The Sensaphone® Airflow Sensor measures the rate of airflow and alerts data center managers when conditions fall outside the ideal range. The sensor monitors the presence or absence of cool moving air and provides relative airflow as a percentage from 0 to 100.
Alfa Laval has introduced a patented cooling concept, Low Speed Ventilation, which the company says delivers air at a considerably lower speed: 1.5 to 1.8 meters per second. Reducing air speed and delivering an optimum airflow eliminates the Venturi effect, minimizes pressure differences, and therefore prevents problems such as “hot spots.” As LSV is a normal pressure technology, data center operators only need to control air availability, not air pressure, making it easier to achieve optimum conditions in the server room.
Greenheck’s new Model EVH-501D stationary vertical blade louver is Florida Building Code Approved for use in the High Velocity Hurricane Zone and Miami-Dade Approved for use where the room behind the louver is not designed to drain water penetrating into the room or the room will house non-water resistant or water proof equipment, components, or supplies.
Greenheck has expanded its Air Measuring Damper (AMD) line with the addition of the AMD-TD series of thermal dispersion-based airflow measuring dampers. The AMD-TD series combines the functionality of a highly-accurate thermal dispersion airflow station and a low-leakage control damper to control airflow volumes to a target set point.
Continental Fan Manufacturing says its new IRIS Damper is a simple solution for fast and exact measurement, balance, and control of airflow. It is ideal for supply and exhaust tracking control, individual comfort control, and any space requiring accurate airflow regulation. Applications for the IRIS damper include office buildings, pharmaceuticals, clean room environments, and laboratories.
Tate Airflow is introducing an upgrade to the existing line of SmartAire® automatic VAV dampers. The company says the new SmartAire® MZ offers four independent control zones, a simplified user interface on the unit and on screen, and greater integration with existing DCIM and BAS systems.
Sterling HVAC announced the commercialization of the Xcelon system, a rooftop make-up air unit that combines hydronic condensing boiler technology with advanced air distribution and heat recovery methods for levels of efficiency up to 98%. Conceptualized and developed by Sterling, the Xcelon’s engineering integrates hydronic technology, a new air distribution system, and an integrated control platform to produce ultra-high efficiencies.
Tate® Airflow is introducing IsoFlo™, a fully contained cabinet. The IsoFlo cabinet offers a more efficient and flexible data center design when compared to aisle containment systems, according to the company.
Rosenberg USA released a new version of its ETRI 148V Series AC axial fan featuring an aluminum body that reduces weight by nearly 20% to less than 2 lbs. The company claims its new fans outperform competitive models in airflow by 9% and life expectancy by 33% to 50%.
