designed both systems with fan components and motors outside of the contaminated air stream ensuring safe, easy access during maintenance.
