LABORATORY CONTROLS

TSI's SUREFLOW™ Fume Hood Face Velocity Controller provides a closed-loop VAV control system for proper lab hood containment. SUREFLOW assures safety by responding quickly during sash movement, or to disturbances within the sash plane, to maintain a constant face velocity and contain hazardous chemicals. SUREFLOW provides opportunities for energy savings, lower fan brake horsepower, smaller chillers and lower duct work cost by reducing the volume of air exhausted from a hood when the sash is not fully open.

Because SUREFLOW fume hood controls continuously measure average face velocity, they meet industry requirements for air flow monitors.

• Continuously measures and controls fume hood face velocity
• Provides visual, audible and alarm contacts to warn of unsafe conditions
• Meets ANSI Z9.5-2003, NFPA 45-2000 and SEFA 1.2-2002 requirements for fume hood air flow monitors
• Designed to operate either venturi valves or dampers
• Integral keypad for configuration and calibration
• Passwords limit unauthorized access
• Network communications using MODBUS, Johnson Controls N2 or optional LONworks to integrate into building automation system
