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.
Taco’s now-expanded ECM, wet rotor Viridian line includes the VR3452 high-efficiency wet rotor variable speed circulator for chilled and hot water applications, offering up to 34 ft of shut-off head and 52 gpm flow.
The new AQ VOC from E Instruments is a compact, handheld VOC monitor and data-logger ideal for laboratories, clean rooms, hospitals, and many other applications.
The new HPC40 Series handheld pressure calibrator from Crystal Engineering, a unit of AMETEK Test & Calibration Instruments, incorporates a number of features aimed at extending the range and functionality of the compact instrument.
Palmer's new Model PTG100 Precision Test Gauge has been designed for field and laboratory applications. It can be used for precision pressure measurement and field gauge calibration, etc.
The new 2014 AQ Pro by E Instruments is an all-in-one tool for indoor air quality monitoring and real-time data logging. The product is ideal for IAQ analysis in hospitals, schools, labs, clean rooms, airports, and more. Multiple parameters can be monitored by customizing up to three gas sensors at one time.
Schebler says its Sequence Draft Control™ (SDC) design service offers boiler and hot water heater manufacturers a complete engineered venting system. SDC is capable of maintaining the desired condensing dew point of combustion, preventing excess draft which impacts efficiency and fuel/air ratio’s – especially with high turndown modulating burners.
According to Ashcroft officials, it only takes a small formation of ice deep inside the inlet cavity of a pressure transducer to destroy the sensing element. To prevent this, Ashcroft engineers have developed a unique media isolation method for the G2, T2, and KM15 pressure transducers.
The TSI PresSura™ Room Pressure Monitors and Controllers were developed to monitor safety in isolation rooms, operating rooms, and rooms for pandemic preparedness.
