How Do Constantly Opening Glass Doors Affect Fragrance in an Appliance Store?

They make the first few metres of the floor a place where fragrance does not stay, and the honest thing to do about that is nothing. Here is the mechanism, because owners deserve to know why the entrance smells of the street no matter what they buy. A glass door on a busy frontage opens and closes dozens of times an hour. Each time, the pressure difference between inside and outside - the AC pushing out, the wind or the mall's own air pushing in - swaps a slab of air across the threshold. The zone inside the door, three to five metres deep on most floors and deeper on a windy corner, is therefore refreshed with outside air continually. Fragrance released into that zone leaves with it. The open door is the defining fact of scenting retail, and it has no fragrance solution. Not a stronger machine, not a second machine by the door, not a higher setting - each of those puts more fragrance into air that is on its way out and, because the same output also reaches the rest of the floor, over-scents the displays where the air does stay. The advisor at the desk ends up breathing a level nobody chose in order to make a doorway smell of something for thirty seconds at a time. So the rule is inward. Place the source well past the threshold zone, high on a wall the AC supply crosses, out of the door's line of draught, so the fragrance is released into air that circulates on the sales floor rather than air that is queuing to leave. The wall mount on the SOSA Vaayu is what makes that possible; the socket by the door is the worst place on the floor and the one most machines are found in. Then judge the level from where the air stays - the specification table, the far display kitchens - with the team at five in the afternoon, and lock it. The key-lock matters more on a busy-door floor than anywhere, because the door is a daily temptation to turn it up and levels on a shop floor only ever drift one way. Should the machine go near the entrance or deeper inside is this argument as a placement decision, and what customers should smell when they enter explains why the entrance being a draught is fine: the fragrance is noticed at the first display and forgotten by the specification table, and the door is not on that list. There is one thing you can do about the door, and it is not a fragrance thing. Close it when you can, keep the second leaf shut on a double door, and if there is a lobby or an airlock use it; a mall unit with a permanently open frontage is a harder case still, and the threshold zone is simply wider. Machine and price: one Vaayu at ₹11,999, waterless, wall-mounted inward, timer and key-lock, for a connected floor of roughly 1,500-3,000 sq ft; a Mountain Breeze or Morning Freshness reed at the desk, away from the door, for a studio. And the frame: fragrance is an interiors decision, like lighting or music. SOSA makes no claim that it changes dwell time, footfall, conversion or sales, no claim about what it does to any appliance or finish, and it is never a substitute for ventilation, cleaning or extraction. The live kitchen and coffee counter stay unscented. Ask for a showroom scenting plan and mark the door and the desk on what you send.
