Howden American Fan Company has announced the availability of a wide range of fan product lines ideal for serving industrial boilers, gas turbine installations, and heat-recovery steam generators in combined cycle installations. Howden says it works closely with OEMs to supply a high-quality industrial product that meets specific air flow and pressure requirements. Also available are start-up and commissioning and after-market service and repairs.
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 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.
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.
