These manometers feature extended service intervals The a-Baratron Capacitance Manometer (photo) has a high tolerance to ambient temperature changes. Internally heated to 45, 80 or 100°C, this manometer offers full-scale measurement ranges from 0.1 to 1,000 Torr, and service intervals that are up to four times longer than previous models, says the company. Its all-digital architecture and new sensor-heating system contribute to longterm reliability. Corrosion-resistant, due to its nickel-alloy construction, these manometers can be flexibly configured for many existing or new processing systems. — MKS Instruments, Andover, Mass. www.mksinst.com These compressors have new energy-saving features The SFC 30 (photo) and SFC 30S compressors are variable-drive rotary screw compressors with updated specific-power features, 30
including a direct-drive design, premium efficiency motors, lower internal pressure differentials and optimized screw elements. Builtin heat-recovery options provide further energy savings. Other new features on these compressors include enhanced cooling systems, integral moisture separators (with drain), and electronic thermal management. The SFC 30S has a flow range of 37–171 ft3/min at 125 psig and is available with pressures up to 190 psig. The SFC 30 has a flow range of 47–202 ft3/min at 125 psig, with pressures up to 217 psig. — Kaeser Kompressoren SE, Coburg, Germany www.kaeser.com Use this flowmeter to optimize air-gas ratio in burners The ST75 Air/Gas Flowmeter (photo) measures fuel gas, process gas, inert gas, waste gases and air in a variety of small line sizes. Designed to optimize air-gas ratio for control of burners in boilers,

ovens and heaters, this flowmeter provides three outputs; the mass flowrate, the totalized flow and the media temperature, allowing users to monitor and control fuel and air requirements. The ST74 is designed for small line sizes (0.25–2 in. diameter), making it useful in a wide variety of industries, including chemical processing, electric power, food and beverage, pharmaceuticals and semiconductors. Offering direct-flow measurement with thermal dispersion technology, the ST75 eliminates the need for additional pressure and temperature sensors or flow computers. There are also no orifices or inlets to clog or foul, significantly reducing scheduled maintenance and unplanned shutdowns. — Fluid Components International LLC, San Marcos, Calif. www.fluidcomponents.com These stackers are designed with ergonomics in mind The PowerStak line of compact fully powered stackers (photo) have been
