Specifically designed to reduce job site errors, drive productivity, and improve installation quality during pipe end preparation, the RG3212 roll grooving tool is the future of on-site field fabrication.
When designing a kitchen ventilation system, there are a number of factors that should be considered, such as project budget, building layout, surrounding buildings, system maintenance, operational cost, fire risk from grease buildup, and more.
ABB is launching a new series of variable frequency drives (VFDs) that aim to enhance the performance of smart buildings and enable users to meet more stringent energy efficiency regulations. Company officials said the new ACH580 HVAC drives ensure that applications operate reliably and without costly unplanned outages, safeguarding the comfort and security of occupants in commercial buildings, including critical facilities such as hospitals and data centers.
Greenheck’s Utility Set Fan (USF) series has expanded with the addition of the model USFD-100 direct drive utility set. Model USFD-100 can be specified with either a Vari-Green® EC motor with a speed control dial for single-phase motor applications or a NEMA premium efficiency motor with a factory-mounted variable frequency drive (VFD).
According to Greenheck, its new Model AER direct drive sidewall propeller fan moves 30% more air compared to similar fans. This allows for a smaller fan size to be specified in order to achieve desired performance while reducing first cost.
Regal Beloit Corp. will debut its Opt2MAX motor platform at the AHR Expo in Chicago later this month. Motivated by feedback from customers looking to upgrade the performance of their air handling systems, Regal engineers designed a solution to conserve power consumption in both full and part load air flow conditions.
Danfoss has received the Air-Conditioning, Heating, and Refrigeration Institute’s (AHRI) certification for variable frequency drives, confirming the performance of its VLT® HVAC Drives based on rating standards.
PennBarry has expanded its Direct Drive Dynamo centrifugal fan line by including models up to a 24-in wheel diameter and Gplus (Green Plus) EC motor options up to 2 hp. These additions will be available to order in June 2017.
Engineered Systems magazine’s March 2020 issue showcases how students at one Apple Valley, Minnesota, high school helped the facility achieve LEED Gold; how engineers can design a system to heat a building using a chilled water system, the codes and steps behind adequately design a K-12 safety shelter, and much more.
