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.
Schaffner EMC introduces the ECOsine® Active 3420, a harmonic filter which provides harmonic compensation in real-time for industrial and commercial environments. With a capacity of 30 to 300A, operating at 200-480VAC (+/- 10%), the connection-ready 3420 (3-wire) cabinet models include forced air cooling and internal liquid cooling (200-300A), for the power electronics.
Greenheck’s new Model APD plenum fan features a direct drive fan with the wheel connected to the motor shaft. With no fan shaft bearings or belts to maintain, the company says its Model APD eliminates the cost and maintenance associated with traditional belt drive plenum fans.
Engineered Systems magazine’s September 2019 issue questions the need for multiple building codes that cover the same subjects, examines the dos and don’ts of power systems for critical facilities, offers tips on how to select the proper centrifugal pump circuit flow controls, and much more.
