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.
