Fragrance oil for scent machines

Match the refill to the machine

These waterless machines atomize compatible fragrance oil; they are not water humidifiers. Each model takes a different bottle size, so the first step is to match the refill to the machine already on site. The table below uses the published oil capacity for every model. Order the refill that matches the machine, and confirm the refill pack in the quotation.

Oil capacity is the bottle size, not a consumption rate. A larger bottle means fewer refills, not a fixed number of operating days. The scent-machine sizing guide explains how volume becomes a shortlist rather than a performance guarantee.

Choose a scent family by space

Standard scents are supplied as machine consumables, described by direction rather than a fixed ingredient list. The exact formulation is confirmed with the fragrance selection in the quotation. Use the space to narrow the family, then test the selected scent in the real room before a multi-site order.

Hotel lobbies usually take a warm, welcoming direction that reads well in a large public space without becoming heavy at the entrance. Guest rooms take a lighter, restful direction that does not compete with sleep. SPA and treatment rooms take a calm direction that suits low light and quiet service; see the SPA scenting page for the space planning behind it. Retail spaces take the brand direction already used in packaging and store design, so the scent matches what customers see. Offices take a neutral, low-key direction that stays in the background during working hours.

One fragrance name is not enough to repeat an order. Record the approved fragrance reference, the compatible oil, the machine version and the program it runs on, and keep a sealed reference bottle for reorders. When a chain runs the same scent across several locations, that reference is what keeps every store smelling the same.

How long does a refill last?

There is no fixed number of days in the current quotation, because consumption depends on the output setting, the operating hours, the space volume and the airflow. The reliable way to plan is to measure it once, under the program you will actually run.

Observed daily use = oil volume used during the trial ÷ operating days in the trial

Run the trial in one representative zone with the agreed fragrance and program, then use the observed daily use to plan replenishment for comparable zones. Keep a separate allowance for commissioning, when settings are still being adjusted. Repeat the trial when a major setting or formulation changes. No measured consumption rate is published for the six models in the current quotation.

Wholesale replenishment and reordering

Diffuser oil wholesale orders are planned around the same reference used for the first purchase. Agree the fragrance reference, the refill sizes per model, the quantity per reorder and the destination before the first bulk shipment, so replenishment is a repeat order rather than a new negotiation each time.

Keep at least one sealed spare bottle for each zone in regular use, so a refill never waits on a shipment. Store bottles upright and sealed, away from heat and direct sun, and check the batch reference against the approved fragrance before refilling. Assign one person to watch stock and settings across the sites, and record each refill against the machine it went into. That record is what turns a scent program into a repeatable operation instead of a series of separate purchases.

Looking for a custom fragrance?

Standard scents on this page are supplied as consumables for the six machines. Custom fragrance development is a separate project: it starts with the scent brief, the intended spaces and the machine models it must match, and it is handled through the LUMEN NARRATE home-fragrance product line, which develops candles, reed diffusers, room sprays and coordinated home fragrance. If the brief needs a signature scent that no standard oil covers, send it through that line and keep the machine-and-refill quotation separate.
