TW-SI02, TW-MI01 and TW-LI01 can be shortlisted for HVAC project review because their quotations list an external-connection option. That wording does not confirm a complete HVAC kit. TW-SI02 covers 300–500m³, TW-MI01 covers 2000–3000m³ and TW-LI01 covers 5000–8000m³; the interface, tubing, accessories and site must still be confirmed.

| Site input | Why it changes the recommendation |
|---|---|
| Length, width and ceiling height | Establishes the basic volume and whether the published range is relevant |
| HVAC, fresh-air or local air handler | Determines where fragrance can enter and how it is distributed |
| Airflow and zone diagram | Shows which rooms receive air and which areas may require separate control |
| Operating schedule | Fragrance cannot circulate through an inactive system in the same way |
| Power and installation access | Affects machine position, cable route and routine servicing |
| Refill and maintenance route | The unit must remain accessible without disrupting occupied areas |
Commission at low output
Begin with a conservative schedule and allow the fragrance to circulate before changing settings. Check the entrance, occupied zone and far side of the system. Strong fragrance close to the injection point does not prove even distribution elsewhere.
Information to send for a project review
- Floor plan and total volume
- Air-handler and fresh-air information
- Supply and return-air locations
- Zones that should and should not receive fragrance
- Available voltage and proposed machine location
- Destination country and installation responsibility
- Photos of the proposed service area where available
Frequently asked questions
Which LUMEN NARRATE models can be reviewed for HVAC projects?
The current quotations for TW-SI02, TW-MI01 and TW-LI01 list an external-connection option. This does not by itself confirm a complete HVAC kit; the interface, tubing, accessories and site conditions must be reviewed. Their published coverage ranges are 300–500, 2000–3000 and 5000–8000m³ respectively.
Does an HVAC scent diffuser require duct modifications?
The existing air system and proposed connection need review. Confirm the injection point, tubing route, fixing method and access with the responsible HVAC installer. An external-connection option does not mean every duct can accept the machine without site work or additional accessories.
Can an HVAC scent machine serve several zones?
It may serve the zones reached by the connected airflow, but the actual duct layout and controls must be reviewed. Areas that require different schedules or no fragrance may need separate planning.
How much fragrance oil does an HVAC system consume?
A verified consumption rate is not listed in the current quotation. Confirm the compatible oil, output program and operating hours, then measure use during commissioning. Bottle capacity alone cannot establish a daily consumption figure.
What noise level should I expect from the machine?
The current quotation does not list measured noise values. Request a result for the selected version with the operating mode, measurement distance and background conditions identified, then review the proposed service location.
Send the site information before requesting a model
A floor plan and basic air-system notes are more useful than floor area alone.
