1. Overall Implementation Plan

1.1 Zoned Fragrance Layout
We formulate different deployment schemes according to the exhibition area, ceiling height and functional divisions:
1. Large integrated exhibition hall (over 1000㎡, ceiling height ≥4m)
Adopt the central air duct fragrance system matched with central air conditioning and fresh air systems. The main machines are hidden in the equipment room, and nano fragrance is evenly delivered to the whole venue through air ducts. No exposed equipment will damage the decorative aesthetic of the exhibition hall.
2. Partitioned theme exhibition areas (each independent area 50–500㎡)
Equip each area with separate wall-mounted or vertical intelligent fragrance diffusers. The fragrance type, concentration and operation time can be independently customized for different zones. Additional diffusers are arranged in corridors, registration desks and rest areas for supplementary fragrance diffusion.
3. Temporary pop-up booths
Portable high-power commercial diffusers are available, which can be used by plugging in power. They can be quickly disassembled and moved for repeated use after the exhibition.

1.2 Intelligent Management System
All diffuser models support WiFi cloud background intelligent control:
– Remote timing setting: release light fragrance in advance before opening, increase fragrance concentration during peak passenger flow, and automatically shut down after closing
– Real-time monitoring of essential oil stock with low-oil reminder alarm for refilling
– Unified cluster control of multiple devices; one-click switching of fragrance modes for opening ceremonies, daily visits and VIP receptions

1.3 Custom Fragrance Supporting Service
1. Mature fragrance library: Hundreds of ready-made fragrances including woody, white tea, citrus, fresh herbal and light luxury floral scents, matching cultural museums, auto shows, art galleries, enterprise brand pavilions and other scenarios.
2. Exclusive customized blending: Develop unique memory fragrances combining the exhibition hall brand IP and exhibit cultural characteristics.
3. Safe essential oil standards: All essential oils pass IFRA (International Fragrance Association) certification and SGS non-toxic and low-sensitivity tests. They are non-corrosive and free of oil stains, and will not damage display boards, artworks, leather exhibits; safe for children and pets.

1.4 Full-cycle Operation and Maintenance Service
Provide one-stop full-process service: on-site space measurement, design of fragrance point layout drawings, installation and debugging, regular essential oil replacement and equipment maintenance. Sign annual maintenance packages for permanent exhibition venues, and provide on-site technical support for short-term exhibition projects.

2. Core Advantages of Installing Fragrance Systems in Exhibition Halls

1. Create exclusive olfactory brand memory and upgrade the grade of the exhibition hall
Add a new olfactory identification dimension on the basis of vision. Uniform and soft light fragrance replaces pungent air fresheners, significantly improving the high-end texture of the space, and enhancing visitors’ favorable impression and memory of the exhibition hall and exhibitor brands.
2. Effectively neutralize peculiar smells and optimize visiting experience
Quickly decompose body sweat odor, decorative plate peculiar smell, mildew in underground exhibition halls and food smell in catering rest areas, keep the air fresh all day long, and avoid stuffiness and dizziness during long-time visiting.
3. Set off scene atmosphere and highlight the tonality of exhibits
– Cultural and historical museums: Calm cedar and sandalwood create a quiet and profound atmosphere
– Art and cultural and creative exhibition halls: Elegant white tea and lily of the valley enhance soft artistic sense
– Automobile and science and technology exhibition halls: Cool wood and ocean fragrance highlight avant-garde and light luxury texture
– Children’s popular science pavilions: Mild citrus and vanilla adopt safe and mild formulas to soothe emotions
4. The equipment is hidden and low-noise without interfering with the exhibition design
Hidden duct main machines and ultra-thin wall-mounted units run at low noise (≤35 decibels), and will not interfere with explanation, visiting, shooting and exhibit display.
5. Energy-saving and stable long-term operation, saving labor costs
The two-fluid nano cold atomization technology reduces essential oil consumption and improves utilization rate. Industrial movement supports stable 24-hour long-time operation with low failure rate; the intelligent background reduces manual inspection frequency.
6. Lengthen visitors’ staying time and improve negotiation conversion rate
Visitors are willing to stay longer in a comfortable fragrant environment; enterprise brand exhibition halls can boost customers’ willingness to negotiate, and exhibition booths can retain more passenger flow.

3. Standard Selection Guide for Exhibition Hall Fragrance Diffusers

3.1 Match models according to space volume (core standard)
Space specification: 5–200㎡ (conventional ceiling height 2.8–3.2m)
Recommended model: Small wall-mounted commercial diffuser
Coverage capacity: 200–600m³
Applicable scenario: Small independent exhibition room, reception room, registration desk

Space specification: 200–800㎡ / ceiling height 3–4.5m
Recommended model: Medium-power vertical diffuser / duct split unit
Coverage capacity: 600–1800m³
Applicable scenario: Medium independent exhibition hall, corridor, atrium

Space specification: Over 800㎡, high vaulted ceiling, whole building exhibition venue
Recommended model: Central duct fragrance main unit
Coverage capacity: More than 3000m³ full coverage
Applicable scenario: Large expo center, main museum building

3.2 Core technical screening (prioritize water-free two-fluid nano cold atomization)
1. Give priority to water-free two-fluid nano atomization
The atomized particles are fine and dry, without water vapor and oil stains, and will not pollute display boards, metal, cloth and cultural relic exhibits. Compared with ultrasonic water-adding diffusers, it avoids bacterial growth, saves consumables, and makes fragrance spread farther and more evenly.
2. Hardware configuration requirements
– Pump body: Silent industrial high-pressure pump, supporting stable 7×24 hours continuous operation
– Oil tank: Food-grade anti-corrosion aluminum/PP large-capacity tank (500–1000ml), reducing frequent oil filling
– Shell: Flame-retardant aluminum alloy, simple and versatile appearance matching all kinds of exhibition hall decoration styles

3.3 Intelligence and compatibility requirements
1. It must support APP/cloud remote cluster control, timing program and power-off memory; large multi-equipment exhibition halls need a unified group management background.
2. Duct-type diffusers need to be seamlessly connected with central air conditioning, fresh air and fan coil units without affecting the air pressure of the original air supply system.
3. The actual operating noise shall be lower than 38 decibels to avoid buzzing noise in quiet exhibition spaces.

3.4 Non-negotiable essential oil safety thresholds
1. Fragrance oil must provide IFRA official certification and SGS safety test reports, low sensitization, free of harmful volatile substances.
2. Reject cheap chemical synthetic essence; prefer essential oils blended with natural base materials, with soft layered fragrance that will not cause dizziness after long inhalation.
3. Support adjustable concentration gears; exhibition halls are only suitable for long-lasting light fragrance, and strong heavy-fragrance models are prohibited.

3.5 Scenario differentiated selection
– Permanent cultural and art museums: Adopt fully hidden duct installation to protect space aesthetics without exposed equipment
– Short-term exhibition pop-up booths: Choose movable installation-free vertical models for repeated handling and reuse
– Mother and baby & children-themed exhibition areas: Select extra infant-friendly non-irritating fragrance formulas

4. Simple Project Implementation Process

1. On-site survey of space size, air conditioning layout and functional division of each area
2. Output fragrance point layout drawing, equipment list, fragrance scheme and budget quotation
3. On-site installation and debugging, fine-tune fragrance concentration and operation schedule on site
4. Hand over intelligent background account and conduct operation training
5. Sign monthly/quarterly essential oil supply and equipment maintenance contract
