Omega introduced its new series of rangeable, very low differential pressure transmitters which can output either static (gage) pressure or differential pressure. The PX2600 series has four unidirectional and four bi-directional ranges, three selectable outputs (0 to 5 Vdc, 0 to 10 Vdc, 4 to 20 mA 2-wire), pushbutton or remote zero, and four-digit LCD with the ability to show either static or differential pressure.
B&K Precision is offering three new models of its high power programmable DC power supplies, models PVS10005, PVS60085, and PVS60085MR. The new PVS Series delivers output power up to 5.1 kW. The company says they deliver excellent regulation, low noise, and fast transient response times. All models provide a built-in solar array simulator (SAS) function to generate photovoltaic I-V curves. Offering high-power density in a compact 2U form factor, these DC power supplies are suitable for high voltage testing up to 1000 V, motor inverter testing, and solar array testing applications.
DuctSox has added the SkeleCore Pull-Tight™ to its SkeleCore™ line of internal framework systems for fabric duct air dispersion. Pull-Tight is a solution for commercial, institutional, and industrial buildings requiring the benefits and performance of textile HVAC duct, but without the sagging, wrinkling, movement, and sound associated with conventional non-tensioned fabric duct.
Greenheck has expanded its line of mixed flow inline fans with the addition of Model EQB. According to Greenheck, the fan combines the best properties of centrifugal and vane axial fans while providing higher efficiency and lower sound levels. Model EQB’s octagonal housing is manufactured of formed galvanized steel panels coupled with a heavy-gauge steel drive frame for and durability.
Larson Electronics has released a Class 1 Division 1 explosion proof fan/blower designed for use on a 220 volts AC electrical power system. This explosion proof blower meets UL and ATEX standards for hazardous locations and provides high 4,450+ cfm output for effective airflow in larger spaces.
Baldor Electric Company has unveiled the Dodge HT500 synchronous drive system. The company says the motor delivers high torque, low maintenance, and potential energy savings with less overhung load than V-belts drives. Officials also said HT500 belts also offer longer life in wet/oily environments than rubber made products.
Trane is introducing an enhanced Trane® Optimus™ helical rotary water-cooled chiller now available with the Trane® Adaptive Frequency™ drive (AFD). The AFD adjusts motor speed based on demand to reduce energy consumption and, as a result, energy costs. The Optimus chillers have cooling capacities ranging from 150 to 430 tons, making them ideal cooling solutions for most buildings, including high-occupancy schools, hospitals, and hotels.
Viconics has released the latest addition of its VT8000 Series Room Controllers: The VT8300 Low Voltage Fan Coil and Zone Controller. The company says the VT8300 provides increased energy savings and comfort at a lower price point compared to a full building automation system.
The PR-Series from Addison provides fresh air for critical facilities such as schools and universities, health care facilities and hospitals, and hotels and resort complexes. Addison recently introduced the PR-Series semi-custom packaged rooftop system for commercial, institutional, and industrial applications. The company says the series is a highly efficient, packaged rooftop heating and air conditioning system that offers design flexibility with a wide selection of factory options, as well as the ability to accept custom options for specific job requirements.
A few circumstances in a data center make it ripe for a CHP design to boost efficiency. Let’s get into the options within both relevant chiller types, why payback may be shorter than expected, and the assorted potential benefits from lower costs to higher reliability. Some tips from an array of manufacturers’ reps round out this useful investigation.
