The electric utility industry is undergoing a major transformation driven by new sources of energy generation (solar and wind power), consumer demand for faster and more affordable services, cybersecurity, and big data.
LG Electronics unveiled an enhancement to its flagship VRF system. The Multi V 5 is now standard with LGRED° (Reliable to Extreme Degrees) heat technology. The company says the Multi V 5 with LGRED° is an ideal year-round VRF solution. Available in a range of capacities including a compact 20-ton single frame, the Multi V 5 offers advanced features.
Larson Electronics released an 80-watt explosion proof 12-inch exhaust fan recommended for use in hazardous locations and with toxic gas sensors (not included). This 850-cfm unit is weather resistant and wall mounted featuring internal motorized and external fixed louvers.
Larson Electronics LLC has released a new hazardous location convection heater for active heating in dangerous environments and cold-temperature work sites. This 3,600-watt heater operates on 240V three phase power and is ideal for manufacturing plants, chemical processing, refineries, industrial control rooms, airflow systems, heat circulation, ambient temperature management, grain silos, and more.
Greenheck has added Model RBD-15 to its line of remote balancing dampers. Constructed of heavy gauge galvanized steel, Model RBD-15 is a multi-blade balancing damper rated for pressure differential up to 4 inch wg. and velocities up to 2,000 fpm.
Greenheck’s newly designed Premium Model SP bathroom exhaust fans now offer low sound ratings as low or less than 0.3 sones. Available in six sizes, SP-A50 through SP-A190, the fan features insulated housings and vibration isolators between the motor and housing to contribute to quiet operation.
Parsons announced the acquisition of Williams Electric Company, a privately-owned, value-added company specializing in control system integration, electrical and general contracting, and energy infrastructure solutions.
Mitsubishi Electric recently introduced its CITY MULTI® ceiling cassette indoor unit, featuring the new 3D i-see Sensor™. The 3D i-see Sensor is a small component mounted to the exterior panel of the ceiling cassette. The sensor continuously analyzes the thermal profile of a room, identifying cool and warm spots. To achieve an accurate thermal profile, it performs hundreds of circular scans, with multiple points per scan, continuously monitoring.
On Demand Harmonics in electrical systems are normal occurrences due to non-linear loads such as AC to DC supplies and Variable Frequency Drives (VFDs). We will review how the IEEE Recommended Practice and Requirements for Harmonic Control in Electric Power Systems (Standard 519) applies to harmonics disturbances at a system level. This webinar will provide an understanding of what harmonics are in electrical systems and how VFDs create them.
On Demand Our society has become highly dependent on electrical power. It is the underpinning of virtually everything, and we take it for granted in everyday life at home, work, and in many cases, public transportation. Moreover, virtually all of the critical infrastructure for communications, security, emergency services, and life safety depend on power. Climate Change, in general, and the record weather extremes will continue to increase the likelihood of utility power interruptions as well as risks to life and property. In the new age of 100-year events becoming more commonplace, it has become clear that there is virtually no place that is totally immune to natural risks. Therefore, backup power has become almost as important as primary utility service, and, in many cases, it's a necessity.
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.
