RBI has introduced the latest edition to its ultra-high efficiency condensing boilers and water heaters. The Infinite Energy2 (IE2) utilizes a state-of-the-art Radial Variable Circulation (RVC) stainless steel heat exchanger for maximum heat transfer and operating efficiencies of up to 98%.
A new selection of test and measurement equipment called Digi-Sense™ has been introduced by Davis Instruments. The equipment includes temperature, humidity, airflow, and light meters as well as manometers in an expanding line of products. The company says the tools are rugged enough for rigorous use and arrive precalibrated for time and cost efficiencies.
E Instruments has unveiled its new AQ Comfort tool for IAQ monitoring. The all-in-one Instrument provides the indoor air quality monitoring and real-time data logging for IAQ analysis in homes, schools, offices, and more.
Baldor Electric Co.’s Dodge® Hydraulic ISAF bearing is now available with higher load ratings. The Hydraulic ISAF pillow block bearing with a patented hydraulic mount and dismount system is now available with higher capacity, 231 series spherical bearings, and is interchangeable with industry standard SDAF housing dimensions.
Bitzer is now offering a range of compressor units for use with the natural refrigerant ammonia (R717). The Bitzer ammonia compressor packs (ACP) are available with a capacity range of 100 to 450 TR. The modular compressor units comprise up to three compressors. For higher capacities, as many as three compressor packs can be connected (up to 9 compressors) and connected to a single controller, increasing the overall capacity up to 1,200 TR. The company says this is ideal for industrial systems.
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.
Baltimore Aircoil Company has launched the new Series 1500 Cooling Tower. The company says its Series 1500 Cooling Tower is one of the most serviceable units without compromising performance and fit. The cooling tower has capacity increases of up to 13%, new configurations almost doubling the tonnage range, reduced sound solutions, 26% reduction in annual maintenance costs, and reliable year-round operation.
Continental Control Systems has introduced the CTRC Rogowski coil current transformer. The device is designed to simplify installations to meet the increasing demand for accurate current measurement on conductors where traditional split-core and solid-core CTs are difficult to use. With its flexible design, the CTRC is ideal for large bus bars and irregular-shaped conductor bundles. The new coil offers a small, flexible profile, enabling it to be used on conductors in tight spaces where rigid CTs won't fit.
Navien’s new NPE-S series condensing tankless water heaters have a rated efficiency of 0.98EF. The company claims the series is ideal for commercial and residential water heating applications and is available in three models with maximum inputs from 150,000 to 199,900 Btuh and maximum flow rates from 8.4 to 11.1 gpm.
Bradford White recently has added its Icon HD™ Commercial Control System to the company’s 100-gallon, 399,999 Btuh eF Series® ultra-high efficiency water heater. The ICON HD™ is an intelligent Honeywell® integrated control with a digital LCD display that combines temperature control, diagnostic codes, system functions, and operational status into a single, intuitive control unit.
