Lab Controls

​Owners demand flexible facilities that ensure safety for their researchers. Engineers are not only tasked with designing facilities for the current science mission but also for future, unknown needs. Both engineers and owners want to provide energy efficient buildings that don’t risk safety or comfort. AirGenuity’s ControlSMART™ critical space solution ensures safety, flexibility, and the lowest possible energy footprint for your facility.

CRITICAL SPACES HAVE CONSTANTLY EVOLVING, DEMANDING REQUIREMENTS.

Fume hoods are designed to be the primary barrier between the science and researchers.

Ensuring accurate face velocity as the fume hood sashes move is the primary determinant of how safe your fume hoods truly are. AirGenuity’s ControlSMART™ sash position sensor and venturi valve’s 1.5 second speed of response ensures your safety is not compromised as sashes are moved. Maintaining accurate and constant pressurization in your room, the secondary barrier isn’t a nice to have, it is a must. Potential contaminants in critical spaces must be contained to ensure the safety of unaware occupants in adjacent spaces aren’t negatively affected. AirGenuity’s matched supply and exhaust venturi valves ensure matched speed of response and accuracy to maintain room pressurization under all operating conditions.​

Critical spaces are constantly evolving. Science changes every 3-5 years and yet critical spaces,

once constructed typically remain static for many years. The high turn down ratio of the ControlSMART™ venturi valves allow you flexibility to change ACH rates up and down as the Lab air flow requirements change. The AirGenuity ControlSMART™ venturi valves are constructed of stainless steel to ensure an optimum level of corrosion protection, ensuring flexibility in your laboratory facility regardless of what type of research is being conducted today or tomorrow.

Critical Spaces are typically one of the most expensive spaces for owners to operate. High

Air Change Rates (ACH), single pass 100% outside air and fume hood exhausts result in

high levels of ventilation. The ControlSMART™ valves, when paired with a facility Demand

Control Ventilation (DCV) strategy can drastically reduce room air change rates, while still meeting all code requirements. Occupancy sensors on hoods ensure that when sashes are left open with no one present, air flow can be reduced or the sashes can be closed. High turn down ratios of up to 20:1 of our venturi valves ensure the lowest air flow possible when sashes are closed, while providing for maximum air flow when the room is being purged. This high turn down ratio assures your lab ventilation system operates at the lowest air flows yet has the capacity to purge the room when required thereby saving energy.

Hood Controls

The hood controls system consists of sash position sensors, a face velocity monitor / alarm annunciator, and a variable volume venturi air valve. The face velocity controller is typically mounted on the venturi valve. The sash sensor is mounted on the top of the hood and attached to the sash. A factory calibrated variable venturi valve provides accurate and stable exhaust air flow control and hence face velocity. The fume hood monitor is mounted on the front side panels of the hood to confirm safe hood operation, alert the user of potential system malfunctions, and provide manual override functions. The hood control system accepts sash sensor inputs and controls the fume hood exhaust air flow to maintain the set constant face velocity to provide virtually instantaneous response. In about one second from when the sash comes to rest, the air flow is modulated to within ±5% of the target air flow to ensure constant fume hood face velocity. The fully distributed microprocessor-based controller of the hood control system is capable of operating other air flow and PID control loops in the lab. One hood control system is required for each fume hood for maximum user safety.


Room Controls 

Maintaining accurate and constant pressurization in your room, the secondary barrier isn’t a nice to have, it is a must. Potential contaminants in critical spaces must be contained to ensure the safety of unaware occupants in adjacent spaces aren’t negatively affected. AirGenuity’s matched supply and exhaust venturi valves ensure matched speed of response and accuracy to maintain room pressurization under all operating conditions.


Snorkel Control

Snorkels which run continuously can drive significant energy usage by increasing the total exhaust. Strategies which reduce flow such as on off operation or timers can ensure occupant needs and lab safety are achieved while simultaneously reducing operational carbon and costs
