Engineers are always discovering new applications for these blowers, including radon mitigation, cooling, fume evacuation, air cushion machines, and more.
Despite their complex appearance, fan curves are fairly easy to interpret once one gains an understanding of the conventions and terminology used, enabling selection and specification of the best fan for an application.
Because unit heaters and other non-centralized heating products offer low upfront cost and easy installation, HVAC contractors and building owners commonly use these systems in warehouses; distribution centers; multi-line retail applications; garages; and other large, high-bay facilities.
When Major League Soccer club the Real Salt Lake Monarchs embarked on building the largest pre-engineered, free-span facility in North America, a critical concern was efficiently heating the space during the cold Utah winter months.
For over 60 years, Fuller's has been Chicagoland's finest carwash. Their mantra — “We protect your investment so it can give you the long life you expect.
Nidec Motor Corporation (NMC) has launched the U.S. MOTORS® brand 3-10 hp electronically commutated (EC) motor with an IE4 (Super Premium efficiency) rating integrated with a tuned VFD. The product is available for variable torque pumps, fans, blowers, farm vents, and hydronic pumps. This motor is a member of the ACCU-SERIES line of variable speed products.
Browning has introduced its latest notched V-belts with the benefits of EPDM heat-resistance and durability. The company has added an expanded temperature rating of -60°F to 250°F to some of the most commonly used V-belt cross sections in the HVAC industry: AX, BX, CX, 3VX, 5VX, and 8VX Gripnotch belts.
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.
