One Large Scent Machine vs Multiple Smaller Machines for an Appliance Showroom

One, and the reason is not a preference for big machines; it is what fragrance does in a room. Start with the thing every scent source has in common. A nebuliser - a Vaayu, an Angaan, any cold-air machine - breaks oil into a dry aerosol and pushes it into the air the air-conditioning is moving. From the nozzle outward it makes a gradient: strongest at the source, fading with distance, stretched in the direction the supply runs and cut off at the return. Placement is the craft of laying that one gradient across the floor so the strong end is noticed at the first display and the weak end is still just present at the specification table. Now put a second source in the same connected air. You do not get a longer gradient; you get two gradients pointing at each other, and the floor carries both wherever they overlap - usually a band somewhere in the middle that is stronger than either end, on steel, glass and stone with nothing to absorb it, while the two far edges are the weak ends of both. The advisor stands in the band all day. The visitor walks through it. And then the second effect starts: the person at the door can smell only her edge, which seems faint, so she turns her machine up; the manager at the far end does the same with his; and within a month the middle of the floor is a fragrance shop that nobody chose and nobody can attribute. One machine has one dial, set once from the far end at five in the afternoon with the whole team, and locked. That is the evenness argument. The cost argument is plain arithmetic. Two Vaayus at ₹11,999 each come to about what one Angaan costs at ₹25,999 - within a couple of thousand rupees - and they are rated to 2,000m³ between them against the Angaan's 3,000m³. A third less air for the same money, with two tanks to refill, two schedules to keep in step, two mounting points, two key-locks and the gradient problem thrown in; the four 100ml bottles in each Vaayu box are its supply, and refill availability is confirmed with SOSA either way, but one machine is one supply to think about. Three Vaayus cost more than an Angaan and cover no more, because in one volume they compete rather than combine. The same logic runs all the way down the ladder: several Sukoons across a floor are several scented desks with a quieter corridor between them, and several reeds are several desk zones - reeds are a volume control, never a range control, and adding bottles adds strength at the same spots, not reach. So when are several machines right? When the building has several volumes of air. A second floor with a solid floor between it and the ground, a wing on its own air-handling unit behind doors that stay shut, a closed designer studio - the air in each of those does not mix with the main floor's, so a machine on the main floor never reaches them and each needs its own. Then each volume gets one machine sized for its own cubic metres: an Angaan for a 6,000 sq ft main floor, a Vaayu for a 1,500 sq ft wing, a reed for a 300 sq ft closed lounge, all in one register, each level judged from its own far end. What is never a second volume: the demo kitchen and coffee counter, which share the floor's air and are handled by placement and the schedule; a partition, which is a height problem; a long floor, which is a duct or third-point problem. Fragrance is an interiors decision, like lighting or music: SOSA makes no claim that it changes footfall, dwell time, 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 the coffee counter stay unscented while they run whatever the count. The 3,000 sq ft page is where this argument first arises, the 7,500 sq ft page is the one-volume-or-two test in full, and how to calculate scent-machine requirements is the method for counting volumes before counting machines.
