ONICON Incorporated introduced its new F-4400 Portable Clamp-on Ultrasonic Flow Meter. The F-4400 features a fluid temperature range of -40° to 300°F and operates over a wide flow range. It has a “no-moving-parts” design and does not penetrate the pipe.
SEMCO® LLC has introduced the NEUTON™, a plug-and-play controlled chilled beam pump module (CCBPM) for reducing chilled beam system installation and operational costs. According to the company, NEUTON is the industry's first proactive condensation control device for active chilled beams. It is a factory-built and pre-tested CCBPM package complete with its own powered integrated DDC, chilled and hot water connections, valves, variable-speed electronically commutated (EC) motor pumps, smart sensors and other features.
Belimo Americas has released its new inline Flow Meters (.5 in to 2 in) which aim to provide accurate and repeatable hot or chilled water flow measurement. Utilizing an ultrasonic transit time technology, the transducers perform as both emitter and receiver to provide accurate signal. The meter is multi-point wet calibrated to ensure accuracy and repeatability.
GF Piping Systems has introduced the Type 514-519 High Flow Diaphragm Valve Series. The valves are designed to provide a true break-through for weir style valves. The valve features an optimized, turbulence-free flow geometry that offers significantly increased flow rate performance and lower energy consumption, according to the company. These features expand the valve’s suitability for applications where diaphragm valves were previously not considered due to flow restriction.
ABB introduces a new range of vortex and swirl flowmeters. The new product series replaces the previous TRIO-WIRL devices. The company claims that both devices build on the advantages of ABB’s unique swirl flow measurement technology to deliver high accuracy, high reliability, and ease of installation. Plus, the new devices offer numerous innovations to save operational costs and improve performance.
Emerson Climate Technologies Flow Controls launched its new EX3 electronic expansion valve. The company says the EX3 is a stepper-motor driven electronic expansion valve that provides precise mass flow control and high energy efficiency for supermarket showcases and cold rooms with multiple parallel evaporators.
Uponor North America is launching a new stainless-steel manifold targeted for residential and commercial radiant heating and cooling applications. Made of corrosion-resistant stainless steel, the manifold is available in 1-in and 1.25-in sizes in two through eight, 10, and 12 loop configurations.
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.
Armstrong Fluid Technology has introduced a new chiller plant automation system targeted at optimizing the performance of air-cooled chiller plants. The company says the IPC 9511 streamlines plant operations and can lower operating costs. Facility managers and engineers can benefit from this fully field-configurable solution with automation features for constant speed and variable speed configurations.
Leaning on experience and data from various K-12 cities and projects, the author pursues some less conventional design approaches. They may revolve around radiant heating and/or cooling, but depending on school size and other factors, the smart use of heat recovery, DOAS, and improved central plants could also put a project on the HVAC honor roll.
