There has been a deluge of recent technological advancements that are creating new air curtain applications that were barely imaginable 10 years ago.
Advancements have ranged from more efficient electric heaters to manufacturing improvements that now extend lengths up to 16 feet. Air curtains that were once only custom-manufactured with explosion and spark-proof components for hazardous industrial locations are now standardized catalog items. What was once an energy-saving device for industrial shipping doors is now embraced by retailers, hotels, restaurants, and food service operators as tools for saving energy, eliminating flying insect infiltration, and increasing employee air comfort.
