Cooper&Hunter added a new series to its current heat pump line-up with single-zone applications. The new Dakota series aims to ensure consistent warm comfort during extreme climate and the condenser heat output capacity allows the unit to work efficiently as a primary heat source even if the temperature drops to a sub-zero level of minus 22ºF.
Danfoss says it has engineered a solution that safely controls hot gas injection with the ICSH Dual Position Solenoid Valve. Complying with the latest IIAR safety recommendations for soft gas applications, the ICSH Dual Position Solenoid Valve provides a gradual, time-controlled opening for a smooth pressure build-up in the evaporator before it opens the flow to 100% for full defrost.
Carrier announced the commercial availability of its AquaEdge® 19DV in North America. The centrifugal chiller features Greenspeed® intelligence and a low global warming potential (GWP) refrigerant R1233zd(E), which has a GWP of ~1. Carrier officials said the AquaEdge 19DV has an efficiency that is more than 40% higher than ASHRAE® 2016 guidelines, has low sound, and is capable of series counterflow configurations.
Danfoss has released its new EVR v2 solenoid valves, having completed a wide series of improvements to the range of EVR valves throughout 2017. The company says the reinforcements and rationalization now make the valves capable of accommodating higher refrigerant pressure and a broader range of applications while reducing the references, inventory, and servicing time.
Weil-McLain® has enhanced its high-efficiency SlimFit™ 1,000, 1,500, and 2,000 MBH commercial condensing boiler line with the advanced capabilities of the Unity™ Controller. The company says the upgrade is designed to reduce installation and set-up time for contractors, simplify boiler system design for specifying engineers, and improve control interface commonality and communication across the entire Weil-McLain high efficiency boiler line.
Extech Instruments has launched new environmental meters optimized for HVACR and IAQ professionals. The series includes an airflow meter, a combination hygro-thermometer and psychrometer, and a 10-in-1 multifunction meter. The company says the new compact instruments are designed to provide quick and accurate readings on a range of environmental conditions that are essential for HVACR troubleshooting and repairs, as well as IAQ assessments to improve occupant health and comfort.
ITW Vortec has updated its line of enclosure coolers. The ProtEX Vortex A/C enclosure cooler has been granted certification for Class I, Division 1, Groups A, B, C and D; Class II, Division 1, Groups F and G; and Class III, after review by UL.
SEMCO LLC has introduced the NEUTON™–Multiple Zone, a controlled chilled beam pump module (CCBPM) capable of controlling active chilled beams in up to five small rooms in office buildings, hospitals, schools, or other commercial buildings.
EVAPCO has developed the eco-LSWE closed circuit coolers with an ellipti-fin coil and CrossCool™ internally enhanced tubes to increase the heat transfer of the coil, in turn improving the unit’s cooling capacity. The units range in capacity from 340 to 16,987 MBH.
On Demand Back-up power has become almost as important as primary utility service, and in many cases a necessity. This has caused a wide variety of organizations to consider adding or upgrading back-up power to their existing facilities, or including them as a requirement for new buildings. When a utility disruption occurs everyone expects the back-up generator to start and run flawlessly as long as necessary, whether for thirty minutes or 30 days. However, while simple in principle, different applications place different demands and requirements for back-up power systems.
On Demand In this segment of our webinar series, we will examine the issues of fuel autonomy, storage capacity, and other related topics to consider when specifying, selecting, and installing an emergency backup power system.
Engineered Systems magazine’s April 2019 issue focuses on K-12 schools, showcasing how districts across the nation are using hybrid systems and advanced BAS systems to cut their energy use and costs, how kitchen ventilation systems should be installed and maintained, and more. The issue also examines the present and future of artificial intelligence in the built environment, one engineering firm’s advanced attempt to create a nonproprietary BMS system, and much more.
