The WARTA NTT-610 is a wall-mounted electric thermal air curtain with a built-in fan heater, designed to protect doorways serving areas around 60 in heated coverage. Mounted above an entrance, it drives a flat stream of warmed air across the opening, separating indoor and outdoor climates: heat stays inside in winter, dust and insects stay out, and the doorway remains fully passable for customers and goods.
Air curtains repay their cost through reduced heating losses at frequently opened doors — the standard economic argument distributors use with retail and logistics end customers. At approximately 90 USD with a 20-unit minimum order, the NTT-610 is positioned for HVAC wholesalers, electrical distributors and project suppliers equipping shops, offices, warehouses and public buildings.
The Russian manufacturer produces the line serially for harsh-winter markets, a credible origin story for thermal equipment, and ships export-packed units with mounting hardware and documentation.
