E Flow Technologies presents SMARTPACK™ flexible fan packs. A range of customizable axial fan packs, SMARTPACK is engineered to meet stringent low-noise and efficiency requirements in industrial and commercial ventilation, refrigeration. and heat exchange applications.
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.
Continental Fan’s UBV Upblast Roof Ventilators provide aerodynamically efficient performance with airflow capacities to 61,000 cfm. The ventilator is constructed with a heavy duty welded steel base, galvanized butterfly exhaust damper section, and a spark resistant cast aluminum airfoil axial impeller.
Ruskin model DFD-LP Low Profile, Low Pressure Drop Dynamic Fire Damper is designed for dual directional air flow. The damper is constructed with an integral sleeve/frame and an aerodynamic shaped blade for high-velocity applications.
Ziehl-Abegg has added a new motor size to its line of motors, allowing the company to offer a new fan that is quieter, more efficient, with improved aerodynamics. This completion of its product range of energy-saving EC motors accompanies the introduction of new impellers.
Berner International Corp. has introduced a patented Venturi-style heater design, which the company says will offer a more aerodynamic, electric heated air curtain with improved air performance efficiency by up 40% The VTH electric heater combines a hemispherical heating element array with an innovative mounting strategy at the blower inlet. The patented design uses the Venturi effect to draw air through the heating element via the blower inlet before it enters the discharge airstream. The discharge airstream velocity remains unobstructed in a near 100% efficient heat transfer, full laminar pattern for an optimum aerodynamic performance. Company officials said that this creates a near perfect environment-separating air seal across any open doorway while providing auxiliary heat, as needed.
Engineered Systems magazine’s June 2019 issue examines the role of HVAC systems and power in colleges and universities via the decentralization of a Missouri college’s central boiler plant, an examination of ventilation considerations in Group R-2 facilities, the steps engineers should consider when overcoming unanticipated boiler room setbacks, common calculations and considerations regarding NFPA 92, and much more.
