Integrated Venturi Heating Elements For Air Curtains
US Patent:
8568210, Oct 29, 2013
Filed:
May 17, 2010
Appl. No.:
12/800469
Inventors:
David A. Johnson - New Castle PA, US
Assignee:
Berner International, Inc. - New Castle PA
International Classification:
F24F 9/00
US Classification:
454188, 454193, 392360
Abstract:
An air curtain resistant heating system including multiple heating coils integrated within blower fan cages. The multiple heating coils defining an inflow venture air pattern for increased heat transfer and fan cage internal flow vortex dependent on coil flow conveyance. Coil orientation placement assures limited impact to effect blower pressure and therefore minimizes loss of air performance parameters. Multiple phase electrical supply for multiple paired heating coils positioned in corresponding multiple blower fan units in an air curtain assembly.
