If you're choosing an aromatherapy solution, understanding how atomization technologies work matters. Two - fluid atomization is a top pick for great aroma devices, beating traditional ultrasonic atomization in key areas that affect your experience, oil quality, and device reliability. Here's a simple breakdown of its advantages.
1. How They Make Mist
- Two - fluid atomization: Uses fast - moving compressed air to split essential oil into tiny droplets at a precise nozzle. There's no heat or vibration to mess with the oil, and you can adjust how much mist comes out by changing air pressure or liquid flow.
- Ultrasonic atomization: Relies on high - frequency vibrations to create bubbles in the liquid. These bubbles pop and turn the liquid into mist. It's cheap and simple but vibrations and slight heat can change the oil.
2. Mist Particle Size
- Two - fluid atomization: Makes super tiny particles (1–5 μm). These small droplets stay in the air longer, spread evenly, and don't settle on surfaces much. Great for big spaces like hotels or offices.
- Ultrasonic atomization: Creates larger particles (10–30 μm) that fall quickly. You need to place the device close by and move it often for a consistent smell.
3. Essential Oil Compatibility
- Two - fluid atomization: Works at room temperature with no vibrations. This keeps heat - sensitive compounds in oils (like those in lavender or tea tree oil) intact. It also works with thick oils and doesn't create unwanted byproducts.
- Ultrasonic atomization: Vibrations and mild heat (35–45°C with long use) can break down oil molecules, fade scents, and leave residue on the device that needs cleaning.
4. Energy and Reliability
- Two - fluid atomization: Uses energy efficiently for air compression and liquid delivery. It has no parts that wear out quickly (like ultrasonic transducers), so it lasts 2–3 times longer with little maintenance.
- Ultrasonic atomization: While it uses less power at first, the vibrating part (transducer) needs replacing every 6–12 months in commercial use, adding to long - term costs. Mist output also gets uneven over time.
5. Where They Work Best
Two - fluid atomization is flexible:
- Commercial (hotels, malls): One device covers 50–100㎡ and works 24/7. Ultrasonic needs 2–3 times more devices and more upkeep.
- Home use: Keeps rare oils pure and leaves no residue. Ultrasonic needs weekly cleaning.
- Custom blends: Works with oil - water or oil - only mixes. Ultrasonic clogs with oil - heavy blends.
Conclusion
For consistent performance, oil preservation, and long - lasting devices, two - fluid atomization is the way to go. It's perfect for both commercial and high - end home aromatherapy. At Dermey, our two - fluid solutions make devices simpler for partners and better for users.
