The coil-free semi-rebuildable OFRF EMODE RFA atomizer had already begun to attract attention as early as 2016. Back then, ALTUS tried to challenge the position of traditional heating coils with its black-tech CVU heating chip, but some practical drawbacks during use ultimately made that coil revolution short-lived. Even so, ALTUS did open up new ideas for the coil-free segment.
The atomizer being shared today also uses coil-free technology. This model is the EMODE from OVALE (OFRF), and the manufacturer calls it an RFA to highlight its unique nature. It is equipped with two 0.5-ohm CVU heating elements.
Many parts of the packaging highlight the EMODE RFA’s “exclusive skills,” such as “molecular heating element,” “self-cleaning by heating,” and “ultra-long lifespan of one million uses.” Setting aside for the moment how effective these selling points really are, at a time when the atomizer market seems to be hitting a bottleneck, they certainly bring a strong sense of novelty to users.
In addition to a spare glass section, sealing rings, and tweezers, the package also includes plenty of pre-cut cotton, along with a metal guide piece to help users trim the cotton to the correct size. In fact, the EMODE RFA only requires replacing the cotton, not the “coil.”
A large warning card explains the cotton dimensions and installation precautions. For cleaning, the manufacturer emphasizes avoiding contact between the heating plates and water, largely because if a red-hot heating plate touches cold water, it may crack. In practice, however, this heating element can be cleaned of carbon buildup simply by removing the cotton and dry-burning it at a low power of 20–30W.
Aside from the highlight of the “molecular heating element,” the atomizer’s structural design is fairly mainstream. It may not be exceptionally stunning, but it certainly is not unattractive. The snake-pattern heat-insulated drip tip has a relatively wide bore, and together with the bottom airflow opening, it is clear this is mainly a direct-lung atomizer. Overall build quality is also quite good.
Several components are easy to maintain. Once disassembled, the electrode deck is clearly visible. In fact, this atomizer does not follow a standard bottom-airflow path. The heating elements can be seen on both sides of the cotton, and the vapor and heat are drawn away through the two gaps by suction. In other words, the airflow works by “carrying away” the vapor rather than “directly blowing” onto the heating element.
The EMODE RFA delivers a noticeably different experience compared with coil-based heads. It provides a softer inhale, and the e-liquid flavor is reproduced very clearly. Using the same e-liquid, compared with a traditional coil head, the EMODE RFA presents a cleaner and purer flavor. However, when used above the officially recommended 40–50W range, chain vaping causes the atomizer temperature to rise sharply.
Rebuilding is relatively simple. As long as the cotton is trimmed to the original specified thickness and size and placed correctly in the heating element area, it is ready to use. In practical terms, it is better suited to the sheet-style cotton commonly found on the market, such as Muji cotton. When the amount of cotton is appropriate, the EMODE RFA is not only resistant to leaking, but also wicks very quickly.
Those who look closely at the airflow path will notice that the EMODE RFA’s vapor is carried away by the airflow rather than being produced by the usual direct-airflow-over-coil method. With the airflow fully open, the flavor becomes diluted by excessive airflow, resulting in what we often call a “hollow” taste. Without exceeding the recommended wattage on the official website, the only solution is to close the airflow by half or more.
The set of CVUs, officially claimed to be reusable more than one million times, is clearly the core of this atomizer. Its long service life and easy cleaning—only the cotton needs to be replaced to keep it going—are exactly the kind of convenience many users have been waiting for. However, when output power is increased to achieve a fuller flavor, the heat generated by the CVU causes the atomizer body temperature to spike, which is also why it is not ideal for constant chain vaping. If the temperature issue can be solved, this could be a very practical and user-friendly atomizer......
