Berner International Corp., New Castle, Pa., the leading U.S. manufacturer and innovator of air curtains, expanded its In-Ceiling Mount (ICM) Series by adding the FCB, the HVAC industry's first in-ceiling flush mount air curtain rated for doorways with up to 16-foot-high ceilings in hotels, hospitals, office buildings, schools, and other commercial facilities. 

Efficient one-hp motors combined with Berner's proprietary Pro-V Nozzle design, which generates 50 percent more velocity at the floor versus standard ceiling mount units making the FCB's unprecedented 16-foot range possible. The improved velocity also allows for lower speed operation resulting in up to half the decibel ratings and energy consumption of competing in-ceiling air curtains. The Pro-V Nozzle also produces a doorway-sealing laminar airstream that's superior in velocity, volume, and uniformity. 

The FCB, which is available in 3 to 12-foot lengths, features a high-style, low-profile faceplate available in white polyester-coated aluminum or stainless steel. It's also available in custom color, powder-coat aluminum faceplates that offer an aesthetic choice for engineers, interior designers, and architects.  

For supplemental heating, the ICM Series offers electric, steam, and hot water options. The electric heating option draws air through the industry's first electric heater using the Venturi effect. The strategic design and positioning of a heater on each blower's intake outperforms competitors' obstructing placements in the discharge airstream, which can degrade discharge velocities by as much as 40 percent. Berner's proprietary heater placement design also minimizes turbulence and disruption of the Pro-V nozzles' long-reaching laminar airstream. The heaters' easy serviceability requires removing only two mounting screws and a quick-disconnect cable.

The ICM Series comes standard with Berner's proprietary Intelliswitch, the most advanced and easiest-to-install digital control package in the industry.

Because the ICM Series is certified by the Air Movement & Control Association-International (AMCA), it complies as a vestibule substitute, which is now allowed by the International Green Construction Code (IgCC), an approved overlay of green construction products to the base code International Energy Construction Code (IECC). Laboratory research studies conducted by Berner's R&D department with results certified by computational fluid dynamics (CFD) analysis from second-party research/validation consultant confirm air curtains are 10-percent more energy-efficient than vestibules. Substituting vestibules with air curtains can also save tens of thousands of dollars in construction costs per doorway.

Other FCB features are:

  • Meets fire and life safety codes by drawing clean air directly from the lobby–without the need of costly field-installed ductwork–rather than contaminated air within ceiling spaces;
  • Applicable to both retrofit and new construction;
  • Cuts maintenance costs with a cleanable, reusable media filter;
  • External service panel requires no ceiling panel removal and allows easy accessibility for component replacement or microprocessor control programming; 
  • Minimizes insect and vehicle emission infiltration;
  • The Intelliswitch is designed with self-diagnostic capabilities. Personal technical support is available during business hours, or at a 24/7 online FAQ and troubleshooting page.

The FCB is a perfect complement to the FCA, which is an AMCA-certified in-ceiling mount air curtain introduced last year for 8 to 12-foot-high ceilings.
